The REG670 is used for protection, control and monitoring of generators and generator-transformer blocks from relatively small units up to the largest generating units. The IED has a comprehensive function library, covering the requirements for most generator applications. The large number of analog inputs available enables, together with the large functional library, integration of many functions in one IED. In typical applications two IED units can provide total functionality, also providing a high degree of redundancy. REG670 can as well be used for protection and control of shunt reactors. Stator earth fault protection, both traditional 95% as well as 100% injection and 3rd harmonic based are included. When the injection based protection is used, 100% of the machine stator winding, including the star point, is protected under all operating modes. The 3rd harmonic based 100% stator earth fault protection uses 3rd harmonic differential voltage principle. Injection based 100% stator earth fault protection can operate even when machine is at standstill. Well proven algorithms for pole slip, underexcitation, rotor earth fault, negative sequence current protections, and so on, are included in the IED. The generator differential protection in the REG670 adapted to operate correctly for generator applications where factors as long DC time constants and requirement on short trip time have been considered. As many of the protection functions can be used as multiple instances there are possibilities to protect more than one object in one IED. It is possible to have protection for an auxiliary power transformer integrated in the same IED having main protections for the generator. The concept thus enables very cost effective solutions. The REG670 also enables valuable monitoring possibilities as many of the process values can be transferred to an operator HMI. The wide application flexibility makes this product an excellent choice for both new installations and for refurbishment in existing power plants. Forcing of binary inputs and outputs is a convenient way to test wiring in substations as well as testing configuration logic in the IEDs. Basically it means that all binary inputs and outputs on the IED I/O modules (BOM, BIM, IOM & SOM) can be forced to arbitrary values. Central Account Management is an authentication infrastructure that offers a secure solution for enforcing access control to IEDs and other systems within a substation. 1MRK 502 071-UEN - Section 2 Application Generator protection REG670 2.2 IEC and Injection equipment REX060, REX061, REX062 35 Application manual

distribution of such, a procedure completely transparent to the user. The Flexible Product Naming allows the customer to use an IED-vendor independent IEC 61850 model of the IED. This customer model will be exposed in all IEC 61850 communication, but all other aspects of the IED will remain unchanged (e.g., names on the local HMI and names in the tools). This offers significant flexibility to adapt the IED to the customers' system and standard solution. Communication via optical connections ensures immunity against disturbances. By using patented algorithm REG670 (or any other product from 670 series) can track the power system frequency in quite wide range from 9Hz to 95Hz (for 50Hz power system). In order to do that preferably the three-phase voltage signal from the generator terminals shall be connected to the IED. Then IED can adopt its filtering algorithm in order to properly measure phasors of all current and voltage signals connected to the IED. This feature is essential for proper operation of the protection during generator start-up and shut-down procedure. REG670 can be used in applications with the IEC/UCA 61850-9-2LE process bus with up to eight merging units (MU) depending on the other functionality included in the IED. This adaptive filtering is ensured by proper configuration and settings of all relevant pre-processing blocks, see figure 344 and 345. Note that in all pre-configured REG670 IEDs such configuration and settings are already made and that three-phase voltage at the generator terminals are used for frequency tracking. With such settings REG670 will be able to properly estimate the magnitude and the phase angle of measured current and voltage phasors in this wide frequency range. Note that the following functions will then operate properly in the whole frequency interval: • Generator differential • Transformer differential • Four step overcurrent protection (DFT based measurement) • Four step residual overcurrent protection • Over/under voltage protection (DFT based measurement) • Residual overvoltage protection • Overexcitation protection • General current and voltage protection • Directional over/under power function • Measurement function (that is, MMXU) • and so on Note that during secondary injection testing of this feature, it is absolutely necessary to also inject the voltage signals used for frequency tracking even when a simple overcurrent protection is tested.

storage schemes) four step overcurrent protection with RMS measurement shall be used. This function is able to operate for current signals within frequency range from 1Hz up to 100Hz and it is not at all dependent on any voltage signal. Its pickup for very low frequency is only determined by main CT capability to transfer low frequency current signal to the secondary side. However it shall be noted that during such low frequency conditions this function will react on the measured current peak values instead of usual RMS value and that its operation shall be instantaneous (that is, without any intentional time delay). Function can be used either as normal overcurrent function or even as generator differential function when currents from two generator sides are summed and connected to the four step overcurrent function. Typically for such installations dedicated overcurrent steps are used during such low frequency conditions while some other overcurrent steps with different setting for pickup value and time delay are used during normal machine operation. Such logic can be easily arranged in REG670 application configuration tool. Four step overcurrent protection with RMS measurement shall also be used as machine overcurrent and differential protection during electrical braking. During such operating condition intentional three-phase short-circuit is made at the machine terminal. This will effectively force voltages at the machine terminal to zero and effectively disabled voltage based frequency tracking in REG670. Similar logic as described for pump-storage scheme above can be used. 1MRK 502 071-UEN - Section 2 Application Generator protection REG670 2.2 IEC and Injection equipment REX060, REX061, REX062 37 Application manual

3.1.1 Introduction 3.1.1.1 Description of configuration A20 REG670 A20 configuration is used in applications where only generator protection within one IED is required. REG670 A20 is always delivered in 1/2 of 19" case size. Thus only 12 analogue inputs are available. This configuration includes generator low impedance, differential protection and all other typically required generator protection functions. Note that 100% stator earth fault function and Pole Slip protection function are optional. REG670 A20 functional library includes additional functions, which are not configured, such as additional Overcurrent protection, additional Multipurpose protection functions, Synchronizing function, and so on. It is as well possible to order optional two-winding transformer differential or high impedance differential protection functions which than can be used instead of basic low-impedance generator differential protection. Note that REG670 A20 must be re-configured if any additional or optional functions are used. 1MRK 502 071-UEN - Section 3 Configuration Generator protection REG670 2.2 IEC and Injection equipment REX060, REX061, REX062 57 Application manual

measurement results and correct protection operations. For power measuring, all directional and differential functions, the directions of the input currents must be defined in order to reflect the way the current transformers are installed/connected in the field ( primary and secondary connections ). Measuring and protection algorithms in the IED use primary system quantities. Setting values are in primary quantities as well and it is important to set the data about the connected current and voltage transformers properly. An AISVBAS reference PhaseAngleRef can be defined to facilitate service values reading. This analog channel's phase angle will always be fixed to zero degrees and remaining analog channel's phase angle information will be shown in relation to this analog input. During testing and commissioning of the IED, the reference channel can be changed to facilitate testing and service values reading. The IED has the ability to receive analog values from primary equipment, that are sampled by Merging units (MU) connected to a process bus, via the IEC 61850-9-2 LE protocol. The availability of VT inputs depends on the ordered transformer input module (TRM) type. 4.2 Setting guidelines The available setting parameters related to analog inputs are depending on the actual hardware (TRM) and the logic configuration made in PCM600. 4.2.1 Setting of the phase reference channel All phase angles are calculated in relation to a defined reference. An appropriate analog input channel is selected and used as phase reference. The parameter PhaseAngleRef defines the analog channel that is used as phase angle reference. 1MRK 502 071-UEN - Section 4 Analog inputs Generator protection REG670 2.2 IEC and Injection equipment REX060, REX061, REX062 63 Application manual

transformer input module (TRM) is selected as the phase reference. The first VT channel number depends on the type of transformer input module. For a TRM with 6 current and 6 voltage inputs the first VT channel is 7. The setting PhaseAngleRef=7 shall be used if the phase reference voltage is connected to that channel. 4.2.2 Setting of current channels The direction of a current to the IED is depending on the connection of the CT. Unless indicated otherwise, the main CTs are supposed to be star connected and can be connected with the earthing point to the object or from the object. This information must be set in the IED. The convention of the directionality is defined as follows: A positive value of current, power, and so on means that the quantity has the direction into the object and a negative value means direction out from the object. For directional functions the direction into the object is defined as Forward and the direction out from the object is defined as Reverse. See Figure 11 A positive value of current, power, and so on (forward) means that the quantity flows towards the object. A negative value of current, power, and so on (reverse) means that the quantity flows away from the object. See Figure 11. Protected Object Line, transformer, etc Forward Reverse Definition of direction for directional functions Measured quantity is positive when flowing towards the object e.g. P, Q, I Reverse Forward Definition of direction for directional functions e.g. P, Q, I Measured quantity is positive when flowing towards the object Set parameter CTStarPoint Correct Setting is "ToObject" Set parameter CTStarPoint Correct Setting is "FromObject" en05000456.vsd IEC05000456 V1 EN Figure 11: Internal convention of the directionality in the IED With correct setting of the primary CT direction, CTStarPoint set to FromObject or ToObject, a positive quantities always flowing towards the protected object and a direction defined as Forward always is looking towards the protected object. The following examples show the principle. Section 4 1MRK 502 071-UEN - Analog inputs 64 Generator protection REG670 2.2 IEC and Injection equipment REX060, REX061, REX062 Application manual

The settings for CT direction shall be done according to the figure. To protect the line, direction of the directional functions of the line protection shall be set to Forward. This means that the protection is looking towards the line. 4.2.2.2 Example 2 Two IEDs used for protection of two objects and sharing a CT. 1MRK 502 071-UEN - Section 4 Analog inputs Generator protection REG670 2.2 IEC and Injection equipment REX060, REX061, REX062 65 Application manual

Correct setting is "FromObject" IED IED IEC05000460 V2 EN Figure 13: Example how to set CTStarPoint parameters in the IED This example is similar to example 1, but here the transformer is feeding just one line and the line protection uses the same CT as the transformer protection does. The CT direction is set with different reference objects for the two IEDs though it is the same current from the same CT that is feeding the two IEDs. With these settings, the directional functions of the line protection shall be set to Forward to look towards the line. 4.2.2.3 Example 3 One IED used to protect two objects.

Set parameter CTStarPoint with Transformer as reference object. Correct setting is "ToObject" Reverse Forward Definition of direction for directional line functions Setting of current input: Set parameter CTStarPoint with Transformer as reference object. Correct setting is "ToObject" IED IEC05000461 V2 EN Figure 14: Example how to set CTStarPoint parameters in the IED In this example, one IED includes both transformer and line protections and the line protection uses the same CT as the transformer protection does. For both current input channels, the CT direction is set with the transformer as reference object. This means that the direction Forward for the line protection is towards the transformer. To look towards the line, the direction of the directional functions of the line protection must be set to Reverse. The direction Forward/Reverse is related to the reference object that is the transformer in this case. When a function is set to Reverse and shall protect an object in reverse direction, it shall be noted that some directional functions are not symmetrical regarding the reach in forward and reverse direction. It is in first hand the reach of the directional criteria that can differ. Normally it is not any limitation but it is advisable to have it in mind and check if it is acceptable for the application in question. If the IED has sufficient number of analog current inputs, an alternative solution is shown in Figure 15. The same currents are fed to two separate groups of inputs and the line and transformer protection functions are configured to the different inputs. The CT direction for the current channels to the line protection is set with the line as reference object and the directional functions of the line protection shall be set to Forward to protect the line. 1MRK 502 071-UEN - Section 4 Analog inputs Generator protection REG670 2.2 IEC and Injection equipment REX060, REX061, REX062 67 Application manual

Figure 16: Example how to set CTStarPoint parameters in the IED For busbar protection, it is possible to set the CTStarPoint parameters in two ways. The first solution will be to use busbar as a reference object. In that case for all CT inputs marked with 1 in Figure 16, set CTStarPoint = ToObject, and for all CT inputs marked with 2 in Figure 16, set CTStarPoint = FromObject. The second solution will be to use all connected bays as reference objects. In that case for all CT inputs marked with 1 in Figure 16, set CTStarPoint = FromObject, and for all CT inputs marked with 2 in Figure 16, set CTStarPoint = ToObject. Regardless which one of the above two options is selected, busbar differential protection will behave correctly. 1MRK 502 071-UEN - Section 4 Analog inputs Generator protection REG670 2.2 IEC and Injection equipment REX060, REX061, REX062 69 Application manual

For a 1000/1 A CT, the following settings shall be used: • CTprim = 1000 (value in A) • CTsec =1 (value in A). 4.2.2.4 Examples on how to connect, configure and set CT inputs for most commonly used CT connections Figure 17 defines the marking of current transformer terminals commonly used around the world: In the SMAI function block, you have to set if the SMAI block is measuring current or voltage.

Note that for these two cases the CT polarity marking is correct! It shall be noted that depending on national standard and utility practices, the rated secondary current of a CT has typically one of the following values: • 1A • 5A Section 4 1MRK 502 071-UEN - Analog inputs 70 Generator protection REG670 2.2 IEC and Injection equipment REX060, REX061, REX062 Application manual

• 2A • 10A The IED fully supports all of these rated secondary values. It is recommended to: • use 1A rated CT input into the IED in order to connect CTs with 1A and 2A secondary rating • use 5A rated CT input into the IED in order to connect CTs with 5A and 10A secondary rating 4.2.2.5 Example on how to connect a star connected three-phase CT set to the IED Figure 18 gives an example about the wiring of a star connected two-phase CT set to the IED. It gives an overview of the actions which are needed to make this measurement available to the built-in protection and control functions within the IED as well.

It shall be noted that for all these current inputs the following setting values shall be entered for the example shown in Figure 18. • CTprim=600A • CTsec=5A • CTStarPoint=ToObject Ratio of the first two parameters is only used inside the IED. The third parameter (CTStarPoint=ToObject) as set in this example causes no change on the measured currents. In other words, currents are already measured towards the protected object.

channels of the preprocessing function block 4). Depending on the type of functions, which need this current information, more than one preprocessing block might be connected in parallel to the same three physical CT inputs. 4) The preprocessing block that has the task to digitally filter the connected analog inputs and calculate: • fundamental frequency phasors for all three input channels • harmonic content for all three input channels • positive, negative and zero sequence quantities by using the fundamental frequency phasors for the first three input channels (channel one taken as reference for sequence quantities) These calculated values are then available for all built-in protection and control functions within the IED, which are connected to this preprocessing function block. For this application most of the preprocessing settings can be left to the default values. If frequency tracking and compensation is required (this feature is typically required only for IEDs installed in power plants), then the setting parameters DFTReference shall be set accordingly. Section SMAI in this manual provides information on adaptive frequency tracking for the signal matrix for analogue inputs (SMAI). 5) AI3P in the SMAI function block is a grouped signal which contains all the data about the phases L1, L2, L3 and neutral quantity; in particular the data about fundamental frequency phasors, harmonic content and positive sequence, negative and zero sequence quantities are available. AI1, AI2, AI3, AI4 are the output signals from the SMAI function block which contain the fundamental frequency phasors and the harmonic content of the corresponding input channels of the preprocessing function block. AIN is the signal which contains the fundamental frequency phasors and the harmonic content of the neutral quantity. In this example, GRP2N is not connected so this data is calculated by the preprocessing function block on the basis of the inputs GRPL1, GRPL2 and GRPL3. If GRP2N is connected, the data reflects the measured value of GRP2N. Another alternative is to have the star point of the three-phase CT set as shown in Figure 19: 1MRK 502 071-UEN - Section 4 Analog inputs Generator protection REG670 2.2 IEC and Injection equipment REX060, REX061, REX062 73 Application manual

Figure 19: Star connected three-phase CT set with its star point away from the protected object In the example, everything is done in a similar way as in the above described example (Figure 18). The only difference is the setting of the parameter CTStarPoint of the used current inputs on the TRM (item 2 in Figure 19 and 18): • CTprim=600A • CTsec=5A • CTStarPoint=FromObject The ratio of the first two parameters is only used inside the IED. The third parameter as set in this example will negate the measured currents in order to ensure that the currents are measured towards the protected object within the IED. A third alternative is to have the residual/neutral current from the three-phase CT set connected to the IED as shown in Figure 19.

It shall be noted that for all these current inputs the following setting values shall be entered. • CTprim=800A • CTsec=1A • CTStarPoint=FromObject • ConnectionType=Ph-N The ratio of the first two parameters is only used inside the IED. The third parameter as set in this example will have no influence on measured currents (that is, currents are already measured towards the protected object). 4) Are three connections made in the Signal Matrix tool (SMT) and Application configuration tool (ACT), which connects these three current inputs to the first three input channels on the preprocessing function block 6).

primary current value is set as parameter CTPrim under the IED TRM settings. For all other protection applications (e.g. generator, shunt reactor, shunt capacitor and transformer protection) it is typically desirable to set IBase parameter equal to the rated current of the protected object. However this is only recommended to do if the rated current of the protected object is within the range of 40% to 120% of the selected CT rated primary current. If for any reason (e.g. high maximum short circuit current) the rated current of the protected object is less than 40% of the rated CT primary current, it is strongly recommended to set the parameter IBase in the IED to be equal to the largest rated CT primary current among all CTs involved in the protection scheme and installed on the same voltage level. This will effectively make the protection scheme less sensitive; however, such measures are necessary in order to avoid possible problems with loss of the measurement accuracy in the IED. Regardless of the applied relationship between the IBase parameter and the rated CT primary current, the corresponding minimum pickup of the function on the CT secondary side must always be verified. It is strongly recommended that the minimum pickup of any instantaneous protection function (e.g. differential, restricted earth fault, distance, instantaneous overcurrent, etc.) shall under no circumstances be less than 4% of the used IED CT input rating (i.e. 1A or 5A). This corresponds to 40mA secondary for IED 1A rated inputs and to 200mA secondary for IED 5A rated inputs used by the function. This shall be individually verified for all current inputs involved in the protection scheme. Note that exceptions from the above 4% rule may be acceptable for very special applications (e.g. when Multipurpose filter SMAIHPAC is involved in the protection scheme). 4.2.4 Setting of voltage channels As the IED uses primary system quantities, the main VT ratios must be known to the IED. This is done by setting the two parameters VTsec and VTprim for each voltage channel. The phase-to-phase value can be used even if each channel is connected to a phase-to-earth voltage from the VT. 4.2.4.1 Example Consider a VT with the following data: 132 110 3 3 kV V EQUATION2016 V1 EN (Equation 1) The following setting should be used: VTprim=132 (value in kV) VTsec=110 (value in V) 1MRK 502 071-UEN - Section 4 Analog inputs Generator protection REG670 2.2 IEC and Injection equipment REX060, REX061, REX062 81 Application manual

In case of a solid earth fault close to the VT location the primary value of 3Uo will be equal to: 3 0 3 3 Ph Ph Ph N U U U - - = × = × EQUATION1921 V3 EN (Equation 3) The primary rated voltage of an open Delta VT is always equal to UPh-E. Three series connected VT secondary windings gives a secondary voltage equal to three times the individual VT secondary winding rating. Thus the secondary windings of open delta VTs quite often have a secondary rated voltage equal to one third of the rated phase- to-phase VT secondary voltage (110/3V in this particular example).
