voltage has been disconnected. Non-observance can result in death, personal injury or substantial property damage. Only a competent electrician is allowed to carry out the electrical installation. National and local electrical safety regulations must always be followed. The frame of the IEDs has to be carefully earthed. Whenever changes are made in the IEDs, measures should be taken to avoid inadvertent tripping. The IEDs contain components which are sensitive to electrostatic discharge. Unnecessary touching of electronic components must therefore be avoided. 1MRK 511 451-UEN B Section 2 Safety information Distributed busbar protection REB500 5 Communication protocol manual IEC60870-5-103 © Copyright 2019 ABB.

GUID-FC8C1289-F943-4E92-A50E-BDA7281A5337 v1 3.1 Introduction GUID-7A41F2A2-F366-4D30-9D76-BB6279380110 v2 An interface is available for connecting the numerical busbar protection to a station automation system or station monitoring system (SCS/SMS). For an overview of REB500’s communication interfaces, see the Operation manual. In contrast to feeder control and protection bay units, REB500 is equipped with only a single interbay bus interface via which all the REB500 bay units in the entire station communicate. This has to be taken into account by the various bus protocols. This document applies for IEC60870-5-103. However, Section 3 of this document also contains information of a second IBB using IEC61850-8-1 if configured. 3.2 Basic configuration GUID-A112B99B-E8BF-4750-8E26-D9C9BD9F6048 v2 The fourth octet in the Data Unit Identification field of an ASDU determines the common address of ASDU. It normally has to be the same as the station address on the link layer. Exceptions are permitted where additional common ASDU addresses are needed because of multiple instances of functions. In case of REB500, this exception allowed in the IEC recommendation is used to be able to address the Central Unit and the Bay Units via a single physical connection. Common Address of ASDU – CAA Basic setting: 0 Central Unit 1-60 Bay Units 255 Global address The dialog for configuring the communication is accessed by selecting HMI500 Configuration/Communication/SCS Configuration. 1MRK 511 451-UEN B Section 3 Interbay bus functions Distributed busbar protection REB500 7 Communication protocol manual IEC60870-5-103 © Copyright 2019 ABB.

To which IBB an event is sent is determined by selecting the appropriate check box IBB 1 or IBB 2 when configuring the signal. As the 61850 model is implemented as defined by the standard, no custom assignments can be made for the IBB associated with 61850.

Figure 4: Configuring signals as events Diagnostic and system events are always available for transfer whichever protocol is in use and cannot be configured. The IEC 60870-5-103 section only appears when the protocol is configured. 3.4 Transfer of differential current values 3.4.1 The delta/dead band algorithm GUID-85BE2C1A-DD67-4564-99E1-CF504CBD06D7 v1 To keep the load on the IBB as low as possible, the bus zone differential currents are checked cyclically, but only actually transferred via the bus if the value has changed.

belonging to the respective zone are sent to the SCS/SMS. sum = sum + |current – last| if sum > delta then sum = 0 if current < deadband then current = 0 endif send current endif last = current The system continuously performs the above algorithm: It adds up the absolute difference between the last two measurements (current and last) since the last status update was sent (sum). As soon as sum is greater than the threshold delta a new event will be sent with the current value. If this value is below the deadband threshold, the value 0 will be sent instead. 3.4.2 Configuring the SCS differential current parameter GUID-DF29CA42-6DDD-459D-A610-175B597D83C9 v2 The precise conditions for sending differential currents to the SCS can be set by selecting HMI500 Settings/Communication/SCS Diff.

Nevertheless, the commands and signals of the REB500 system are modeled as far as possible on functions defined in the IEC recommendation. The functional scope of the station protocol is therefore reduced. The backup protection functions breaker failure, time-overcurrent and end fault that are optionally available with REB500 are also supported. According to the IEC recommendation, usage of the private range is only permitted with regard to the compatibility of existing devices. For this reason, additional REB500 functions that are not defined in the recommendation were implemented according to the future- oriented generic part of IEC 60870-5-103. REB500 also optionally provides a private range. Refer to IEC 60870-5-103 for an explanation of the various abbreviations. 4.2 General functions GUID-B95181CD-4E96-4569-BA0A-5D1EF56CA1D1 v2 The tables below define the functional scope of REB500 according IEC60870-5-103.

This is determined by the REB500 principle. The time stamp invalid bit (IV) in a disturbance record is always set, because the CIM module is unaware of the synchronization status at the instant of the record. The upload of disturbance data from the central unit is not possible via IEC60870-5-103. Creating an export file HMI500 provides facility for exporting the IEC 60870-5-103 communication data contained in the system database in the form of a text file (export file). To do this, select Tools/Export SCS data and IEC 60870-5-103 IBB and then click on the Export button. The application creates a text file (export file) iec103exp.lst, which contains all the information required. The file has the following structure: 1. Disturbance recorder signal configuration 2.

An entry is made in the table for every event configured using HMI500 or REBCON for transfer via IEC 60870-5-103. Since there can be more events per type (SPI or DPI) than the maximum number of entries a group can have (255), the system reserves additional groups as necessary. By this means, up to 1020 events per event type can be defined in the generic part. 1MRK 511 451-UEN B Section 4 IEC60870-5-103 Distributed busbar protection REB500 21 Communication protocol manual IEC60870-5-103 © Copyright 2019 ABB.

The input fields for REB500 signals covered by the public part of the standard (see Section 4.2) have a bright yellow background their default setting 0 for both IEC function type and information number. All other signals receive the presetting 0 for the IEC function type and the information number. A signal defined for protocol 60870-5-103 that is not in the public range and has 0 set for function type and information number is transmitted via the generic part of the protocol. A private IEC60870-5-103 definition can be entered for every REB500 signal in this dialog. The Set Default button is enabled for a signal in the public range of the protocol so that the ABB default setting can be restored at any time. The limitations specified in the standard must be observed when assigning information numbers. The latter must be within the following ranges: 16-52; 73; 128-130; 64-72; 74-93 Section 4 1MRK 511 451-UEN B IEC60870-5-103 26 Distributed busbar protection REB500 Communication protocol manual IEC60870-5-103 © Copyright 2019 ABB.

Figure 7: Private IEC 60870-5-103 definition Disturbance recorder, binary signal transfer Binary signals transmitted in disturbance records only have numbers and no designation. The assignment of numbers to signal names is given in the COMTRADE file filename.cfg, which can be uploaded, for example, from aBay Unit using HMI500. Signal configuration instructions Should the same logical signal be configured on two different BIO modules in a Bay Unit, only one of them should be relayed to the IEC 60870-5-103 bus. A configuration that is duplicated produces two indistinguishable events, which can cause some confusion. The response is reflected by HMI500, which also generates two events. Cause of transmission With the exception of 42 (generic writing command), all the possible causes of transmission are supported in the command direction. In the supervisory direction, they are all supported with the exception of 7 (test mode), 12 (local HMI) and 44 (return confirmation of a generic write command). Type identification The type identification defines the type of ASDU that has been transferred.

The timeout from the instant the upload command is issued to the receipt of the data varies in relation to the length of the disturbance record. The following applies: STP timeout <2.5 minutes per 1 second of disturbance record data (4I+4U, 2400 Hz). • Once the transfer of disturbance recorder data has started, the timeout changes to: Transfer timeout <1 Minute Section 4 1MRK 511 451-UEN B IEC60870-5-103 28 Distributed busbar protection REB500 Communication protocol manual IEC60870-5-103 © Copyright 2019 ABB.
