13 1MRK UEN Section 2 Interbay bus functions Section 2 Interbay bus functions 2.1 Introduction 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 confer to 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 IEC However Section 2 of this document also contains information of a second IBB using IEC if configured. 2.2 Basic configuration The dialog for configuring the communication is accessed by selecting Communication in the HMI500 Configuration menu.

17 1MRK UEN Section 2 Interbay bus functions 2.3 Configuring IEC IBB For IEC all important signals are mapped automatically to the Model (see Section 3.3 Mapping of the REB500 signals to logical nodes ). This is done by the HMI500 tool automatically and can t be changed manually. This is shown by an inactive tick checkbox for IBB 1 or IBB 2 respectively. The logical Node and the name of the data attribute of a mapped signal are shown in the IEC box. The IEC box is not shown for signals which are not transferred to the SCS/SMS. Figure 6 Configuring signals as events Diagnostic and system events are always available for transfer whichever protocol is in use and cannot be configured. The IEC section only appears when the protocol is configured. Communication Protocol Manual, IEC

18 Section 2 Interbay bus functions 1MRK UEN Logical node GGIO (Generic process I/O) configuration Signals which are not mapped to the IEC Model by the HMI500 tool automatically can only be transferred to SCS/SMS indirectly. They have to be assigned to binary I/O s first. The binary I/O s are represented by the logical node GGIO in the Model. By default no signals are mapped to the GGIO logical node. The mapping configuration is opened by selecting the CR channel and pressing button CR event config, OC channel and OC event config for binary inputs respectively.

21 1MRK UEN Section 2 Interbay bus functions To stabilize the display during normal operation, differential currents below the zero limit (dead band) count as zero and are transferred as such. Providing the condition for transmitting a current value is fulfilled, all the differential currents 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 thresholddelta a new event will be sent with thecurrent value. If this value is below thedeadband threshold, the value 0 will be sent instead Configuring the SCS differential current parameter The precise conditions for sending differential currents to the SCS can be set by selecting HMI500 Settings / Communication / SCS Diff. current parameters. Figure 11 Settings / Communication / SCS Diff. Current Parameters Communication Protocol Manual, IEC

22 Section 2 Interbay bus functions 1MRK UEN Settings in this dialog are made for each busbar section (bus zone) and can be changed after activating the respective field. The differential current parameters are as follows: Table 5 SCS Differential Current Parameters Item Description Min. Max. Default Step Unit Update period Enabled Delta L1_L2_L3 Dead band L1_L2_L3 Determines how often the differential current measurement has to be updated. Enables polling of the bus zone differential currents. Applies to all bus zones. Delta per bus zone for phases L1, L2 and L3. Dead band per bus zone for phases L1, L2 and L s yes no Yes A A Delta L0 Delta per bus zone for the neutral current L A Dead band L0 Dead Band per bus zone for the neutral current L A Delta and Dead band settings that are too low result in a high data load on the bus. For this reason, care should be taken to set reasonable values. 14 Communication Protocol Manual, IEC 61850

23 1MRK UEN Section 3 IEC Section 3 IEC Introduction The REB500 can be integrated into a station network confirming to the IEC The IEC configuration is largely automatic. The event signals need to be configured in order that they can be transmitted over the IEC protocol. The allocation of signals to the IEC is done automatically, and is exported as SCD file. In message transmission, all the REB500 signals are provided via the IEC In the ideal case these are allocated to the predefined logic nodes, however, if this is not the case they can be transmitted as generic data (GGIO). In command direction, resetting of LEDs, trip relays and disturbance recorder data is possible. REB500 supports the transfer of disturbance records according to IEC as compressed COMTRADE format. 3.2 Modeling in logical devices REB500/REB500sys utilizes a physical IEC connector for the complete REB500 system. All logical nodes are assigned to logical devices. All REB500 bay units, as well as the central unit are defined as a logical device. The designation of the logical device are based on the associated ABB reference for the bay or central unit and the REB500 Name 3.3 Mapping of the REB500 signals to logical nodes The REB500 signals are associated with the logical nodes of the IEC model. The mapping of the signals to the logical nodes is shown in the following table. Communication Protocol Manual, IEC

26 Section 3 IEC MRK UEN To ensure that a signal is correctly transmitted via IEC it must be configured and allocated as an event to the IEC interface. Signals that are not in the above table can be configured as events for IEC They will be transmitted as GGIO data. By pressing the button "Generate I/O Signals" the output signals that are relevant for are configured with an appropriate event configuration. This configuration is made for the station protection functions (busbar protection, breaker failure protection, pole discrepancy, overcurrent, and end fault protection) if the signals are not already configured. 3.4 Differential currents The differential currents are available for each bus zone in the logical nodes PDIF. They are assigned in the central unit s logical device. The parameters to be transmitted have to be configured in the menu SCS differential current parameter.

27 1MRK UEN Section 3 IEC The disturbance records are read out of the bay units with the MMS file transfer protocol. The records are available in zipped COMTRADE format in the following directory: LD/ID/COMTRADE/ disturbance file name Table 9 Disturbance file directory Item LD ID disturbance file name Description Logical device Identification of the logical device For name format see Operation Manual 3.6 User activity events IEC contains for security related definitions a logical node GSAL allowing supervision of security related actions. For detailed mapping see Cyber security guideline 1MRK UEN. 3.7 Creation of the *.IID file All the IEC relevant data can be exported in IID format for further processing with IEC conformant system configuration tools (see Operation Manual). 3.8 Redundant interbay bus REB500 uses the IEC standardized Parallel Redundancy Protocol (PRP). The redundant line supervision is mapped to the signals PRP LineA ready and PRP LineB ready, which can be used as binary output signals and as signals of the event list, or for the LED signalization of the local HMI. Both supervision signals (if configured) are automatically mapped to the logical node LCCH (Data objects ChLiv and RedChLiv) which can be used for supervision of the redundant lines. Moreover, PRP error rate counters for both lines are also mapped to the logical node LCCH (Data objects FerCh and RedFerCh). Communication Protocol Manual, IEC
