Normal process-related events can be viewed by the normal user with Event Viewer in PCM600. Critical system and IED security-related events are logged to a separate nonvolatile audit trail for the administrator. Audit trail is a chronological record of system activities that allows the reconstruction and examination of the sequence of events and changes in an event. Past user and process events can be examined and analyzed in a consistent method with the help of Event List and Event Viewer in PCM600. The IED stores 2048 system events to the nonvolatile audit trail. Additionally, 1024 process events are stored in a nonvolatile event list. Both the audit trail and event list work according to the FIFO principle. User audit trail is defined according to the selected set of requirements from IEEE The logging is based on predefined usernames or user categories. The user audit trail events are supported in IEC , PCM600, LHMI and WHMI.

Since only the administrator has the right to read audit trail, authorization must be properly configured in PCM600. The audit trail cannot be reset but PCM600 Event Viewer can filter data. Some of the audit trail events are interesting also as normal process events. To expose the audit trail events also as normal process events, define the level parameter via Configuration/Authorization/ Authority logging.

Operational information and controls are available through these protocols. However, some communication functionality, for example, horizontal communication between the IEDs, is only enabled by the IEC communication protocol. The IEC communication implementation supports all monitoring and control functions. Additionally, parameter settings, disturbance recordings and fault records can be accessed using the IEC protocol. Disturbance recordings are available to any Ethernet-based application in the standard COMTRADE file format. The IED can send and receive binary signals from other IEDs (so-called horizontal communication) using the IEC GOOSE profile, where the highest performance class with a total transmission time of 3 ms is supported. Furthermore, the IED supports sending and receiving of analog values using GOOSE messaging. The IED meets the GOOSE performance requirements for tripping applications in distribution substations, as defined by the IEC standard. The IED can simultaneously report events to five different clients on the station bus. The IED can support five simultaneous clients. If PCM600 reserves one client connection, only four client connections are left, for example, for IEC and Modbus. All communication connectors, except for the front port connector, are placed on integrated optional communication modules. The IED can be connected to Ethernetbased communication systems via the RJ-45 connector (100Base-TX) or the fibreoptic LC connector (100Base-FX). For the correct operation of redundant loop topology, it is essential that the external switches in the network support the RSTP protocol and that it is enabled in the switches. Otherwise, connecting the loop topology can cause problems to the network. The IED itself does not support link-down detection or RSTP. The ring recovery process is based on the aging of the MAC addresses, and the link-up/linkdown events can cause temporary breaks in communication. For a better performance of the self-healing loop, it is recommended that the external switch furthest from the IED loop is assigned as the root switch (bridge priority = 0) and the bridge priority increases towards the IED loop. The end links of the IED loop can be attached to the same external switch or to two adjacent external switches. A self-healing Ethernet ring requires a communication module with at least two Ethernet interfaces for all IEDs. RET615 21

If more than 30 IEDs are to be connected, it is recommended that the network is split into several rings with no more than 30 IEDs per ring. Each IED has a 50-μs store-and-forward delay, and to fullfill the performance requirements for fast horizontal communication, the ring size is limited to 30 IEDs Ethernet redundancy IEC specifies a network redundancy scheme that improves the system availability for substation communication. It is based on two complementary protocols defined in the IEC standard: parallel redundancy protocol PRP and high-availability seamless redundancy HSR protocol. Both the protocols rely on the duplication of all transmitted information via two Ethernet ports for one logical network connection. Therefore, both are able to overcome the failure of a link or switch with a zero-switchover time, thus fulfilling the stringent real-time requirements for the substation automation horizontal communication and time synchronization. PRP specifies that each device is connected in parallel to two local area networks. HSR applies the PRP principle to rings and to the rings of rings to achieve costeffective redundancy. Thus, each device incorporates a switch element that forwards frames from port to port. The HSR/PRP option is available for REF615, REM615, RET615 and REU RET615

29 1YHT530003D05 C Section 2 RET615 overview PRP Each PRP node, called a doubly attached node with PRP (DANP), is attached to two independent LANs operated in parallel. These parallel networks in PRP are called LAN A and LAN B. The networks are completely separated to ensure failure independence, and they can have different topologies. Both networks operate in parallel, thus providing zero-time recovery and continuous checking of redundancy to avoid communication failures. Non-PRP nodes, called singly attached nodes (SANs), are either attached to one network only (and can therefore communicate only with DANPs and SANs attached to the same network), or are attached through a redundancy box, a device that behaves like a DANP. COM600 SCADA Ethernet switch IEC PRP Ethernet switch REF615 REF620 RET620 REM620 REF615 GUID-334D26B1-C3BD-47B6-BD9D A5E9D V1 EN Figure 7: PRP solution In case a laptop or a PC workstation is connected as a non-prp node to one of the PRP networks, LAN A or LAN B, it is recommended to use a redundancy box device or an Ethernet switch with similar functionality between the PRP network and SAN to remove additional PRP information from the Ethernet frames. In some cases, default PC workstation adapters are not able to handle the maximum-length Ethernet frames with the PRP trailer. There are different alternative ways to connect a laptop or a workstation as SAN to a PRP network.

30 Section 2 RET615 overview 1YHT530003D05 C HSR HSR applies the PRP principle of parallel operation to a single ring, treating the two directions as two virtual LANs. For each frame sent, a node, DANH, sends two frames, one over each port. Both frames circulate in opposite directions over the ring and each node forwards the frames it receives, from one port to the other. When the originating node receives a frame sent to itself, it discards that to avoid loops; therefore, no ring protocol is needed. Individually attached nodes, SANs, such as laptops and printers, must be attached through a redundancy box that acts as a ring element. For example, a 615 series IED with HSR support can be used as a redundancy box. GUID A7-3AEC-42B2-BC4D-3083B V1 EN Figure 8: HSR solution 24 RET615

31 1YHT530003D05 C Section 3 Section Standard configurations RET615 is available in eight alternative standard configurations. The standard signal configuration can be altered by means of the graphical signal matrix or the graphical application functionality of the Protection and Control IED Manager PCM600. Further, the application configuration functionality of PCM600 supports the creation of multi-layer logic functions utilizing various logical elements including timers and flip-flops. By combining protection functions with logic function blocks the IED configuration can be adapted to user specific application requirements.

If the number of inputs and/or outputs in a standard configuration is not sufficient, it is possible either to modify the chosen IED standard configuration in order to release some binary inputs or binary outputs which have originally been configured for other purposes, or to integrate an external input/output module, for example RIO600, to the IED. The external I/O module s binary inputs and outputs of can be used for the less timecritical binary signals of the application. The integration enables releasing some initially reserved binary inputs and outputs of the IED s standard configuration. The suitability of the IED s binary outputs which have been selected for primary device control should be carefully verified, for example make and carry and breaking capacity. If the requirements for the primary device control circuit are not met, using external auxiliary relays should be considered. The IED has dynamic programmable LEDs. The presentation of the LEDs in this manual differs from the actual function blocks in the configurations. 28 RET615

Diagrams show the default functionality with simple symbol logics forming principle diagrams. The external connections to primary devices are also shown, stating the default connections to measuring transformers. The positive measuring direction of directional protection functions is towards the outgoing feeder. The functional diagrams are divided into sections with each section constituting one functional entity. The external connections are also divided into sections. Only the relevant connections for a particular functional entity are presented in each section. 38 RET615

45 1YHT530003D05 C Section 3 Protection function blocks are part of the functional diagram. They are identified based on their IEC name but the IEC based symbol and the ANSI function number are also included. Some function blocks, such as PHHPTOC, are used several times in the configuration. To separate the blocks from each other, the IEC name, IEC symbol and ANSI function number are appended with a running number, that is an instance number, from one upwards. If the block has no suffix after the IEC or ANSI symbol, the function block has been used, that is, instantiated, only once. The IED s internal functionality and the external connections are separated with a dashed line presenting the IED s physical casing. Signal Matrix and Application Configuration With Signal Matrix and Application Configuration in PCM600, it is possible to modify the standard configuration according to the actual needs. The IED is delivered from the factory with default connections described in the functional diagrams for binary inputs, binary outputs, function-to-function connections and alarm LEDs. The Signal Matrix is used for GOOSE signal input engineering and for making cross-references between the physical I/O signals and the function blocks. The Signal Matrix tool cannot be used for adding or removing function blocks, for example, GOOSE receive function blocks. The Application Configuration tool is used for these kind of operations. If a function block is removed with Application Configuration, the function related data disappears from the menus as well as from the data model, with the exception of some basic function blocks, which are mandatory and thus cannot be removed from the IED configuration by removing them from the Application Configuration. 3.4 Standard configuration A Applications The standard configuration includes three-phase transformer differential protection for two-winding transformers, numerical restricted earth-fault protection for the highvoltage (HV) side. The standard configuration is mainly intended for protection of the power transformer between current transformers. The IED with a standard configuration is delivered from the factory with default settings and parameters. The end-user flexibility for incoming, outgoing and internal signal designation within the IED enables this configuration to be further adapted to different primary circuit layouts and the related functionality needs by modifying the internal functionality using PCM600.
