7 Requirements for the data transmission of the differential protection Undisturbed and errorless telegram transmission through data link and data conversion Disturbances are supervised by the differential relays (percentage error/minute or error/hour). Alarm indication if error rate is to high. Total transmission delay over the wide area network < 5 ms Average delay time will be measured by the differential relay Transmission delay increases the tripping time Equal transmission delay in receive and transmit direction Unsymmetrical delay lead to a differential current Unsymmetrical delay forces a higher differential set point Use of external GPS-synchronization (PPS) with permanent asymmetry in the communication network (unwanted due to high effort and cost) Seite 7
8 Requirements for the data transmission of the differential protection Telegram reception with constant time difference Required max. ± 300 µs -> Higher value lead to Delay time jump indication in the operational log Due to delay time jitter the differential protection becomes insensitive through it s internal adaptive self restraint algorithm Distance for the communication link max. 500 km (311 miles) FO cable (single mode) and max. 15 network router between Keep total delay time < 5 ms for such a connection Seite 8

21 Tests for reduction of the delay time on the E1 - connection The jitter buffer is required to compensate delay time changes caused by the Ethernet network through stored and forwarded telegrams. Max. buffer time is a setting for the E1 interface of the router Default value 5 ms cause a delay time of 3,1 ms Successive reduction from 5 ms to 1 ms (minimal setting in the router) Protection device indicate no delay time jumps (precondition) Delay time reduced from 3,1 ms to 1,85 ms Transmission of used data slots of the E1 telegram (CESoPSN) 1 * 64 kb 32 * 64 kb Delay time reduced from 1,8 ms to1,4 ms Bandwidth reduction inside the Ethernet from 2 Mbit/s -> 500 kbit/s for the high priority Pseudo Wire connection with QoS Seite 21
