[Abstract]:The smart distribution network is moving towards gridding, the topology structure of multi-source is developing, the traditional distribution network protection and feeder automation (FAA) have become more and more difficult to meet the demand of smart distribution network self-healing. Current differential protection is widely used in transmission lines due to its superior rapidity, sensitivity and selectivity. The existing methods are realized by using special optical fiber channel or multiplexing channel based on synchronous digital series / quasi synchronous digital series SDH / PDH technology, but these communication equipments are expensive and slow to set up. In this paper, a differential protection device for smart distribution network is proposed and developed. The device is based on Ethernet passive optical network (EPON) to realize the transmission of sampled data between the differential protection devices, coupled with anti-delay jitter and IEEE 1588 synchronization algorithm. Multi-terminal line differential protection is realized. The test shows that the protection can move accurately and meet the requirements of precision and action time. The device has been used in a 10 kV transmission line.
