Ether CAT控制分站在井下短路保护中的应用

Application of Ether CAT Control Substation in Underground Short Circuit Protection

摘要: 提出了一种基于Ether CAT分站的井下短路保护系统,主要由Ether CAT分站、具有Ether CAT通讯接口和联锁接口的综合保护装置等构成。Ether CAT分站支持Ether CAT与光纤联锁通讯，Ether CAT与光纤联锁网协同工作并互为后备，当一种网络因故障中断时，后备网络独立实现短路保护选择性功能。系统实现了井下短路保护的选择性，并能够迅速确定故障点位置，缩短故障排查时间，提高了供电网的安全性与可靠性。

Abstract: In the article, we proposed a underground short circuit protection system based on Ether CAT substation, which mainly composed of Ether CAT substation and integrated protection device with Ether CAT communication interface and interlock interface. The Ether CAT substation supports Ether CAT and fiber interlock communication mode. Ethernet Ether CAT and optical fiber interlock network can cooperate with each other, when one is interrupted by the failure, the other network can complete the work of system independently. The system can achieve short circuit protection selectivity, determine the position of fault quickly, shorten troubleshooting time and improve safety and reliability of power grid system.
