N-2运行方式在宁夏电力通信业务中的应用

针对220 kV及以上线路保护、安稳等重要业务通道路由于关联性增加,无法满足运行要求的问题,对现有N-1通信网络运行方式进行分析,提出N-2通信网络路由运行方式安排,以确保安稳及保护等重要业务通道迂回路径的合理性。应用结果表明:N-2运行方式有效降低了宁夏电网安稳及保护通道运行风险,符合目前网络安全稳定运行要求。

Application of N-2 operation mode in Ningxia power communication service

Aiming at the problem of relevance increase of important business of protection, safety andstability channel route for 220 kV and above line in Ningxia power grid, analyzes present N- 1communication network operation mode, puts forward the arrangement of N-2 communication networkrouting operation to insure rationality of the protection and the safety and stability important businesschannel route. The application results show that N-2 operation mode effectively reduces the operationrisk of the protection and the safety and steady channel in Ningxia power grid, accords with thedemands of network safe and steady operation.
