摘要
地方小水电网由于网络结构复杂,运行方式变化频繁,对继电保护的正确动作带来了很大的影响。根据地区电网多年运行的情况,对保护的整定计算方法等提出了一些改进措施和建议。
The regional small hydropower grid is complicated in network structure and its operation pettern varies very frequently. These situations exert a great influence on corrective actions of relay protective devices. In this paper, bosed on the operation situations of the regional electric grid in many years, some measures and suggestions for improving setting calculation method of relay protection are prasented.
