摘要
根据济南电网的实际情况,就电网中大量存在的、小发电通过220kV、110kV或35kV变电站的35kV、10kV、6kV母线并网,及近两年出现的小发电经10KV开关站与系统并网的情况,以一典型实例介绍其并网线路整定计算所遵循的原则,以及整定计算中所遇到的一些特殊问题的处理办法。
Large numbers of small power stations having been merged into the main power grid through the bus of 35KV、10KV and 6KV in 220KV, 110KV or 35KV substations. These years, some small power stations are even merged into the main power grid through 10KV switching houses. According to this situation, based on the condition of Jinan Power Grid, combining several typical cases, the calculation principles and the methods of solving some special problems in relay protection setting are introduced.
