摘要
结合青海串补一期工程的建设,理论分析了串补接入后电容器不平衡运行情况下系统电气特征,构建单侧单相串补旁路、单侧两相串补旁路以及两侧单相串补旁路等多种典型情况下的复合序网图,阐明不同运行模式下继电保护相关元件所受的影响,提出相关的运行整定建议。
The electrical feature of capacitor at unbalance operation condition after connecting series compensation is analyzed theoretically with combination of the first phase construction of Qinghai series compensation,the composite sequence network diagram at such multiple typical conditions as single side single phase serial compensation bypass,single side two phase series compensation bypass and two sides single phase series compensation bypass are set up,the influence of relay protection elements is described and the related suggestions for operation and setting suggestions are proposed.
