摘要
结合云南电网220kV及以上电压等级的电网实际,介绍了云南电网主网继电保护的整定计算原则,探讨了线路保护、断路器保护、变压器保护和串补保护整定计算中的若干问题,供广大同行参考借鉴。
Protection is as the first defense line of safely and steadily and plays an important role in power system. Combining with the actual condition of Yunnan power grid 220 kV and above voltage level, the relay setting calculation principles in Yunnan main power grid are introduced, serval problems of setting calculation for line relays, circuit breaker relays, transformer relays and series compensation relays are discussed.
