| Abstract: | 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. |
