Abstract :
Many severe cases of black outs have taken place recently among different countries, which has been the significant factor on power system´s safe and stable operation. Taking 2015 Yunnan-Guangdong ultra-high voltage AC/DC transmission system as example, power flow diversion is analyzed when faults occur on the sending Yunnan power system. Action of phase-to-phase resistance three segment protection is obtained by comparing calculating resistance and protection setting, which provides reference that how to prevent the cascading outage of Yunnan power grid in the planning of 2015 Yunnan-Guangdong ultra-high voltage AC/DC transmission system.
