Abstract: Abstract:The main connection of the Togtoh Power Generation Company Limited was introduced. Based on this, the risk factors of voltage outage on 500kV line caused by shutdown of all power units were analyzed. Starting from the viewpoints of frequency and voltage control and operation adjustment of the generator, the feasibility to provide the companywide auxiliary power system by one unit No.4 under condition of all the four output line tripout was discussed.
