The Choice Black Start Path of Shanxi Power Grid Using External Power Supply

The key to formulate black start of Shanxi power grid scheme is the choice of starting path,which usually need a great deal of calculation and analysis.This paper introduces the structure characteristics of Shanxi power grid,and gives the choice principle of black start path.In combination with Shanxi power grid structure,considering various controlled principles and current power gird operation,this paper gives the correct choice of starting path.
