Analysis and Application of Evaluation System for Power Grid Operation Safety

According to the analysis of the safety of power grid operation in China,this paper puts forward a simple and practical index system of power grid operation safety evaluation which includes structural safety,operation safety,reliability and abundance.Then the extreme value method,the coefficient of variation method,and the integrated linear scoring method were used in this paper to establish evaluation model which evaluates the safety of power grid operation and some examples were analyzed and applied.
