With the rapid development of China's power grid and intelligent power grid construction, can set up a scientific evaluation index system of evaluation of regional power grid operation mode and methods, to improve the safety and reliability of the power grid operation in power grid operation efficiency, flexibility and ease of has important theoretical and realistic significance. According to the regional power grid operation characteristics, combined with the actual demand of power department, put forward the evaluation index system of district power grid operation mode, including the power supply reliability, power quality, economy, short circuit current, operation complexity and maintenance method characteristics evaluation in seven aspects, and gives its calculation method, introducing the basic idea of analytic hierarchy process (ahp) and fuzzy membership function, realize the quantitative indicators, using data envelopment method and fuzzy comprehensive evaluation method for comprehensive evaluation. Finally will this paper the proposed regional power grid operation evaluation index system and evaluation method is applied to calculation of a practical substation, verify the effectiveness of the proposed method.
