Research On Power Supply Reliability Evaluation Of Huizhou Power Grid Based On Analytic Hierarchy Process

It is an important task for power system to evaluate the reliability of power supply and excavate the existing problems in reliability so as to provide guidance for the operation planning and development of power system.Aiming at the comprehensive evaluation of power supply reliability of power grid,this paper takes Huizhou power grid as the research object and establishes an evaluation model based on analytic hierarchy process(AHP).The main research contents are as follows:1.Considering the actual operation of power grid,a hierarchical model for power supply reliability evaluation is established based on the analytic hierarchy process(AHP)evaluation theory.The weight of each index is determined by expert scoring method,and the analytic hierarchy process model of all factors is established.2.Taking Huizhou power grid as the research object,an engineering example is analyzed.The power supply reliability of each district is analyzed and studied to provide data basis for the evaluation of AHP.Then,by using the analytic hierarchy process(AHP)model,the power supply reliability of each administrative region is scored and compared,and the existing problems in the power supply reliability of Huizhou power grid are excavated based on the evaluation results and engineering practice,so as to provide support for further improvement of power supply reliability.3.Based on the evaluation results of analytic hierarchy process(AHP),specific engineering measures are proposed for Huizhou power grid in terms of basic management,planning and construction,operation analysis and technical improvement.Taking Huizhou power grid as an example,this paper makes a concrete analysis to verify the rationality and scientificity of the evaluation system proposed in this paper.
