Evaluation Index System for Power System Blackout Impacts and Its Application
To enhance blackout processing efficiency and accident analysis accuracy,this paper establishes the evaluation index system for blackout impacts and its supporting system in terms of the blackout range,users,duration and loss,etc.Determine the weight of each index by using AHP,and quantify each index at different levels by using fuzzy comprehensive evaluation method,and propose the concept to evaluate the size of a power outage which is called blackout impact factor.In the case study of a city power grid,the impacts of a specific blackout were evaluated by the constructed index system,and the subsequent repair and specific measures against the impact expansion were proposed,which verifies the practicality and effectiveness of the index system and its evaluation methods.
