Project Evaluation Method for Secondary System Based on FTA
In order to reduce the overall level of the power secondary system security risks,and realize the efficient operation of smart grid,the post-project evaluation of power secondary system is studied.This paper summarizes various influencing factors of the secondary system reliability from the secondary equipment,automation system and communication system respectively,as well as the function mode of each factor and their influence on the primary system;then it establishes the post-project reliability evaluation index system.thereupon,overall evaluation is researched,formulates the fault tree graph of relay protection system,and finally proposes the evaluation method based on fault tree analysis (FTA) and dynamic fault tree analysis (DTA).
