Abstract

The invention provides a reliability evaluation and correlation analysis method and system for power system protection, reliability evaluation is carried out on a protection device from two levels of an equipment level and a system level, and on the basis of reliability evaluation, performance influence factors of historical data and operation data on protection are utilized, so that the reliability evaluation and correlation analysis of power system protection are realized. And correlation analysis is carried out on the influence on the system, so that the controllability, stability and decision of the power system are facilitated.

Description

technical field [0001] The invention belongs to the technical field of power system analysis, and in particular relates to a reliability evaluation and correlation analysis method and system for power system protection. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] With the increase of electricity demand, the stable operation of the power system is becoming more and more important, and the protection of the power system also needs to be more complete. Power grid protection is essentially a system, and the boundary determination of the protection system should follow a basic principle, that is, the combination of basic functional modules that complete the protection function for the primary elements of the power system. [0004] According to the knowledge of the inventors, the current stable operation analysis of the power system is most...
