Abstract
View of preventing cascading trips, this paper mainly studies the security level model of how to effectively prevent cascading failures in the system is studied. First of all, from the point of view of relay protection, we consider the case of backup protection for current protection, by judging the electrical distance between the operating parameters of the branch and the relay protection fixed value after the initial fault of the system, it can be judged whether the branch will undergo cascading trips or not. Then, considering the critical state of cascading trips in branch grids, a safety index is proposed to measure the shortest distance between the critical state of power grids and the current operation state, and the specific calculation method is given. Finally, an optimization model is given, which aims to find the nearest state on the boundary from the current operation state. Aiming at this model, this paper presents a solution method based on PSO algorithm, which is verified by simulation through an example analysis.
