自己搭建的继电保护中的变压器比率制动保护模型，对研究变压器的保护有一定的参考价值(Build their own protection transformer protection ratio brake model, transformers for protection of some reference value)

MATPOWER is a package of free, open-source Matlab-language M-files for solving steady-state power system simulation and optimization problems, such as: power flow (PF), continuation power flow (CPF), extensible optimal power flow (OPF), unit commitment (UC) and stochastic, secure multi-interval OPF/UC. It is intended as a simulation tool for researchers and educators that is easy to use and modify. MATPOWER is designed to give the best performance possible while keeping the code simple to understand and modify.
