摘要
本文主要阐述基于MATLAB的微机母差保护仿真分析,通过建立母线差动保护模型及对差动电流和制动电流波形数据的分析,以此来判断故障时母线保护的动作情况,确保加入电网的微机母差保护装置安全稳定运行,使其更好地为电网服务.
This article mainly describes the simulation analysis of microcomputer bus differential protection based on MATLAB.By establishing a bus differential protection model and analyzing the differential current and braking current waveform data,the operation of the bus protection during a fault can be judged to ensure the connection to the grid The microcomputer mother differential protection device operates safely and stably,making it better serve the power grid.
