DFIG_变流器为电压源_包含轴系模型_先打开坐标库

关于20kV的两端柔性直流系统的建模仿真及其分析( Modeling and Simulation of flexible DC system on 20kV and its analysis)

说明：  里面通过MATALB中的simulink进行保护的构建，并利用编程的方法进行继电保护的构建(It uses Simulink in MATALB to construct the protection, and uses the programming method to construct the relay protection)

说明：  双馈式风力发电机simulink建模，对初学者很有帮助，对风力发电进行模拟(Modeling of doubly-fed wind turbine simulink)
