摘要
由两相旋转坐标系下的数学模型,推导了得出了并网逆变器双闭环控制方法,并且对电流环的设计做了详细的介绍。根据控制原理在MATLAB环境下搭建了永磁直驱风力发电系统的仿真模型,进行了仿真实验。仿真结果表明,在风速变化的情况下,并网逆变器可以向电网输出稳定可靠的电能,系统稳态、暂态性能良好。
This two-phase rotating coordinate system mathematical model is derived and obtained dual loop inverter control methods,and the design of current loop made a detailed introduction.According to the control principle in the MATLAB environment to build a permanent magnet direct drive wind power system simulation model,the simulation experiments.Simulation results show that in the case of wind speed and inverter can output stable Aand reliable electricity grid,the system steady state and transient performance is good.
