摘要
为了解决风力发电的分散性和波动性以及接入电网对电力系统造成冲击等问题,提高整个系统的电压频率稳定性[1],文章以DSP作为主控制器,研究设计了一种基于双PWM控制的风电并网换流器。针对风力发电并网换流器的主电路,设计了整流和逆变部分的双PWM电路拓扑结构,从而提高了系统的动态响应,减少了损耗和冲击,实现了电能的双向传输,同时还能提高风力发电机侧功率因数。最后对设计的系统进行仿真验证。
In order to solve the issues such as the dispersion and fluctuation features of wind power generation and the impaction of grid connection on power system, so as to improve the voltage frequency stability of the system, a wind power parallel-in inverter based on double PWM control with DSP as the main controller is designed. For the main circuit of the wind power parallel-in inverter, the double PWM circuil topology structure of rectifier and inverter parts is designed, so as to enhance the dynamic response of the system, reduce the loss and impact, realize the two-way transmission of electrical energy, but also can improve the power factor in the wind generator side. Finally the designed system is undergone simulation verification.
