| 摘 要： | 在大功率风力发电系统中,并网逆变器控制是实现电能转换与传输的重要环节。针对采用T型滤波器结构的风力发电并网逆变器,提出基于桥臂电流闭环结合前馈补偿间接控制逆变器并网输出电流的控制策略,并根据三相电压源型并网逆变器开关函数的数学模型进行了控制系统仿真研究。仿真实验结果证明采用该控制策略提高了并网逆变器的稳定性和动态性能,同时可以有效抑制并网节点输出电流中的电流谐波。

| Abstract: | In high-power wind power generation system,the control of voltage source grid-connected inverter is the key for power transporting and energy converting.For grid-connected inverter with T filter,a control strategy based on current of bridge arm and feed forward control was proposed.Then grid-connected inverter control system model combined switch function was set up.The simulation results testify that the stability and dynamical performance of grid-connected inverter are proved with proposed control strategy.The harmonic of grid current can be easily reduced by T filter. |
