| 摘 要： | 在兆瓦级直驱型风力发电系统中,并网变流器控制是实现电能回馈电网的重要环节.针对采用LCL型滤波器结构的风力发电并网变流器在谐振频率附近的不稳定性、选择基于电容电压超前校正结合电网电压电流双前馈补偿间接控制变流器并网输出电流的控制策略.实验结果证明,采用该控制策略可以有效实现并网变流器稳定运行.抑制网侧输出电流谐波,同时具有较好的动静态性能.

| Abstract: | In MW wind power generation system,the control of voltage source grid-connected inverter is important for power transporting and energy converting.For grid-connected inverter with LCL filter,it makes system instability at resonance. A control strategy based on capacitance voltage lead emendation and grid voltage and grid current feed forward control is proposed.The stability and dynamical performance of grid-connected inverter is proved by the simulative results.The harmonic of grid current can be easily re... |
