摘要
本文针对新疆金风公司1.5MW直驱式永磁同步风力发电系统,采用多变流器并联的方式,应用基于电网电压定向的电压、电流双闭环矢量控制策略,实现并网逆变控制。仿真实验结果表明,采用该控制策略实现了独立调节系统输出的有功功率和无功功率,注入电网的电流为正弦波,馈入电网的谐波畸变率很小,且系统具有良好的动静态性能。
A high-performance grid converter is developed based on the direct-driven permanent magnet synchronous generators in the wind farm of Daban city of xinjiang province in the paper. Using double closed-loop vector control strategy of the voltage and current based on beamed grid voltage, the grid inverter control is carried out. The simulation experiment shows that the output active power and reactive power can be independently regulated, the feed-in grid current has the less rate of aberration of humorous, and the current of AC side is sine wave. The wind generator system has excellent dynamic and static performance.
