摘要
将统一潮流控制器用于风力发电系统,通过统一潮流控制器优秀的潮流调节功能,对风力发电系统中的功率调节进行有效改善,与传统风电直接接入电网时带来的谐波污染相比,统一潮流控制器的使用能给风力发电注入电力系统的谐波污染带来很大抑制作用,使得系统的功率补偿得到进一步优化。另外,对统一潮流控制器串联侧采用预测控制策略,使得系统的动静态性能有了很大提高,同时降低了控制器的复杂性,有利于EMI滤波器的数字化实现。通过Matlab仿真试验验证了以上策略的有效性和可行性,具有一定应用价值。
The unified power flow controller （UPFC） is applied to the wind power generation system. The power regulation performance of the wind power generation system is improved effectively by means of the excellent power flow regulation function of the UPFC. In comparison with the harmonic pollution when the traditional wind power generation is accessed into the power grid directly, the UPFC can restrain the harmonic pollution when the wind power generation is injected into the electric power system, and optimize the system power compensation further. The predictive control strategy is adopted in the series side of the UPFC to improve the static and dynamic performances of the system greatly, reduce the complexity of the controller, and is beneficial to the digital implementation of the EMI filter. The effectiveness and feasibility of the above strategy were verified with Matlab simulation experiment, and the scheme has a certain application value.
