近年来，基于各种FACTS器件的电压源或电流源逆变器已被用于灵活的潮流控制、安全负载、阻尼电力系统振荡甚至风力发电的稳定。本文提出了一种基于电压源变换器（VSC） PWM技术的静态同步补偿器（STATCOM）来稳定并网风力发电系统。采用简单的STATCOM控制策略，只需要测量风力发电机终端的均方根电压。提出用模糊逻辑控制器代替传统的PI控制器作为STATCOM的控制方法。由于轴的建模对风力发电机组的暂态性能影响较大，因此也考虑了多质量轴模型。并将STATCOM连接WTGS的瞬态性能与螺距控制WTGS的瞬态性能进行了比较。对对称和非对称断层进行了分析。此外，还分析了STATCOM连接WTGS的稳态性能。据报道，STATCOM可以显著降低电压波动。最后，将STATCOM应用于一个多风力发电机的风电场模型。采用PSCAD/EMTDC对STATCOM连接的WTGS进行了仿真，并给出了综合结果来评估其性能。
Recently voltage-source or current-source inverter based various FACTS devices have been used for flexible power flow control, secure loading, damping of power system oscillation and even for the stabilization of wind energy generation. In this paper, we propose the static synchronous compensator (STATCOM) based on voltage source converter (VSC) PWM technique to stabilize grid connected wind generator system. A simple control strategy of STATCOM is adopted where only measurement of rms voltage at the wind generator terminal is needed. Fuzzy logic controller rather than conventional PI controller is proposed as the control methodology of STATCOM. Multi-mass shaft model of wind turbine generator system (WTGS) is also considered as shaft modeling has a big influence on the transient performance of WTGS. Transient performance of STATCOM connected WTGS is compared also with that of pitch controlled WTGS. Both symmetrical and unsymmetrical faults are analyzed. Moreover, the steady state performance of STATCOM connected WTGS is analyzed. It is reported that STATCOM can reduce the voltage fluctuation significantly. Finally STATCOM is applied to a wind park model with multiple wind generators. Comprehensive results are presented to assess the performance of STATCOM connected WTGS, where the simulations have been done by PSCAD/EMTDC.
