摘　　要：针对目前双馈风电系统控制参数选取时模型简化较多、PI控制器参数整定困难等问题,建立了双馈风电系统在两相同步旋转坐标系下的数学模型。按照网侧电压外环PI参数、电流内环PI参数、机侧电流环PI参数的顺序依次确定3组PI参数,并在求一组参数时考虑前面已确定参数对此参数的影响,提出了一种相互协调的PI参数优化设计方法。在RTDS实时仿真系统中对双馈机组的稳态、暂态响应特性进行仿真分析,结果表明该方法在稳态、暂态下的跟随性与抗扰动性等控制指标性能良好。In the light of the problems in parameter selection of doubly-fed wind power system, such as simplified model ＆ difficult parameter setting of PI controller, the mathematical model of two-phase synchronous rotating coordinate system is set up. 3 set of PI parameters are determined as per the sequence of outer voltage loop, inner current loop, generator current loop, and considering the influence of identified parameters. The PI parameter optimal design method of mutual coordination is proposed. The steady ＆ transient response characteristics of doubly-fed wind power unit are simulated in RTDS real-time simulation system. It is shown that the following performance ＆ disturbance rejection are good under steady and transient state.
