摘　　要：针对双馈风电场存在谐波污染问题,文中提出将具有谐振控制器功能的链式STATCOM应用于双馈风电场。分析了具有谐振控制器功能的链式STATCOM数学模型,然后对谐振控制器的控制特性进行改进,提出了一种具有低次谐波抑制作用的PIR-VPI混合控制方法。研究了该混合控制方法的工作原理,并建立数学模型,对参数进行设计,在MATLAB中进行验证。理论分析和仿真结果验证了此方案应用于双馈风电场中谐波抑制的有效性。Aiming at the problem of harmonic pollution in doubly-fed wind farms,this paper proposes to apply a chained STATCOM with a resonance controller function to doubly-fed wind farms.The mathematical model of the chained STATCOM with the function of the resonant controller is analyzed,and then,the control characteristics of the resonant controller are improved.A PIR-VPI hybrid control method with low harmonic suppression is proposed.The working principle of the hybrid control method is studied,and a mathematical model is established,and the parameters are designed and verified in MATLAB.Theoretical analysis and simulation results verify the effectiveness of the proposed scheme on harmonic suppression in doubly-fed wind farms.
