高渗透率并网风力发电的谐波特点及其抑制研究
|
摘要
为了研究分布式、高渗透率风电并网给电网带来的谐波问题,本文理论研究了直驱风力发电系统以及双馈风力发电系统的谐波特点,得出直驱风力发电系统的总电流谐波畸变率不变及双馈风力发电系统的谐波电流有效值不变的特点,利用实测系统验证了该结论的正确性,并针对风力发电的主要谐波给出了抑制方法。最后提出了适用于谐波分析的直驱风力发电系统以及双馈风力发电系统的简化等效模型,该模型可用于大规模的高渗透率并网风力发电的谐波研究。
In order to study the harmonic problem caused by distributed and high-permeability wind power in the power grid,this paper studies the harmonic characteristics of the directdriven wind power generation system and the doubly-fed wind power generation system, concluding that the total current harmonic distortion rate of the direct-driven wind power generation system is constant while the effective value to the harmonic current of the doubly-fed wind power generation system is constant. The correctness of the above conclusion is verified by an actual measurement system,and the suppression method is provided for the main harmonics of wind power generation.Finally,a simplified equivalent model of the direct-drive wind power generation system and the doubly-fed wind power generation system suitable for harmonic analysis is proposed. The model can be used for the harmonic research of large-scale high-permeability grid-connected wind power generation.
