摘要

针对大规模风电场接入电网带来的电压无功问题，给出了双馈风电机组的功率关系，总结了双馈风电机组固有无功调节容量研究成果。分析了双馈风电机组的功角特性及静态稳定约束对双馈风电机组无功调节容量的影响，简述了电网导则可能对双馈风电机组无功调节容量的约束。在此基础之上，分析了综合考虑机组自身运行约束、静态稳定裕度和电网导则约束的双馈风电机组无功调节容量。利用实际机组参数进行仿真，结果表明，综合考虑多种约束条件能够使双馈风电机组的无功调节容量分析更接近实际情况，为双馈风电机组参与风电接入地区电网电压的调节提供理论依据。

Abstract

For voltage issue caused by large-scale wind farm integration into grid， this paper introduces the power relationship of doubly-fed induction generator（DFIG） and summarizes the research results on the inherent reactive power capability of DFIG. The power-angle characteristic of DFIG and the impacts of static stability constraint and grid code on the reactive power regulation of DFIG are analyzed. Based on these， reactive power regulation capability of DFIG with constraints， such as operation limit， static stability， and grid code， is analyzed. By simulation of actual DFIG， it is shown that the reactive power regulation capability of DFIG considering multi-constraints is closer to the actual. Also， it can help DFIG take part in the grid voltage regulation in wind power integrated region according to accurate reactive power regulation capability of DFIG.
