摘　　要：风电场风机多采用恒功率因数控制方式,在一定程度上对电压调整不利,存在电压波动较大的问题,由此可以看出风电场运行过程中存在的电压与功率因数不能同时兼顾的控制问题。提出了改进措施及建议,即电压-恒功率因数控制模式,对此控制方法进行了分析研究,并在某地区风电场进行了仿真研究,结果表明改进方法有效,减小了电压的波动,提高了电压合格率。Wind turbine mostly uses constant power factor control mode, but it＇s disadvantageous to voltage regulation to a certain extent and has higher voltage fluctuation problem, existing the control problem that voltage and power factor can~ be both taken into account during the operation of the wind farm. The improvement measure and recommendation that voltage-constant power factor control mode was proposed, and the control method was analyzed. The improved method was simulated in a particular area wind farm. The results show that the improved method is effective, reduces the voltage fluctuation and improves voltage qualification rate.
