摘　　要：随着风力发电的大规模并网,风电场内的无功电压问题日益突出。将同步发电机组的励磁系统调差系数的概念引入风电机组的无功电压控制中,以提高风电场内部电压水平为目标,以发电机的安全运行极限和电网潮流为约束,以风电机组的附加调差系数为控制变量,建立了提高风电场内电压水平的风电机组附加调差系数优化整定模型,采用准蒙特卡洛方法,提出了风电机组附加调差系数优化设置策略。选取吉林地区某个含有58台DFIG的风电场进行分析。结果表明,对DFIG的附加调差系数进行合理整定可以充分发挥双馈风机的无功调节能力,有效改善风电场内部的电压波动。With wind power integration ,voltage and reactive power problems have become increasingly prominent. In this paper, voltage and reactive power control concept excitation system droop factor synchronous generators introduction of wind turbines in order to increase the wind farm internal voltage level as the goal, safe operating limits and grid tidal generator is bound to wind turbines additional droop factor control variables, the establishment of a wind farm voltage level to improve wind turbine attached droop coefficient optimization tuning model, quasi Monte Carlo method is proposed wind turbine attached droop factor optimization settings policy. Select an area containing 58 Jilin DFIG wind farm analysis. The results showed that the additional difference adjustment coefficient DFIG tuning can be reasonably full DFIG reactive power regulation, improve the wind farm internal voltage fluctuations. The experimental results show that the super capacitor energy storage system can achieve accurate and fast response to the side voltage is stable and the work efficiency is high. specified charging and discharging power, and the DC
