摘　　要：针对目前送端电压无功补偿能力不足、风电汇集地区内的风电场和机组无功补偿不同步以及风电机组和汇集站的控制方式不统一的现象,提出了一种无功控制策略——风电场群无功优化控制(wind farms cluster optimal reactive power control)。该控制方案依据当前的运行工况和先前的断面信息建立了多目标化的控制函数并进行了计算分析,从而实现了静态设备的调节和连续的动态补偿。通过仿真验证表明了无功优化控制在电压稳定性问题上的策略是可行的。At present, the reactive compensation ability of sending - end voltage is insufficient, the reactive compensation of wind farm and wind turbines in wind farm integration area is not synchronized, and the control mode for wind turbines and wind farm collecting stations is not uniform. In view of the above - mentioned situation, a reactive voltage control strategy is put forward, that is, wind farms cluster optimal reactive power control strategy. The control scheme establishes the multi - ob- jective control functions and carries out the calculation and analysis based on the current operating mode and the previous sec- tion information, therefore the adjustment of static equipment and continuous dynamic compensation are achieved. The simulation test shows the feasibility of optimal reactive compensation on voltage stability.
