摘　　要：依据风电功率预测和地区系统无功优化运行方案,计算风电机组电气控制参考值,通过每台风电机控制器和变频器调节风电场注入系统的无功功率。提出了集成服务环境下风电场的无功调节策略,介绍了风电数据采集与监控(SCADA)系统的功率预测过程和参数整定过程。以基于双馈异步发电机的变速恒频风电机组为例,介绍了风电机组无功调节的实现方案。Based on the wind farm output forecasting and local electric network reactive power optimization results, the wind turbines electric control parameters are calculated as inputs to the reactive power controller. A reactive power regulation method based on application integration is proposed. The processes of power forecasting and parameter setting in the wind farm supervisory control and data acquisition （SCADA） system are discussed. The doubly fed induction generator （DFIG） wind turbine is used as an example to show how to adjust reactive power.
