随着连接电网的风力发电机（wtg）数量的增加，系统运营商可能会要求它们参与频率控制，以防系统上产生和消耗的电力突然不平衡。本文研究了永磁同步发电机（PMSG）的全变流器变速风力发电机组（FCWTG）的频率响应能力。提出了一种提高频率控制性能的控制方案，说明了FCWTG初始有功输出的重要性。提出了一种谨慎终止风电场频率支持的方法，并进行了仿真。由此产生的频率控制性能优于传统的同步发电机。
With an increased number of wind turbine generators (WTGs) connected to an electricity network the system operator may request that they participate in frequency control in the event of a sudden unbalancing of power generated and consumed on the system. In this paper the frequency response capability of the full converter variable speed wind turbine generator (FCWTG) with permanent magnet synchronous generator (PMSG) is investigated. A control scheme is developed that improves the frequency control performance, illustrating the importance of the initial active power output of the FCWTG. A method of carefully ending the frequency support of a wind farm is proposed and simulated. The resulting frequency control performance compares favorably to that of a conventional synchronous generator plant.
