鉴于大规模风电并网的集中控制和精细化调度要求，文中基于区域有功功率分层调度思想，设计了风电调度中心站-风电集群控制主站-风电场控制执行站3层体系架构的风电集群有功功率控制系统，并给出风电集群控制主站和各场站间控制接口的设计方案。继而考虑风电场、分散接入风电机组的调节性能差异，针对运行实际需求提出一套面向集群控制主站的有功功率控制策略，实现风电场有功控制模式的在线决策和相应模式下的有功功率指令值的在线快速计算，并验证了控制策略的有效性。所建系统可实现风电集群内风电场、分散机组的统一调度与监控，并且在充分利用电网接纳风电能力的同时提高集群运行的经济性，有效解决目前风电分散控制导致的资源浪费、协调困难等问题。

According to the demand of centralized control and elaborated dispatch of large-scale wind power integrated to the power grid,an active power control system for the wind farm cluster is designed based on the hierarchical dispatch of regional active powers.The system adopting a three-tier structure is subdivided into the wind power dispatch station,wind farm cluster control station and wind farm execution station.The designed scheme of interface between the master control station and wind farms in the wind farm cluster is presented.Taking the regulation performance differences of various wind farms and scattered wind turbines into account,an active power control strategy for the master control station in the wind farm cluster is then proposed to realizing online decision-making of active power control mode for wind farms and fast online calculation of active power instruction values under corresponding modes.The validity of the control strategy has been proven through simulation. The result shows that the system can realize unified dispatch and monitoring of wind farms and scattered wind turbines in the cluster.It can also make full use of the wind power acceptability while improving the economical efficiency of cluster operation. The system can effectively solve the problem of resource wasting and coordination difficulty resulting from the existing scattered control of wind farms.
