中文摘要：

随着风电并网容量的增加，风电场应具备有功功率调节能力，能根据电网调度部门指令控制其有功功率输出。结合甘肃酒泉风电基地集群风电有功控制系统的实际需要，以实现最大风能利用、避免风电场频繁起停为目标，基于经典优先顺序法提出了一种应用于变速恒频风电场的限出力有功控制策略。针对风电场限出力控制需要，设计了风电场层有功功率控制框架及限出力控制流程，综合考虑场内风电机组的预测信息、运行状态与控制特性，建立了以风电机组调节性能指标为排序指标的风电场限出力控制序列，进而基于此控制序列，给出了风电场限出力有功分配方法。最后，通过算例验证了所提方法的正确性和有效性。

英文摘要：

With the rapid increase of grid-integrated capacity of wind farms, wind farms should possess the adjusting ability of active power that can control active power output of wind farm according to the command from control center of power grid. Combining with actual requirement for active power control system of clustered wind farms in Jiuquan wind power base in Gansu province, China, taking the utilization of wind energy farthest and the prevention of frequent start/stop of wind power generators as the objectives and based on classical priority list method, an output-restricted active power control strategy for wind farms composed of variable speed constant frequency （VSCF） wind power generators is proposed. To meet the demand on output- restricted control for wind farms, an active power control frame in the level of wind farm and corresponding output-restricted control process are designed. Overall considering the prediction information, operating conditions and control characteristics of wind power generation units within wind farms, an output-restricted active power control sequence for wind farms, in which the indices of control performances of wind power generation units are taken as the index for rank ordering, is established, and then, based on the control sequence the method to allocate output-restricted active power is given. The correctness and effectiveness of the proposed control strategy are verified by the calculation of a wind farm composed of 33 doubly fed induction generators.
