摘　　要：本文从风电场低成本、高性能地满足电力系统要求的一次调频功能的角度出发,首次建立了含风电调频的电力系统频率响应模型,对实际制约风电场一次调频能力的非单机控制策略因素进行了分析,深度挖掘了风电场一次调频能力,提出了风电场一次调频直控风电机组技术方案,并将该技术方案在实际电力系统中进行了应用。现场实测结果表明,应用该技术方案的风电场可以高性能地实现一次调频,使风电可以作为优质的调频资源进行开发。以期通过该技术方案为电力系统安全稳定的运行提供支撑。In order to achieve low-cost and high-performance primary frequency control functions of wind farm that meet the requirements of the power system,the frequency response model of power system with wind power frequency control is established for the first time.The factors of non-single-machine control strategy that actually restrict the primary frequency control capability of the wind farm are analyzed.This paper gives the primary frequency control capability of wind farm under deep excavation and proposes the technical scheme of primary frequency control and direct control wind turbine of wind farm,which has been applied in the actual power system.Field test results show that,the wind farm applying this technical scheme can achieve primary frequency control with high performance,so that wind power can be developed as a high-quality frequency control resource.With a view to provide support for the safe and stable operation of the power system through this technical scheme.
