摘　　要：在分析传统发电机组和风电机组的调频能力基础上,提出一种以整个风电场作对象的新型风电场调频控制策略,该策略基于分层架构,通过储备控制,既能在开始几秒钟提供快速有功功率支持,帮助水力发电为主的系统减少初始频率下降,在一定风速下,也能长期提供额外有功功率支持;仿真结果表明风电场能够在一定程度上像常规电厂一样参与系统频率控制。Based on the analysis of frequency regulation capability of traditional generator and wind turbines generator,a new frequency control strategy based on hierarchical structure is proposed with the whole wind farms as object.Through the reserve control of wind farms,this strategy can provide the short-term extra active power support which will help to reduce the initial frequency fall for a hydro dominated system,and will provide a long-term additional active power under a certain wind speed.Simulation results indicated that wind farms can participate in frequency control like conventional power plants to a certain extent.
