摘　　要：基于构网型控制的电网友好型风电机组具有黑启动、电网支撑和弱电网运行等优势,近年来逐渐被广泛研究。为探究不同电网友好型控制在不同场景下的运行性能,以全功率直驱风机为研究对象,总结归纳了4种典型的电网友好型风电机组控制策略。基于不同控制策略的架构和特点,在PSCAD/EMTDC仿真平台上搭建了相应电网友好型风电机组模型。分别在黑启动、风速变化、功率减载、频率支撑、电压支撑、故障恢复以及故障限流7种工况下探究不同控制策略的运行性能。最后,综合不同工况下的仿真结果,得到了总体性能最优的控制策略。Grid-friendly wind turbines based on grid forming control have been widely studied in recent years because of their advantages,such as black start,grid support and operational capability in a weak grid.To explore the operational performance of different grid-friendly control strategies in different scenarios,this paper takes a full power direct drive wind turbine as the research object and summarizes four typical grid-friendly control strategies.Based on the structures and characteristics of different control strategies,it builds the corresponding grid-friendly wind turbine models on PSCAD/EMTDC.Then,the operational performance of different control strategies is investigated in seven operating conditions,namely black start,wind speed change,load shedding,frequency support,voltage support,fault recovery and fault current limiting.Finally,the control strategy with optimal overall performance is obtained by synthesizing the simulation results in different conditions.
