摘　　要：对双馈异步风电机组采用恒功率因数控制模式和恒电压控制模式时,风电场的并网特性不同影响进行研究。根据双馈异步风电机组数学模型,分析不同运行模式对系统静态稳定和暂态稳定的影响及无功电压支撑能力;通过实例仿真并分析了在2种不同模式下场网两侧的电压、功率等指标的变化情况,认为双馈异步风电机组风电场采用恒电压控制模式运行时,其稳定性优于恒功率因数控制模式,同时有利于提高风电场的可用率和发电量。This paper studies the interaction between different control modes and the power grid of variable speed constant frequency wind turbines,establishes a mathematical model of doubly fed wind turbine,studies the operating mechanism of wind farms using constant power factor control and constant voltage control,and analyzes the influence of static stability and transient stability of different operating modes.By simulating the change curve of voltage and power on both sides of the field network,it is concluded that the stability of the double fed wind electric field with constant voltage control mode is better than the constant power factor control mode,and it is also more beneficial to improve the availability and generating capacity of the wind farm.
