摘　　要：在DIgSILENT软件中建立异步风电机组和双馈感应风电机组模型,以新疆某地区实际电网为例,分析比较了两种不同风机并网对电力系统电压和频率稳定的影响,同时,研究了两种风机并网前后对电力系统紧急控制策略的影响。仿真结果表明:当电网发生扰动时,双馈感应风机频率响应不明显;但在电网扰动影响电压稳定时,双馈感应电机能够提高一定的电压稳定性;当电网发生大扰动,采取紧急控制策略后电网的稳定性不如电网未接入风电时电网采取紧急控制策略后的稳定性。In DIgSILENT software in the wind generator set up asynchronous and doubly-fed induction wind generator model, with a certain area in Xinjiang actual network as an example, analyses and compares the two kinds of different fan grid to power system voltage and frequency of the influence of stability, and at the same time, two fan grid for power system before and after the effect of emergency control strategy. The simulation results show that happens in the power disturbances, doubly-fed induction fan frequency response is not obvious, But in the disturbance effect when the voltage stability, doubly-fed induction motor can improve certain voltage stability; When there is a major power grid disturbance, take emergency control strategy is not power grid stability when wind power grid access to take urgent control strategy of after stability.
