摘　　要：利用PSASP软件的UPI接口程序模块,在PSASP中建立了双馈风电机组模型,以两个实际的地区电网为例,研究双馈风电机组接入地区电网后对电网电压的影响,结果表明:双馈风电机组提高了地区电网的静态电压水平;双馈风电机组在故障后能够减少系统所需的无功储备,从而有利于地区电网的电压稳定;风速的波动对地区电网的电压有影响,但一般不会影响其暂态稳定性。Doubly fed induction generator （DFIG） model is established by the utilization of user program interface （UPI） program interface module in power system analysis software package （PSASP） software environment. Taking two actual regional power grids as an example, the impact of DFIG integration on regional power grid is studied in this paper. Simulation results clearly indicate that DFIG can strengthen the steady voltage level of regional power grid, and can reduce the needed reserve of reactive power after faults occurred, which can improve the voltage stability of regional power grid, the fluctuation of wind speed will affect the voltage of regional power grid, but usually do not affect the transient stability.
