摘　　要：风电是间歇性电源且常和电力电子装置一起接入电力系统.因此,风电场的接入有可能影响原系统的可靠性、稳定性和电能质量.随着风电机组单机容量和风电场规模的增大,风能的随机性、间歇性和不可调度性的缺点使其并网后对电力系统的影响也越来越明显.风电功率的注入将改变当地电网的潮流分布,引起局部电网的节点电压产生波动,而且大规模风电的接入会对系统的功角暂态稳定性产生影响.利用Matlab/Simulink软件进行仿真,将定风速风电机组接入三机九节点的经典模型,仿真分析风电并网后对系统暂态稳定性的影响.The wind power is intermittent,and often with power electronic devices connected to the system.Therefore,wind farm access has an impact on the operation of the power system,is likely to affect the original system reliability,stability,and power quality.As the wind unit capacity and the increasing scale of wind farm,wind power randomness,the disadvantages of intermittent and scheduling sex makes it after the interconnection influence on power system is becoming more and more obvious.Injection of wind power will change the tide of the local power grid distribution,cause local grid node voltage fluctuations;and large scale wind power access will affect the power-angle transient stability of the system.Using Matlab/Simulink software simulation,with wind turbines in the three-machine nine nodes classical model,the simulation analysis of wind power access grid after effect on system transient stability,is made.
