中文摘要：
风能存在随机性，大规模风电并网后会引起附近电网电压波动，风况、风电机组特性和电网状况会对风电引起的电压波动与闪变有影响。文章从风能和风力发电机组特性出发，建立了含风电机组的电网仿真模型，基于Matlab／Simulink搭建了仿真模型，研究了风电场所接入电网状况对风电引起的电压波动与闪变的影响。算例结果表明，系统短路容量和线路电抗与电阻比等对风电场的电压波动与闪变有较大的影响，通过选取合适的并网点和电压等级、合适的线路电抗与电阻比，能够有效抑制风电引起的电压波动与闪变。
英文摘要：
Due to the randomicity of wind power energy, the voltage fluctuation of power grid will occur after large-scale wind farms are connected with power grid. The factors such as wind regime, characteristics of wind power generators and system condition of power gird impact the voltage fluctuation and flicker caused by wind power generation. Based on the features of wind power and characteristics of wind power generators, a simulation model of power grid in which the wind power generation units are included is built. With the model set up on the platform of Matlab/Simulink, the impacts of states by which the wind farm is connected with power grid on voltage fluctuation and flicker caused by wind power are researched. Case study results show that there are relatively great impacts of system short circuit capacity and the ratio of line reactance to line resistance on voltage fluctuation and flicker caused by wind power, thus by means of choosing appropriate voltage class and location where the wind farm is connected with power grid as well as choosing appropriate ratio of line reactance to line resistance the voltage fluctuation and flicker caused by wind power can be effectively suppressed.
