摘要
建立了风力发电机组和静止无功补偿器SVC的数学模型,并利用MATLAB/Simulink软件搭建了风电场接入电网后的仿真模型,针对风电系统中经常出现的联络线短路故障和风电场风速扰动,通过仿真计算表明,SVC不仅可以在常见的扰动下有效地提高风电场的稳定性,而且能够在快速的风速扰动下平滑风电场的有功功率输出,降低风电场对电网的冲击。
This paper builds a mathematic model of wind generator units and static var compensator （SVC）. According to the performance features of the wind turbine and SVC, a simulation model of the power system connected with wind farms is established by means of Matlab/Simulink. With respect to the short circuit fault in the grid and wind disturbances of the wind farm which often occur, the simulation results show that SVC can not only improve the transient stability of the wind power farm after short circuit of the grid, but also effectively smoothen the output of the wind farm and reduce impacts on the power system during the fast wind disturbance.
