摘要
根据风电机组在风电场中的位置的不同,建立反映不同风速变化的异步发电机风电场模型,将风电场接入简化的电力系统模型,对风电场风速变化时风力机的稳态运行以及部分机组出口发生相间短路故障的机组运行情况进行了仿真。仿真结果表明,异步风力发电机向系统发出有功的同时,需要从系统吸收一定的无功功率,适当的无功补偿有利于提高电压水平和风电场并网运行能力。
Considering the location difference,wind power plant model with asynchronous wind driven generators is set up.After connecting the wind power plant to a simplified power system,a simulation research to test the steady operation of wind driven generator in wind speed variation and the outlet phase fault of partial wind driven generators is established.The results suggest that asynchronous wind power generators will absorb reactive power when supplying active power and reactive power compensation will improve voltage profile and the stability of grid-connected wind power plant.
