考虑风电场暂态电压稳定的无功控制策略

Reactive Power Control Strategy Considering Transient Voltage Stability of Wind Farms

基于哈密地区风电场内无功设备的动态补偿和物理分布特性,提出了一种综合考虑动态无功补偿设备和双馈风力发电机组协调控制无功出力的集群风电场暂态电压稳定的控制策略。算例分析的仿真结果表明,所提的无功暂态控制策略在满足风电场接入并网点暂态电压稳定的同时,能使得无功补偿设备补偿无功裕度更大,集电线上各风机的机端暂态电压裕度更均衡。

In this paper,a kind of control strategy for the transient voltage stability of cluster wind farm is proposed based on the comprehensive consideration of dynamic reactive power compensation equipment double feed wind generating unit to coordinate and control reactive output on the basis of both dynamic compensation and physical distribution feature of the reactive power equipment in the wind farm of Hami region in Xinjiang. It is shown by the simulation result of the calculation analysis that the proposed rea-ctive power control strategy can,in the time of meeting transient voltage stability of the wind farm which is connected to the network point,also make the reactive power margin of the reactive compensation equi-pment bigger and the transient voltage margin at the terminal of each fan more balanced.
