摘要
分析了并网运行的风电机组对电力系统电压稳定性的影响。从静态电压稳定性角度,将风电机组等效成随风速变化的有功和无功电源,分析了风电机组的控制方式、无功功率出力对电压稳定性的影响。动态稳定性的研究中,采用IEEE39节点标准测试系统,仿真结果表明:在提高电压稳定性方面,恒电压控制比恒功率控制具有明显的优越性。
The influence of wind turbine generators interconnected to grid on voltage stability of power system was researched. From the viewpoint of static voltage stability,the wind turbine was equivalent to active and reactive power determined by the wind speed. The effects of wind turbine control mode and reactive power output on the voltage stability were analyzed. For dynamic stability,IEEE 39 standard test system was used. The simulation results show that constant voltage control is much better than constant power in the aspect of improving voltage stability.
