| 摘 要： | 随着我国风电的快速发展,带来了大规模风电接入系统的稳定性问题。介绍风电大量脱网对系统频率的影响,并阐述风机低电压穿越问题(LVRT)。通过对WSCC-3机9节点系统的可视化仿真,展示了电网故障期间各节点电压波动情况,定性分析了并网风机低电压穿越过程。此外,算例结果表明,基于PowerWorld软件的区域电压可视化技术,有助于调度运行人员直观、形象地掌握事故状态下的全网运行情况。

| Abstract: | Fast development of large-scale wind power farms and their integration affect power grid stability.The impacts of wind turbine tripping on the grid frequency and requirement for low voltage ride through(LVRT) capability of wind turbines were discussed.The simulation of the WSCC 3-machine 9-bus system by visualization technology conveyed the grid voltage trajectories during tripping disturbance.Moreover,the qualitative analysis of LVRT was made for integrated wind turbines.Simulation results proved that visu... |
