摘要
随着内蒙古电网高比例新能源的不断接入,系统动态无功相对不足问题日渐凸显,以新增的白音华负荷项目及配套电厂为算例,在白音华电厂配置一台同步调相机,仿真分析系统暂态电压稳定水平、白音华变电站带负荷能力和短路电流影响。结果表明,增设白音华调相机对暂态电压稳定问题能够起到积极作用,故障时可及时提供无功电压支撑和一定的短路容量,提升白音华变电站带负荷能力。
With the continuous access of a high proportion of new energy in Inner Mongolia power grid,the problem of the relative lack of dynamic reactive power in the system has become increasingly prominent.Taking the newly added Baiyinhua load project and the supporting power plant as an example,a synchronous compensator is configured in Baiyinhua power plant,in order to simulate and analyze the system transient voltage stability level,load capacity and short⁃circuit current effects.The simulation results show that the addition of the Baiyinhua compensator has a positive effect on the transient voltage stability problem.It can provide reactive voltage support and a certain short⁃circuit capacity in time to improve the load capacity of Baiyinhua station.
