宁夏北部电网供电瓶颈问题研究

针对宁夏北部电网未来几年存在的供电瓶颈问题,按照提高地区供电能力、优化区域网架结构的思路,通过电力系统模拟计算,提出将750 kV电压等级引入北部地区、将宁东地区电源以220 kV电压等级接入北部电网负荷中心和补强月牙湖变电站主变压器及相关送电通道3种解决方案,并对方案进行比较。结果表明:方案1将750 kV电压等级引入北部地区能够为北部电网提供可靠的电源支撑,可从根本上解决北部电网近远期电力供需矛盾问题。

Study on the problem of power supply bottle neck in Ningxia north power grid

FAiming at the problem of power supply bottle neck of Ningxia north power grid in thenext several years, based on the ideas of improving area power supply capability and optimizing thestructure of district network frame, by simulating calculation of electric power system, puts forwardthree kinds of schemes: to lead 750 kV voltage level into northern area, to interconnect Ningdong areapower sources as 220 kV voltage level into load center of northern center, and to strengthen the maintransformer of Yueyahu Substation and relevant power supply transmission channel, and compares thethree kinds of schemes. The result shows that the first scheme, to lead 750 kV voltage level into north?ern area, will provide reliable power sources support for north power grid, can solve power demand andsupply conflict in short and long term of north power grid.
