摘　　要：本文分析江西中长期能源供应形势以及电网发展趋势,提出江西未来将受入第2回直流并落点南部电网;利用直流短路比,明确南部电网加强方案;在此基础上,对江西南部电网出现的电压稳定问题进行分析,并提出应对措施,以及调相机、SVG两类动态无功补偿方案;进一步通过仿真分析和经济比较分析对上述方案进行论证与验证,提出相关建议。The medium and long term energy supply situation and power grid development trend in Jiangxi is analyzed in this paper.It is proposed that the second DC will be constructed in the southern power grid of Jiangxi in the future.The strengthening scheme of the southern power grid is clarified through improving the DC short circuit ratio.On this basis,the voltage stability problems of the power grid in southern Jiangxi are analyzed.The corresponding measures and two types of dynamic reactive power compensation schemes,namely phase modifier and SVG,are proposed.Through simulation analysis and economic comparison analysis,the above scheme is demonstrated and verified and relevant suggestions are proposed.
