南方交直流并联电网电压调控分析

Analysis of regulating and controlling of voltages in South China AC/DC Hybrid Power Grid

南方电网是世界上少有的长距离、大容量输电、交直流并联运行的电网。影响系统电压运行的因素较多,电压调控工作也是电网运行中的一个难题。通过对南方电网运行特性的分析,提出系统电压调控的主要措施,解决电压调控的难点,并提出相应的建议。

China Southern Power Grid is the first long-distance and huge capacity power grid with AC and DC power networks in parallel in China. There are many factors that affects on the voltages of the AC/DC hybrid power grid, and regulating and controlling of voltages is a difficult problem of the system operation. The paper analyzes the characteristic of the system operation in China Southern Power Grid. The main measures for regulating and controlling of voltages are brought forward. Its difficulties to be settled are analyzed, and some relevant suggestions are proposed.
