摘要
为解决川渝负荷中心电网本身动态无功支撑不足、提高电网稳定水平且满足未来四川更多富余电力东送问题,结合未来川渝交直流电网规划,从川渝交直流特高压电网相关站点加装静止无功补偿器(SVC)的具体条件和可行性等方面,研究川渝交直流特高压电网相关站点加装SVC对提高电网稳定水平和川电外送能力的积极作用。研究结果表明:2020年川渝电网相关特高压站点上加装一定容量SVC后,整个交流通道的送电能力可提高约3 700 MW。
In order to resolve the problem of insufficient dynamic, reactive power support of the load center of Chengdu-Chongqing power grid and improve the grid dynamic stability and transfer spare hydropower from Sichuan to eastern China, the grid dynamic stability by installing SVCs in relative substations in Sichuan-Chongqing Grid of UHVAC/UHVDC was studied based on the planning of the AC-DC Sichuan-Chongqing power grid and the feasibility study of installing SVC at some relative nodes. The results show that the capacity of the AC passage can be increased by about 3 700 MW after installing SVCs with certain capacities on relative UHV notes in Chcngdu and Choogqing grids by 2020.
