Abstract

Abstract: 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 Chengdu and Chongqing grids by 2020.

Key words: SVC, UHVAC, UHVDC, Power System
