Abstract

Adopting series capacitors (SC) on 1000kV UHV AC transmission line can further uprate its transmission capacity, and it can also make impact on operation voltage characteristics of UHV system. Especially for heavy-load mode, as the large voltage step-up caused by SC, the issues on system operation voltage control may be more prominent. The layout manner for SC on lines and the relative fixed position between high voltage shunt reactors (SR) and SC can make great difference. Based on the planned Huainan-Wannan-Zhebei-Huxi 1000kV UHV AC double circuits transmission project, this paper researched the steady-state voltage distribution characteristics of Huainan-Wannan lines which are fixed with 40% series capacitors. Two kinds of simulation tools such as PSD-BPA and EMTPE are adopted in this study. The suggestions on the layout manner for SC and the relative layout manner between SR and SC are put forward, which can supply technique basis for the project implementation.
