摘要
特高压南阳变的建成将使河南电网成为联结华北、华中、西北电网的重要枢纽,研究新的联网形式下特高压及河南电网的运行特性,是确保华北-华中电网安全稳定运行的必然要求。本文深入研究了特高压南阳变建成后特高压联络线及鄂豫断面的输电能力、华北-华中电网安全稳定水平、特高压及河南电网电压无功特性,结果表明特高压南阳变建成后电网输电能力、安全稳定水平、电压无功调节能力均有明显提高,宜结合电网规划,加快特高压南阳变建设进度。
After Nanyang Ultra-high Voltage （UHV） substation is completed, Henan power grid will be the important junction connecting with North China, Central China and Northwest Grids. In order to ensure the security and stability of North China and Central China power grids, it＇s impending to study the operating characteristics of UHV and Henan Grid under the new networking structure. This paper studied the transfer capability of UHV tie line and Henan-Hubei transmission section, the security and stability of North China and Central China power grids and the reactive power-voltage characteristics of UHV and Henan grid in detail. The research results show that the power grid has the remarkable improvment in transfer capability, the levels of security and stability, and reactive power-voltage adjusting ability after Nanyang substation is completed. So expediting construction schedule of Nanyang substation is reasonable.
