线路负荷融冰方案研究

Study on Overload Ice-melting Scheme of Transmission Line in Guilin Grid

针对广西桂林地区级电网实际情况,对负荷融冰技术进行了研究和可行性分析,给出了负荷融冰方案制定的思路和流程,以某条220 kV联络线为例制定负荷融冰方案,并进行潮流计算和稳定计算的校核,研究了融冰方案中考虑的各种因素,为其他地区级电网制定负荷融冰方案提供借鉴。

Based on the actual conditions of Guilin Grid, the article studies the principle and feasibility of overload ice- melting scheme of transmission line, and presents the process of preparing such scheme. A detailed overload ice - melting scheme is worked out for a 220kV transmission line, and analysis on power flow and stability is made. Various influencing factors that shall be considered are studied, and corresponding suggestions are given. The study can also be a reference for preparation of overload ice - melting scheme in other regional grids.
