摘　　要：随着用电负荷的增加,输变电线路利用率成为近年来关注的重点。由于导线电流限额影响因素较多,难以某一种方法提高输变电线路利用率。采用静态多点校核方法提供随环境条件变化的多个导线输送能力,简化环境因素造成的应变量,提高线路输送能力动态调整的精细度,将其与动态增容方法结合,全面提高电网运行可靠性和灵活性。With the inc, rease of power load, the utilization rate of the power trans-mission line has become a focus in recent years. Since there are many factors affecting the current limit of the conductor, it is difficult to use a certain way to improve the utilization of transmission lines. The static multi- point checking method is used to provide the transmission capacity of conductors with change of environment and simplify the dependent variable caused by the environment factor and improve the fineness of the dynamic adjustment of the trans- mission line capacity. The method combined with the dynamic capacity expansion method can comprehensively improve relia- bility and flexibility of the power grid operation. The method is applied in Suzhou Guling Substation and makes a full play of the transmission capacity.
