| 摘 要： | 针对边界条件取值过于保守导致架空输电线路载流量过小而无法充分发挥输电线路的载流能力的问题,本文提出了一种基于K-Means算法的架空输电线路载流量计算方法.首先对历史气象数据进行统计分析,然后根据每月气象数据的相似性,使用K-Means算法划分时段,并选取各时段最为合适的边界条件,最后基于选定的边界条件使用摩根公式进行仿真计算.通过这种方法,可以在保证线路运行安全的条件下挖掘输电线路的隐性输送能力.

| Abstract: | The current carrying capacity of the overhead transmission lines is lowered due to the conservative value of the boundary conditions.We propose an approach to calculate the carrying capacity based on K-Means algorithm,with purpose to fully exploit the carrying capacity of the overhead transmission lines.Meteorological data of Guangzhou in recent 10 years were summarized to analyze the variation of monthly ambient temperature and wind speed,based on which the K-Means algorithm was employed to rate the 12 months into several time periods,then appropriate boundary conditions were given for each time period.The Morgan formula was used to simulate the current carrying capacity under the new boundary conditions.Simulation results showed that the current carrying capacity can be effectively increased on the premise of ensuring safe operation of overhead transmission lines. |
