架空地线临界融冰电流估算方法研究
摘要
Abstract
Overhead line ice is one of the more serious disasters affecting the normal operation of the power grid,especially the earth wire is more prone to ice,it is necessary to calculate the overhead earth wire DC melting current,and the existing empirical formulas as well as the application of the more Bursdorff melting current formula is more complex,and some of the parameters are difficult to measure.Therefore,this paper presents a method for quickly estimating the critical ice melting current of known overhead earth wire under the conditions of different wind speed,ambient temperature and icing thickness.The simulation model is built by finite element software,the data set is calculated,and then the function expression of related variables is obtained by multiple linear regression fitting,and compared with the calculated value.关键词
