输电线路线损的多参量修正算法

Multi-parameter correction algorithm for transmission line loss

随着线损精益化管理的不断推进,输电线路线损计算准确性愈加重要。目前的线损计算方法未考虑负荷水平、时钟准确度以及计量装置配合影响,导致实际统计与计算结果差别较大,不利于线损管理的精益化发展。以现有理论线损计算方法为基础,对统计线损影响量进行分析,提出多参量修正算法,提高线损计算的准确性,并以重庆—恩施500 kV超高压输电线路作为算例,证明了该方法的有效性。

With the continuous advancement of line loss lean management,the accuracy of transmission line loss calculations is becoming more and more important.The current line loss calculation method does not consider the load level,clock accuracy,and the influence of the metering device,resulting in a large difference between the actual statistics and the calculated results.It is not conducive to the lean development of line loss management.Based on the existing theoretical line loss calculation method,this paper analyzes the statistical line loss influence amount,and proposes a multi-parameter correction algorithm to improve the accuracy of line loss calculation.The effectiveness of the method is proven by taking the Chongqing-Enshi 500 kV ultra high voltage transmission line as a numerical example.
