基于最小二乘法的变压器经济运行参数校正

电力变压器由于各种原因在运行一段时间后,其实际参数与铭牌标定不再一致。本文利用现场测得的运行数据,在考虑了温度对参数影响的情况下,运用最小二乘法进行曲线拟合并计算出变压器实际参数,为变压器的经济运行提供相应技术依据。

The Verification of Transformer Economical Parameters Based on Least Square Method

Because of some reasons the actual parameters of transformer after running a time are disaccord with nameplate's parameters.This paper makes use of service data of the transformer from site investigation in order to confirming the actual transformer's parameters.In this paper the influence of temperature and reactive power to the transformer's parameters were calculated in.At the end we can figure out the actual transformer's parameters by least square method and curving fittings.It provides relevant techni...
