摘要
以油浸式电力变压器为研究对象,提出基于物元-时域分析的电力变压器状态评估方法,构造各评估指标的关联函数,函数值在正常运行量值范围内为正,在由量变发展到质变时函数值取负,并且根据评估值在时域上累计描绘出变压器状态评估时域曲线,且可以根据一定要求剔除因监测系统问题出现的离散数据,使得收集的评估数据更准确。
In a study involving oil - immersed power transformer, this paper proposed a power transformer condition assessment method based on matter-element time domain analysis, structured correlation functions between various assessment indicators. The function val- ue was positive when operating normally. While quantitative change going to qualitative change, the function value was negative. Based on assessed value, the time domain curve of power transformer condition assessment could be traced out. According to a certain re- quirement, the discrete data could be removed due to monitoring system failure, which made the monitoring system more accurate.
