摘要
阐述了灰靶理论的标准模式、统一靶牌、灰靶变换、灰靶贡献度及权重确定、靶心度计算和设备状态模式分级,通过灰靶理论对变压器健康状态进行评估,用计算靶心接近度来确定变压器状态,同时利用灰贡献度解决了变压器状态评估中各指标的权重问题。
This paper expounds standards mode of grey target theory,unified target frame,grey target transition,determination of grey target contribution rate and weighting,calculation of approaching degree and classification of equipment condition.It also evaluates transformer＇s health condition,confirms transformer＇s condition by calculating approaching degree and solves index weighting problem by using grey target contribution rate.
