摘要(Abstract):
探讨了基于灰色关联度理论的变压器灰色故障诊断问题,提出了改进的变压器灰色故障诊断的方法-面积关联度法。该方法立意新,计算简便,能反映序列曲线的变化走向相似度,能全面描述序列间联系的紧密程度。仿真结果表明该方法在变压器故障诊断中的可行性,对变压器的状态能做出准确判断。
This paper proposes the improved grey diagnosis method-area relation degree method for transformer based on grey relation degree theory.The method reflects the similar degree of changing trend of sequence curves. The simulation results show that the method is feasible in transformer fault diagnosis, and can make a accurate judgement to the state of transformer.
