    摘  要:提出一種基于層次分析法的變壓器風(fēng)險評估新方法,結(jié)合設(shè)備狀態(tài)、設(shè)備重要度、負(fù)荷系數(shù)及運行環(huán)境因素,建立了一套綜合描述變壓器安全運行的風(fēng)險評估指標(biāo)量化體系。利用層次分析法進(jìn)行設(shè)備風(fēng)險決策級融合,得出變壓器風(fēng)險指標(biāo),利用風(fēng)險指標(biāo)的大小進(jìn)行設(shè)備風(fēng)險的排序,來合理安排設(shè)備檢修,提高狀態(tài)檢修效率。以某地區(qū)兩臺500 kV電力變壓器為例對所提模型進(jìn)行驗證,風(fēng)險評估結(jié)果和實際相符,證明了該方法的可行性。

    Abstract: The paper proposed a new kind of assessment approach based on analytic hierarchy process (AHP). A set of assessment index quantification system was established considering this device status, device importance, load factor and operating environmental factors. The AHP was used to evaluate equipment risk decision fusion to obtain transformer risk indicator. According to the risk indicator, the equipment risk was sorted to arrange equipment overhaul reasonably to raise the efficiency of condition based maintenance. Taking two 500 kV power transformers in certain area for example, this paper verifies the proposed model. The risk assessment result is conformed to practical conditions, which proves the feasibility of this method.
    Key words: transformer; analytic hierarchy process; condition assessment; risk assessment
