Failure Mode and Effect Analysis of Power Transformer Based on Cloud Model of Weight
Abstract: As the key component
of a power system, the power transformer directly impacts the reliability and
safety of the system. Failure mode and effects analysis (FMEA) is a methodology
used to analyze potential failure modes within a system and has been used
extensively to examine the power transformer’s performance in various potential
failure scenarios. However, the FMEA method has several flaws; for example, the
non-differential analysis of evaluation index and the impossibility of evaluating
the actual risk among risk priority number (RPN) values that on the surface are
equal. The cloud model of weight incorporates the relative importance of index.
This paper proposes applying FMEA based on the cloud model of weight to assess
a power transformer for risk, and shows that this method can effectively
overcome the defects of traditional FMEA assessment methods.
