However, the mechanism of sec‐ ondary equipment fault is complex, which may have recessive fault, and the index required is more complex. This paper proposes a new method for smart substation secondary equipment condition assessment based on Cloud Model, establishes evaluation flow process, divides the con‐ dition level, and uses the analytic hierarchy process and varied weight process. The results show that this method can evaluate the smart substation secondary equipment condition more accu‐ rately, and provide theoretical basis for the maintenance of it.
