Condition assessment methods of substation equipment based on scoring guidelines

which are adopted by most power grid companies

lacks of feedback loop for weight correction. As a result

the weight of assessment is relatively fixed

and could not form a scientific and rational correction scheme. In this paper

the authors introduce a condition assessment weight correction model for substation equipment based on the multiple linear regression model. By testing the theory and application examples

it shows that the weight correction model which combines objective historical overhaul

maintenance

data of condition assessment and assessment validation is a more effective weight correction method

and it can provide reference for more accurate condition assessment of substation equipment.
