Research on Prediction Method for Conditions of Power Transformer Based on Grey Theory

Power transformer is a type of important electrical equipment in electrical power system,whose operating status influences the operation of the entire electrical power system directly.Hence,it is very important to predict the condition of power transformer for obtaining the overall operating status of power transformer and pointing out the risk in future.The condition prediction of power transformer is an important part in the process of condition-based maintenance.In this paper,several grey models and method to optimize grey model are introduced,and an optimization grey model based on grey forecast algorithm is established,by which a prediction for power transformer condition is realized.Based on the analysis result of practical examples,it is revealed that the grey forecast algorithm has high precision,which is more suitable for prediction of power transformer conditions.
