Abstract: A fuzzy combined evaluation method for power transmission equipment condition is proposed. Based on combined weight theory, the proposed method adjusts weights based on the current status of different components in the transmission equipment. A systematic equipment status evaluation system is built through analysis of multiple system status information. By combining variable weight comprehensive theory, AHP method and entropy weight method, the complete weighting coefficients for all status information on the system are obtained. With full consideration of balance between evaluation factors and weighting coefficients change, the proposed fuzzy evaluation method can be used to assess overall transmission equipment operation status and predict system development trends. Finally, the validity of proposed method is verified by evaluation of a practical power transmission equipment condition.
