Abstract


This paper evaluates the risk of transmission equipment fault combined with the safety of transmission equipment based on condition monitoring. First of all, the monitoring system monitors important parameters related to the environment, electricity, and machinery in the operation of the power transmission equipment to determine the operating status of the power transmission equipment. Secondly, the impact of transmission equipment on power system risks is reflected by risk indicator. The proposed risk indicator combines the probability of transmission equipment failure and the importance of the equipment. Finally, a reliable and safe maintenance method is determined while taking into account the operating status (reliability) of the transmission equipment and the impact (importance) of the equipment on the system. This method can more reasonably allocate maintenance resources and improve the reliability and safety of power system operation
