Abstract


This paper proposes a method for evaluating the operating status and reliability of power transmission equipment in power systems. First, by analyzing the aging factors, common faults, and major faulty components of the main transmission equipment, the main condition monitoring parameters of each transmission equipment are determined. Then, the key parameters such as the environment, machinery, and electricity of the transmission equipment are monitored to obtain the operating status data of the transmission equipment, and fault limits and alarm limits are set to determine the operating status of the transmission equipment. Finally, a health index for monitoring parameters and a comprehensive health index for transmission equipment are proposed. This method has a wider scope of application and a more specific analysis process than previous methods, which is conducive to analyzing the working status of power transmission equipment and improving the reliability and safety of normal operation of the power system
