Failure Analysis of Secondary Equipment in 110 kV Substation and Research on Its Automation System

Zhang De-kun

[Abstract]The efficient development of my country's economic system has further promoted the innovation of the power industry. At present， in order to further meet the needs of society for production and life， the construction of power systems has also become the focus of many parties. For the purpose of improving the quality of power supply， substations are also under management Mode and system optimization and innovation. The article is based on the actual case of 110 kV substation， combined with its secondary common faults and the automatic management system of daily equipment. A targeted analysis is carried out based on the specific construction content， construction plan， safety precautions， and key technical system application. It is intended to lay a theoretical and technical foundation for the daily optimization and management of the current 110 kV substation through the article.
