Study On The Application Of The Condition Monitoring Technology In The Intelligent Substation

Intelligent substation is an important part of the smart grid. And it's the basis and premise to achieve smart grid. The condition monitoring system is one of the decisive factors of smart grid development.The condition-based maintenance is realized by the condition monitoring system of the substation, and it brings the direct and indirect economic benefits to the power system. The system can get a variety of real-time characteristic parameters of substation equipment. Combined with the expert diagnostic system, the condition monitoring system can monitor the health of the equipment in the intelligent substation. It also can find the potential failure of the equipment as soon as possible to ensure the reliable operation of the equipment. With the development of intelligent substation, condition monitoring technology has been widely used in the power system.The paper examines the structure and composition of the Smart Substation and its condition monitoring system. The main condition monitoring technology of substation is introduced in detail, and its advantages and disadvantages are analyzed. The paper takes the condition monitoring system of the Luding Substation as an example to study the practical application of the condition monitoring technology in intelligent substation. And it introduces the condition monitoring system structure and system configuration of the Luding Substation. In the last chapter, the paper proposed the problems that need to be solved urgently, and the future research directions are put forward.
