Research And Application Of Condition Monitoring Technology For Intelligent Substation

In recent years,the global economic situation and energy development pattern has changed,China’s economy has also made rapid development,making green energy,sustainable development,low-carbon environmental protection economy has become the focus of attention around the world.Intelligent substation as an important part of smart grid,including intelligent substation state maintenance technology is the core of intelligent substation technology.First,the paper summarizes the situation of intelligent substation and state maintenance technology,compares and analyzes the state maintenance and traditional maintenance mode.Then,it studies the on-line monitoring technology of state maintenance of intelligent substation,and introduces the intelligent substation configuration through engineering examples.Aiming at the problems existing in the practical application of state monitoring of intelligent substation equipment,the corresponding countermeasures are put forward.In this paper,the advantages and disadvantages of various schemes of existing intelligent substation equipment are summarized.Finally,it summarizes the problems in the case of intelligent substation engineering,and puts forward the possible improvement direction of intelligent substation equipment.
