Abstract:This article aims at the contradiction between the booming of smart grid technology and the unsatisfactory management of the power equipment. The purpose is to find a way to quickly realize the safe and efficient operation of the power equipment.The theory and object used in this paper have been widely recognized in the industry, including the management and maintenance strategy of power equipment, the technology method of power equipment detection in the age of smart grid, the development status and trend of big data and visualization technology and so on, and thus has a solid theoretical and practical basis. Through qualitative and quantitative research, empirical comparison and descriptive research, interdisciplinary and exploratory research, the conclusion is that with the rapid development of information technology and the coming of the era of big data, the obstacles that power equipment management has been unable to achieve breakthrough have been broken. Then, it is proposed that only key indexes should be set up in combination with the characteristics of big data in the power industry, and the internal data logic system and external visualization system can be built at the core to realize the iteration of the power equipment management. In the end, the paper looks forward to the power equipment management in the new era, and takes the financial analysis index system as an example to make a frame construction of the power equipment management intelligent system.
