Substation equipment, state detection, design
Substation equipment plays an important role in the power system, and its running state is directly related to the quality of work and life of power users. However, at present, the degree of automation of substation equipment status monitoring is not obvious, many areas still stay in the traditional operation and maintenance mode, this traditional monitoring mode has many adverse risks, easy to pose a threat to the life safety of operators, and even difficult to find substation equipment problems, unable to ensure the stable operation of the power system. At the same time, the system architecture, software structure, and database technology of the condition monitoring system are not mature, and there are still greater challenges. Based on this, the key technologies of the condition monitoring system of substation equipment are studied, such as software and hardware design, database design, etc., and at last, the test research is carried out to better break through the above limitations. The results show that the condition monitoring system of substation equipment designed in this paper has strong feasibility, each module function can run reasonably, and the response time can be kept at about 3 s. The purpose of this study is to improve the intelligent level of condition monitoring of substation equipment and promote the development of substation business.
