In recent years, power operation accidents have become more and more frequent, This has a certain adverse impact on the safe operation of the power grid. In addition to faults caused by power equipment, There are also accidents caused by nonstandard equipment maintenance and lax production management process. The article is based on the basic theory of quality control of on-site operation system, A standardized on-site quality control system was established, and the production mode was analyzed and studied. Then, based on the quality control of the operation system, the requirements of the field operation system quality control system is analyzed, put forward the basic concept of the field quality control, and put forward the specific quality control measures and operation methods to solve the relevant problems. This design is of great practical significance to improve the economic benefit of electric power enterprises. Finally, the effectiveness and progressiveness of the on-site quality control system are demonstrated through the actual case analysis, This design has important practical significance for improving the economic benefits of electric power enterprises.
