Abstract

The main substation equipment serves as the core hub of the power grid, and its reliability directly affects the safety of the power grid. The traditional periodic maintenance mode is likely to lead to “over-maintenance” or “under-maintenance”, intensifying the pressure on equipment operation and maintenance. Aiming at the current situation of grid equipment maintenance, this paper proposes a differentiated maintenance strategy based on fault consequences. Firstly, it analyzes the existing problems in the current maintenance system, such as insufficient monitoring data, low data integration, limitations of the expert system, and the lack of reliability assessment standards. Then, it puts forward the implementation of differentiated maintenance through three stages: equipment fault consequence assessment, equipment status evaluation, and maintenance strategy formulation. Specifically, it includes constructing an equipment fault mode analysis model, determining the control level by combining health assessment and importance assessment, and formulating differentiated strategies covering condition monitoring, periodic maintenance, and corrective maintenance based on the principle of logic decision-making. This strategy effectively solves the problems of resource waste and reliability risks in the traditional maintenance mode by optimizing the maintenance cycle and project combination, and improves the lean management level of equipment. The application prospects show that this strategy can not only reduce operation and maintenance costs and improve equipment reliability, but also promote the management innovation of power grid enterprises and provide decision-making support for the construction of a modern equipment management system. The research results have important practical value for ensuring the safe and stable operation of the power grid and improving the economic benefits of enterprises.
