Modeling of Power Supply System And Determination of Component Reliability Parameters Based on Analysis

The reliability index of power supply and distribution system is a key index that affects the design and operation performance of the system structure. The reliability calculation and analysis can provide a powerful guide for building a more reliable structure of power supply and distribution system. In this paper, a mathematical model of power supply and distribution system structure is established by using Boolean algebra, and the influence curve of each component on the final reliability index of the system in a certain reliability interval is analyzed, which is used to understand the macro trend of the global index change. The reliability index of different system structures is compared, and the best system structure meeting the user’s requirements is determined. The reliability index requirements of each component are analyzed under the condition of reliability index requirements of users. Through the above reliability calculation and analysis, the reasonable, feasible and lowest optimal system structure and component reliability index boundary interval which meet the requirements of users are determined.
