Reliability Analysis of Instrument Power System Based on Monte Carlo-Dynamic Fault Tree

The reliability analysis of nuclear power conventional island instrument power supply system is an important part of the reliability research of nuclear power unit. Aiming at the structural characteristics of nuclear power meter power supply system, the reliability analysis method of instrument power supply system based on Monte Carlo-dynamic fault tree is proposed. According to the component composition and connection logic of the instrument power supply system, the dynamic fault tree model is established and Monte Carlo simulation is used to calculate the probability importance index of each component of the system, and suggestions for improving the reliability of the system are proposed. The simulation results show that the method can effectively and accurately quantitatively analyze the reliability of the instrument power supply system, and has the characteristics of strong applicability and high calculation efficiency. It has important guiding significance for the design and transformation of other instrument power supply systems.
