Study on Reliability Analysis of Distributed Control System of Nuclear Power Plant

Abstract

The reliability of the nuclear power plant DCS is analyzed using Markov process to establish a mathematical model. And the initial use of the model on the three indicators of reliability parameters of nuclear power plants is calculated. The results showed that the model is correct,reliable and error rate is 9×10-10.DCS applies to preliminary analysis of the reliability of nuclear power DCS. Nuclear power plant DCS reliability is high enough, the minimum time of continuous operation is up to 66667 h, compared to conventional control methods more safe and reliable.
