Abstract In order to study the self-excited vibration of ball valve in pumped storage power station and maintain the normal operation of equipment, a modeling and analysis framework for self-excited vibration of ball valve is proposed. Firstly, the comprehensive simulation model of self-excited vibration system is established based on the method of characteristics through the propagation characteristics of water hammer wave in pressure pipe and the leakage characteristics of flexible valve; Secondly, the uncertain model parameters are optimized based on particle swarm optimization (PSO) algorithm to improve the consistency of monitoring data and simulation results; Finally, four comparative schemes were designed based on the optimization model to analyze the self-excited vibration characteristics. The results show that the larger the initial disturbance, the faster the growth rate of self-excited vibration; when the water hammer wave velocity in different pipelines is consistent, different pipeline length combinations will have a significant impact on self-excited vibration; the length and diameter of the bifurcated pipeline affect the frequency and growth rate of self-excited vibration respectively; the double flexible valve system will further increase the growth rate of self-excited vibration.

Key words： ball valve self-excited vibration method of characteristics particle swarm optimization parameter optimization
