基于模拟退火算法的水轮机导叶分段关闭规律优化
Optimizing closure law of wicket gates in hydraulic turbine based on simulated annealing
摘要
Abstract
A new optimization model was set up to solve the contradictions between water hammer pressure and turbine speed during the transient process in hydropower stations.The model can be applied to the multi-condition optimization and the parameters can be adjusted easily.Based on the characteristic method,simulated annealing algorithm was applied to the optimization of the wicket gate closure law.In a practical case,two controlling conditions were selected in maximum volute pressure and maximum turbine speed numerical calculation,and results of different closure laws were compared and analyzed.Then the two-segment closure law was optimized using simulated annealing algorithm.The maximum volute pressure,maximum turbine speed and minimum draft tube pressure met the design requirements and the safety margins were allocated reasonably.The results show that simulated annealing algorithm can quickly and stably optimize the wicket gate closure law,which provides a new method for closure law selection in similar hydropower stations.关键词
