Valve Closure Optimization Using GA

Authors:

Abstract

In this paper a solution for valve closure optimization problem is presented. Nonstationary gas-liquid mixture flow in a pipeline is simulated using essentially nonoscillatory schemes for the appropriate conservation law model. The task of minimizing pressure oscillations generated by valve closure is solved using genetic algorithm. The obtained results show high accuracy and the approach is new and improved in comparison with the literature. Presented methods are applicable to any other similar pipeline optimization problem and have large application area in hydroelectric power plants, nuclear power plants, oil industry, ships, etc.
