Abstract
This paper proposes an optimal design for control and overspeed protection in Gas turbine by means of reliability redundancy optimization. In general form, the problem is consisting of four control valves (stop valves), as a subsystem, each of them has the same components with reliability, weight and other parameters. The problem objective is to find a maximum reliability for total system in order to stop control valves in turbine’s overspeed state. The objective function is optimized and solved using a new type of Harmony Search Algorithm (HSA) that authors call it Elitism Box-Muller Harmony Search Algorithm (EBMHSA). The simulation results show that this method gives a better and accurate solution compared with the other algorithms.
