| Abstract: | A new approach for optimizing the parameters of hydro turbine governor using genetic algorithm is developed. The searching efficiency can be ameliorated by the alterable intercross probability and mutation probability. In addition, an objective function with different weight in different area is introduced, by which the undershooting of the system can be reduced. The simulation result shows that by means of this algorithm the searching efficiency is greatly improved. |
