The Power Coefficient Optimization of H-type Turbine for Wind or Tidal Current Energy Conversion Based on Genetic Algorithm
Based on the genetic algorithm theory,an optimization method and its mathematical model of the H-type tidal or wind turbine for energy conversion have been investigated.In order to enhance the turbine power coefficient,the maximum efficiency is taken as the objective function,and stream-tube model with dynamical stall effect has been reviewed as a method to calculate the fitness value of each individual.With the prototype of the vertical-axis cycloidal turbine,such optimal results as the turbine power coefficient and the relation between attack angle and blade motion are given particular analysis to sum up the reason of the improved performance of the turbine.The proposed method has been used to design a real tidal turbine. Under the choice of the optimal design variables,the results show that such method successfully reveals the optimal variables and parameters for maximum power coefficient.
