| Abstract | One of the principal issue of energy conversion from wind energy to electrical energy is the optimization of its conversion process. Energy conversion is called optimum if the power lost is ÃÂÃÂ minimum. The condition can be attained at the development stage of a wind turbine prototype. ÃÂÃÂ This research will determine the optimum value theÃÂÃÂ variables of ÃÂÃÂ various operation condition by using ÃÂÃÂ multivariables Conjugate Gradient (CG) optimization algorithm. It is found that the optimum value is attained atÃÂÃÂ H = 1,0 m and D = 0,6 m, hence minimum power lost. The performance of turbine prototype design at laboratory, showed that the turbine can testing at low and high wind speed and ÃÂÃÂ ÃÂÃÂ the irrespective of wind direction condition.
