| Abstract: | A new method of voltage control is researched and a linking drive for the utility interactive wind electricity change system(WECS) is designed. The linking drive uses the techniques of selective harmonic elimination(SHE) in pulse width modulation(PWM) inverter so that the quality of mains power can be improved,harmonic elimination achieved and right power factor obtained and another harmonic eliminator is not needed.A novel state's count way accomplished by computer is presented. |
