Two different techniques may be adopted when generating electrical energy from the wind: fixed speed or variable speed. Given the unpredictability of wind, the main advantage f adopting electronic speed variation is that energy can be generated at all wind speeds. This leads to an overall increase in the quantity of energy produced. Electronic speed controllers generate interference on the network. Various solutions are offered to eliminate this interference. An economic analysis, based on theexperience gained using a fixed-speed installation, highlights the main parameters affecting the cost per wind-generated kWh.
