In this paper we proposed multi-stage algorithm of small wind turbine power plant control when it supports maximum extracted power independently on traditional tip speed ratio using the wind speed. We made measurements of wind turbine parameters on urban and prairie territories, showed the necessity of power controlling the turbine, and vindicated the efficiency of control of small wind turbines in urban regions. We also formulated the conditions and structure of microprocessor operation, described the algorithm of wind turbine power control showing the possible situations and states. Each state is described with the corresponding microcontroller response and activity. We showed the advantages of pulse width modulation (PWM) is converting the electric values.
