The technique for increasing lift force control capacitance under wind turbine power limiting conditions by plasma technology

Abstract

The need to increase the control capacitance margin under wind turbine power limiting conditions allows developing favorable conditions of operational reliability. There are two traditional methods of controlling windwheel and generator output capacity: speed control by adjusting blade angle of attack and by blade profile with airflow breakdown. Currently such means of efficient control of wind turbine as plasma drives are developed. The use of plasma technology for extending the range of controlling the wind turbine applying the technique of developing surface dc corona discharge on a blade is of appropriate interest. Taking into account this fact it is necessary to carry out the mathematical modeling which gives an idea of the controlling range value of the studied model.
