Steady Regimes of a Savonius Rotor-Based Wind Power Generator with Voltage Stabilizer

A small-scale wind power generator is studied, in which the operating element is a Savonius rotor. The electric circuit of the generator comprises a voltage stabilizer and load resistance. Based on phenomenological considerations, a mathematical model of this electro-mechanical system is constructed. As a result of analytical study of this model, it is shown that the hysteresis phenomenon occurs in this system when certain conditions are imposed on the parameters. It should be noted that this hysteresis is due to the presence of a voltage stabilizer. A series of experiments are performed. Based on the obtained experimental data, the parameters of the proposed model are identified. The results of the experiments are in close agreement with the results of the analytical study. An algorithm for regulating the load resistance is proposed aimed at reaching the maximum output power.
