Single phase power for remote area using Savonius rotor based hydropower generation

In this paper the feasibility of using Savonius rotor for hydropower generation is presented. A detailed investigation for possible generation of single phase power using the same coupled to an asynchronous generator is carried out. The complete system is modeled in MATLAB/Simulink environment, one without using any power converter and the other using an AC-DC-AC converter. The control algorithm of the system is worked out. Comparison of the performances of both the systems is presented. In order to achieve single-phase power output the three-phase 3-wire system is converted to three-phase 4-wire system using a transformer with turns-ratio of 1:1. An LCL filter is used to smoothen the ac output.
