Study of small-capacity wind power generation system with using Doubly-Fed induction machine.

Abstract

　Wind power has a relatively low power generation cost than other power generation methods, attracting attention from such as it is high business profitability, and introduction has been expanding.

　In this research, we aim to investigate the effect of secondary side excitation for DFIG and conduct research with the following contents. Study on power generation by secondary side drive method of DFIG. We clarify the principle of the secondary side drive method of the DFIG, simulate the wind turbine in the simulation, and examine the power generation characteristics and the efficiency according to the wind speed.
