OUTPUT POWER VARIATION OF A 5-KW CLASS SMALL WIND TURBINE

Abstract

Output power of a wind turbine system is recognized to fluctuate more than that of a photovoltaic (PV) power generation system in general, and there is a concern that small wind turbines (SWTs) may cause severe voltage variation and flicker in low voltage distribution lines. In this paper, characteristics of output power fluctuation of a 5-kW class SWT system are analyzed, and compared with a same class PV power generation system. The result indicates that the high output power variation occurs much more in the SWT system.
