Novel Small-scaled Wind Generation System with Corresponding Control Strategy
摘要
Abstract
A small-scaled grid-tie wind generation system(SGWGS)was proposed and analyzed. Novel circuit topologies were employed,and based on the traditional SGWGS,an additional branch for energy storage was introduced into. As a result,weak wind energy could be collected,and the utilization rate of wind power was promoted. The system also adopted a novel control strategy based on the state-of-charge(SOC)of the battery. This control strategy could be divided into several modes according to different working conditions of different SOC and had the ability to adjust operating mode for the system to adapt to variable wind speed efficiently. Thus the system was able to harvest the prolonged lifetime for the battery and high flexibility towards small-scaled wind farm. At last, experiments were conducted to verify the availability of the proposed SGWGS with its control strategy and the reliability of the theoretical analysis.关键词
