碩士 === 國立中山大學 === 電機電力工程國際碩士學程 === 101 === The harmonic impact caused by wind turbines should be carefully investigated before wind turbines are interconnected. However, the harmonic currents of wind turbines are not easily predicted due to the variations in wind speed. If the harmonic current outputs can be predicted accurately, the harmonic impact of wind turbines and wind farms for distribution systems can be analyzed efficiently. Therefore, this thesis analyzes the harmonic current characteristics of wind turbines and investigates the feasibility of developing harmonic current predictors. Field measurement, data sorting, and analysis are conducted for the wind turbines. Based on the proposed harmonic current predictor, the stochastic harmonic impact analysis for distribution systems with wind turbines is investigated. OpenDSS is used for harmonic impact analysis. Test results demonstrate the validity of the proposed harmonic current predictor and stochastic harmonic impact analysis.
