| Summary: | 碩士 === 國立中央大學 === 電機工程學系 === 105 === The goal of this thesis is to show the improvement of the power quality which sometimes distorted by various load with DSTATCOM (Distribution Static Synchronous Compensator). We use different control strategies to analyze load current and calculate the ideal reference current. Once we calculate the reference current, we use PWM Technique to generate compensation current which generated by three phase two-level inverter.
Instaneous Power Theory is a traditional control strategy which is uncapable of dealing with the unbalance current situation. ADALINE theorem is a ideal way to solve this problem. LMS algorithm is traditionaly used for updating weight of Adaline theorem. However we discover that there is unstable steady stae by using LMS algorithm. As a result, another algorithm presented in this thesis is applied to deal with. After doing lots of experiement we discover the algorithm presented in ths paper has better performane in both transient state and steady state.
Finally, we do all kinds of experiement to see the the performance based on aboved-mentioned three different strategies mentioned above. Beside we work hard to show the adavantage of the algorithm presented in this thesis.
