本論文旨在研究小型風力機組與低壓住宅配電系統併聯規範部分條文之適切性。首先應用商用套裝軟體MATLAB/Simulink建構永磁式小型風力機與台灣地區典型低壓住宅配電系統之等效電路模型;其次,模擬、分析在各種併聯運轉情況下,小型風力機對低壓住宅配電系統電壓、電流、頻率與諧波之衝擊情形;最後,依據衝擊分析所得結果,並參考國外相關併網規範,深入探討我國現行小型風力機在低壓配電系統併網有關併網容量、運轉功因、不平衡運轉、併網保護與諧波管制等規範之適切性,期提出修訂規範之具體建議。小型風力機併網規範之訂定是否適切,對電力公司及裝機民眾均甚重要。本論文研究成果有助於小型風力機併網衝擊之掌握、併聯辦法之修訂以及小型風力機之適切裝設。
The major object of this thesis is to investigate the appropriateness of interconnection codes for connecting small wind turbines (SWTs) to low-voltage residential distribution systems. First of all, the equivalent circuit models of SWT and a typical low-voltage residential distribution system in Taiwan are built using commercial software packages, MATLAB® and Simulink®. Next, based on these equivalent-circuit models, the effects of operation of SWTs on the system voltages, currents, frequency and harmonics of the low-voltage distribution system are then simulated and analyzed under various interconnection conditions. Final, in view of the simulation results and with reference to international SWT interconnection rules, the appropriateness of requirements of SWT interconnection rules in Taiwan on the interconnection capacity, power factor, unbalanced operation, interconnection protection and harmonics were examined, and then some advices are proposed. To legislate for SWT interconnection is very important for electric power companies and their customers considering installing SWTs. The research results are of value to realize the impact of small wind turbines on a low-voltage distribution network; to establish right and proper grid-interconnection codes, and to correctly install small wind turbines.
