| Summary: | 碩士 === 國立中山大學 === 電機工程學系研究所 === 107 === In this thesis, a phasor measurement system (PMS) is developed for phase measurement of transformers. The PMS has been applied for field measurement of distribution transformers to identify their phase and correct the corresponding attributes of the distribution mapping management system (DMMS) in Taipower. By retrieving the information of the line segments and transformers from the DMMS, the network modeling of distribution feeders is derived to analyze the three-phase unbalance. To demonstrate the effectiveness of the proposed rephasing strategy, three distribution feeders were considered in case studies. By comparing the phase currents and neutral current of a test feeder before and after rephasing, the three-phase balance of the distribution system can be significantly enhanced with the PMS to identify the phasing of distribution transformers for deriving the rephasing strategy of the distribution feeders.
