臺灣博碩士論文加值系統

本論文提出多種最佳化變壓器與饋線配接方式的法則以改善配電饋線的三相不平衡問題及提升配電系統的運轉效率。本論文利用台電的四條實際饋線來驗證所提出之配接法則的有效性。分析結果顯示採用本論文所提出之配接法則，確實可有效降低饋線三相電壓、電流及負載的不平衡率；饋線損失、壓降亦有顯著改善，同時亦可提升接地故障保護電驛的靈敏度，減少接地故障保護電驛誤動作的次數及提高供電品質。

This thesis presents many algorithms for perfecting the connections between distribution transformers and a primaryfeeder to improve the imbalance as well as the operationefficiency of a distribution feeder. Four Taipower distribution feeders were used to verify the validity of the proposed algorithms. The results indicate that three-phase voltages, currents and loads imbalances along a feeder as well as thevoltage drop, line losses and the frequence of malfunction ofgrounding relay can be effectively reduced. Consequently, the power quality of a distribution system can be improved by usingthe proposed algorithms.
