由於電力品質之良窳對於煉油生產製程影響甚鉅，尤其加入WTO後油品市場邁向自由化，生產成本的高低更是市場競爭的要素，本論文即提出利用電力品質監錄器完成電力系統動態特性之分析，並以實際之中油大林煉油廠用電負載來分析電力即時資料，及透過廠內網際網路輔以檔案上傳方式將動態數據資料檔傳送至電力工程人員，俾進行三相不平衡分析、諧波分析、頻降分析與電壓瞬降分析，因而可提出各種改善方案與預防策略。本文所提之方法，業經實際應用於系統運作後，確能改善電力品質、提高供電穩定性與可靠度，提升產品績效及競爭力。

In order to move toward the liberalization of petroleum market, the electric power quality has played an important role such that the refinery performance can be significantly increased. This also motivated the research of this thesis. In this thesis, the dynamic measurement of Talin Refinery of Chinese Petroleum Corporation is proposed where data are recorded and provided for the power quality analysis by engineers. Analysis results consisting of voltage unbalance, harmonic analysis, frequency drop, and voltage sag are all included for the reference of power quality improvement, where test are validated on the site. From these test results, they helpfully support the effectiveness of the proposed approach.
