近幾年來，由於高科技產業的興起，使得供電環境的要求變得比以往要來得嚴格。許多敏感性設備常因電力品質等問題的影響而無法正常操作，造成用戶抱怨。在決定電力品質改善方案之前，往往需要建立電力品質監測系統，以瞭解系統的供電品質。本論文主要目的是針對高雄地區住、工、商不同用戶類型進行供電品質之量測。記錄資料除被使用來計算諧波、電壓不平衡、電壓閃爍及電壓事故等不同電力品質之各種參數指標外，將探討電壓降對一般典型敏感性設備可能的影響程度。量測相關技術，包括監測點之選擇、記錄器之門檻設定、事故擷取能力、資料收集與分析方法等，在本論文中有詳細的說明。分析結果將與標準規範進行比較，以瞭解高雄地區實際的供電品質。

In the past years, due to the rapid growth of high-tech industries, the power supply requirements are becoming much stricter. Many of sensitive equipments are often affected by various power quality (PQ) problems to malfunction, as a result, the customer complaints. Before the mitigations of PQ are decided, the PQ monitoring system should be setup to find out the causes of PQ problems. The aim of this thesis is to establish a PQ monitoring system to investigate the quality of power in Kaohsiung Area for different types of customers. The recorded data not only are used to calculate different PQ of various parameters indices such as harmonics, voltage unbalance, voltage flicker, and voltage events, but also to confer the levels of typical devices affected by voltage sag events. The related measuring techniques include selection of monitoring sites, threshold settings of recorder, the ability to capture events, and the data collection and analysis are included in this thesis. Analysis results are compared to PQ standards to understand the actual quality of power delivery in the Kaohsiung Area.
