摘要

現代化的電子廠房或商用辦公大樓在設備運轉自動化及節約能源之趨勢，使用許多非線性負載設備做微調控制，而佔整體耗電量最大的空調系統、製程系統，運用電力電子產品更甚為由，又以變頻調速驅動器占最大宗，其造成電力品質汙染及功率因數降低的比例日益嚴重，故減少電力品質汙染及提高運轉功率因數為其重要。
本論文以內嵌式現場可程式邏輯閘陣列(FPGA) 之可程式自動化控制器(PAC)設計方式，開發一套適用於測量非線性負載設備諧波污染之電力品質監測設備，以AHU(Air Handling Unit)變頻傳動設備作為實驗對象，將PAC電力品質監測設備之測試數據進行驗證並與集合式電錶(PM710)與進行比對。
配置兩種諧波抑制設備(交流電抗器、主動式電源回生設備)進行電力諧波改善測試，以電力品質監測設備測量AHU變頻器搭配諧波抑制器後，電力品質改善之比較，分析各諧波抑制器之效能。並評估使用主動式電源回生設備(Active Frond End)應用在AHU變頻傳動設備中，測試該設備做為諧波抑制器並進行制動回生能源回饋電網實行的可行性。

The present paper uses FPGA and the PAC design way, develops a set of electric power quality monitor equipment, this equipment is suitable for the survey non-linear load equipment overtone pollution. The test equipment is AHU (Air Handling Unit) the frequency conversion transmission equipment. PAC power quality analysis system for the test data to verify. Finally carries on this experimental result and the Multi power monitor (PM710) gauging result the comparison.
This paper uses two kind of harmonic suppression equipment (include AC reactor, active renewable power supply) to carry on the electric power overtone improvement test. Power quality monitoring equipment to measure the AHU drive, and then with harmonic suppressors, the comparison for power quality improvement, and analysis of the performance of harmonic suppressors. Then assessed the use of active renewable power equipment, and four-quadrant operation of AC motor characteristics of renewable power, renewable power to the test equipment as active harmonic suppression equipment, but also for renewable energy feedback braking power is feasible to implement.
