由於半導體功率元件的發展及電力電子技術的進步,以二極體、閘流體等元件組合成的前端整流電路,均被廣泛地使用於各式工業負載與民生電器用品,如可調速馬達驅動器(adjustable speed drive, ASD)、切換式電源供應器(switch-mode power supplies, SMPS)、脈波寬度調變轉換器、電腦相關產品、日光燈安定器、傳真機、影印機、等。此種前端的整流電路具有非線性的特性,導致其電流含有大量的諧波,在電力系統中造成諧波電壓及諧波電流的污染。隨著電力電子設備的應用大幅成長,電力諧波抑制遂成為一重要課題。
非線性負載增加使得電力系統的電壓失真日益嚴重,因此,本論文提出以並聯式主動濾波器(shunt active filter, SAF)來抑制放射型配電系統的諧波電壓,與傳統主動濾波器安裝於個別用戶負載端,來改善非線性負載的諧波電流使電源電流趨近弦波的用意不同。
本論文將包括緒論、文獻回顧、並聯式主動濾波器之操作原理、模擬結果與分析、實驗結果與分析及結論等六個章節。緒論涵蓋諧波的來源與影響、諧波的改善與補償與本研究之動機;文獻回顧簡介過去對電力系統諧波的改善機制,並綜合優劣提出應用於放射型配電系統的有效解決方法;再針對並聯式主動濾波器之操作原理、控制法則進行說明,以電腦模擬及實驗室原型測試電路加以驗證,最後探討並聯式主動濾波器於配電系統最佳放置地點。
Due to the progress of power semiconductor technologies and power electronics technologies, applications of power converters have increased significantly in recent years, such as adjustable speed drives, switching power supplies. Most of these applications require diode rectifiers or thyristor rectifiers as the AC/DC front-ends. The nonlinear nature of the front-end rectifiers draw significant harmonic current from the utility grid, which result in harmonic distortion of current and voltage in the power system.
In this thesis, a shunt active filter (SAF) is proposed to restrain harmonics propagation of a radial power distribution line. The operation principle and the control algorithm of the shunt active filter system will be presented. The functionality and performance of the proposed system will be verified by computer simulation and prototype experiments. The active filter will be installed on various points along the radial line to test its effectiveness on suppressing voltage harmonics.
