中文摘要 | 近年來隨著電力網路日漸龐大,用電設備日趨複雜電力品質已漸受國人的關心。由於非線性負載所造成諧波污染是改善電力品質中刻不容緩的重要議題。基於上述的原因,本文擬以主動式電力濾波器,消除負載所造成的諧波污染,更進一步提高系統功率因數,完成電力品質維護工作。文中提出新的方法來計算主動式電力濾波器補償參考電流信號。並針對不同的變流器電流控制技術(1)三相獨立磁滯電流控制(2)三相獨立三角載波電流控制(3)二相相依d-q軸空間向量控制,分別觀察在各種情況下主動式電力濾波器的性能。利用模擬軟體SIMNON模擬主動式電力濾波器工作情形。 |
英文摘要 | Power electronics have been widely used in ac to dc converters. They own performances of fast response, small volume, and high efficiency, but serious power pollution is also introduced. Traditional solutions are using capacitor and inductor to make up passive filter for solving harmonics problem. To improve system power factor, a reactive power compensator is used to increase the power efficiency and reduce the transmission line loss. Active power filter not only has the properties of reactive power compensator but. also simultaneously eliminate harmonic currents. This paper presented new method of study of the algorithm compensated-reference-current-computing and the current control techniques of shunt active power filter. For generating compensated currents three kinds of current control are used. Including 1) three-phase independent hysteresis band control 2) three-phase independent triangular carrier control 3) two-phase dependent d-q axis space vector control. This paper studies the performance of steady state, dynamic response, and current harmonic spectrum distribution. The control algorithms are simulated using software SIMNON. |
