中文摘要 | 本文探討某化工廠被動式諧波濾波器之最佳化設計。應用最佳化-強健可行方向法,以電流總諧波失真為目標函數,同時考慮各次電流諧波失真、虛功率補償與調諧點為限制條件。研究結果顯示,除可避免傳統嘗試法耗時缺點外,並能使並聯共振點避開諧波頻率,降低系統諧波失真,以提升電力的品質。化工廠原先所裝設濾波器雖可解決諧波電流放大問題,但是在濾波與補償功因上的能力不足,因此以最佳化方法重新設計濾波器,使系統不但無並聯共振的諧波放大現象,諧波污染也降至最低。 |
英文摘要 | This paper presents the passive filter design in a plastic plant using a robust feasible directions method. We consider the total harmonic current distortion as the objective function and constraints function, including harmonic distortion, reactive power compensation, and resonant points. The results reveal that the method is less time-consuming than the trial-and error approach. In addition, the present method can reduce the harmonic distortion, prevent resonant points close to harmonic orders, and improved the power quality. The original filters in the plant can eliminate the harmonic amplification, but cannot provide enough reactive power. The present method not only solves the amplification problems, but also greatly reduces harmonic distortion. |
