中文摘要 | 由於許多交直流電源轉換器均在直流端並聯一直流電容以作為穩壓之用,此大電容將造成負載諧波特性的改變;此類諧波源負載,如果使用現今常見的並聯型主動式電力濾波器並不能很有效解決此類諧波問題;因此本文將採用串聯型主動式電力濾波器,並配合同時量測電源電流及負載電壓的混合式控制模式,即可有效解決此類諧波問題。而串聯型主動式電力濾波器的另一項重要功能是可以用於調整負載電壓;本文採用以同步座標轉換法為基礎之快速演算法,能快速且容易的估算出所需之補償電壓值,使得串聯式主動式電力濾波器能有效地用於改善負載端電壓之電壓驟降及電壓不平衡等問題。 |
英文摘要 | Because a bulk smoothing capacitor is usually installed on the DC side of many AC to DC converters, the characteristics of harmonic loads will be influenced by this capacitor. Nowadays, shunt active power filters can’t reduce harmonics effectively for this voltage type harmonic-producing load. Therefore, a series active power filter (SAPF) is designed to meet the requirements of voltage-sourced harmonic loads. Both source current and load voltage are detected in order to reach the compensation voltage for the SAPF. Another objective is to use series type active power filter for load voltage regulation. A novel algorithm based on synchronous axis transformation method is proposed to calculate the reference signal for the compensation voltage in a very efficient manner. The designed series type APF can be used to compensate for voltage sag and voltage unbalance very effectively. |
