| Abstract: |
| The best circuit configuration of dynamic reactive power compensation for AC induction motors is proposed，which consists of a small-size 12-pulse STATCOM and the cascaded parallel capacitor banks. By computer simulation，the capacity calculation and selection of switched capacitor and STATCOM is studied and the main circuit configuration and working principle of dual-STATCOM are discussed. The control strategy of 12-pulse STATCOM is researched. Simulative results show that the proposed compensation system may continuously adjust in large range the dynamic reactive power of AC induction motors，resulting in obvious energy-saving effect. It has better dynamic response and less harmonics than the large-size 12-pulse STATCOM working alone. |
