| Abstract: | With studying on the theory and mode of reactive power compensation, a dynamic reactive power compensation controller based on DSP and AT17022A was designed and a new control strategy for capacitor bank switching was presented, the capacitors could be controlled accurately and the frequent switching in the critical region was reduced, therefore the precision and the efficiency of the compensation were improved. The protection for power capacitor was considerated, the loss of the capacitor was reduced, the capacitors could be operated safely and stably. |
