摘要
通过对无功补偿原理和方式的研究,设计了一种基于DSP2812和高精度电能计量芯片ATT7022A的低压动态无功补偿控制器。提出了一种新型的电容器组投切策略,使得电容器组能准确的投切到位,减少了电容器组在临界区域的频繁投切,提高了无功补偿的精度和效率。充分考虑了对电力电容器组的保护,减小了电容器组的损耗,保证电容器组长期安全稳定运行。
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.
