| Abstract: | Heavy nonlinear power load in mine power distribution network injects harmonic power and large quantity of reactive power into the distribution network,thus the power factor of mine power distribution network obviously decreases.To solve this problem,a digital signal processor based dynamic reactive compensation control system for mechanically switched capacitor banks,in which high-voltage vacuum contactors are used as the switchers,is designed.The designed control system possesses following features: simpl... |
