| Abstract: | A design method of the gradient capacitor-regulated reactive power compensation controller is proposed to reduce the adjusting time of reactive power by providing the switched capacitors with the suitable capacity based on unequal capacitance grouping method.The ATmega2560 microprogrammed control unit is used to measure the power factor,current,voltage,and to control the switched capacitor.The corresponding circuit is also designed and simulated to explore the electric properties.The results show that the reactive power compensation controller with gradient capacitor regulation can quickly compensate the power factor to above 0.98 under the load change and harmonic condition. |
