中文摘要: 提出了一种梯度电容调控的无功功率补偿控制器设计方法。采用不等容分组方法,提高投切电容的容量精确性,降低调控时间。利用ATmega2560芯片,实现对系统功率因数和电流电压的测量、投切电容的控制等功能。设计了系统的硬件电路,并通过软件进行模拟仿真。仿真结果表明,在负荷变化和有谐波影响的情况下,采用梯度电容调控的无功功率补偿控制器可以迅速将功率因数补偿至0.98以上。
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.
