摘要
针对有源电力滤波器在应用中直流侧电容值的选择问题,详细分析了有源电力滤波器在正常工作时的能量流动,并基于能量守恒原理和瞬时功率理论建立了能量平衡方程,给出了直流侧电容值的选择方法。在直流侧电压参考值确定后,直流侧电容值由APF的补偿容量、直流电压允许波动幅值共同决定。仿真结果证明了理论分析的可行性和正确性。
In this paper,aiming at the issue of dc-side capacitance selection in active power filter,the transfer of power of active power filter is analyzed in detail.Based on the law of conservation of energy,an equation is discussed and a method of the selection of dc-side capacitance is derived.After the reference dc voltage of the dc-side giving,the dc-side capacitance can be calculated by the capacity of active power filter and the range of dc voltage fluctuation allowed.Finally,the simulation results are given to demonstrate the feasibility and validity of the conclusions.
