摘要
基于电化学的相关理论,将铝电解槽等效为电路模型。利用Matlab/Simulink仿真软件,建立了铝电解槽的等效电路仿真模型,研究了阳极炭块下铝液的波动引起极距变化所造成的阳极电流和槽电压的变化。仿真结果显示,正常生产条件下,阳极炭块下铝液的波动情况对流过该支路的电流变化起着主导作用,其它支路阳极炭块下铝液的波动对其影响较小;槽电压的波动频率能够完全反映出各个支路电流的波动频率。
According to the electrochemical theory, the aluminum electrolysis cell is seen as the equivalent circuit. The equivalent circuit simulation model is established using the Matlab/Simulink simulation software. The liquid aluminum surface oscillation under anode carbon blocks can cause interpolar dis-tance change ,and lead to anode current and cell voltage change. This behavior is investigated by the simulation model. The results show that the liquid alu-minum surface oscillation under anode carbon blocks is the dominant factor causing the branch current change, and all the vibration frequency of branch current are contained in the cell voltage power spectrum.
