The stress was the study of the new methods of calculation the harmonic voltage and the harmonic current, and a new concept of filter ratio to evaluate the actual effect of single harmonic filter was raised considering the background harmonics. As well, the calculation mode of the single harmonic filter was also given based on the concept of filter ratio; it can offer effect data to evaluate the actual filter ratio of the single harmonic filter. At the same time, a method of designing the single harmonic filter was given, too, considering the background harmonics of the power system. In this paper, both the computer analysis and the proven had been done. And the result was shown to be that the voltage aberration and the harmonic current were decreased, and that the actual filter ratio of single harmonic filter was raised. The reason that we must consider the background harmonics when designing a single harmonic filter was also expatiated in this paper.

The results show that, the distribution of magnetic field and electromagnetic force in the aluminum film on the cathode slope are in symmetry to the long axis of the cell, especially the magnetic force is in the same direction as the gravity force, which is in favor of the aluminum discharging from the cathode slope. The highest fluctuation of aluminum pad surface in the accumulation sump is 0.021 m, which still remains within the safe range, and will not cause interpolar short circuit, so a normal operation process could be maintained with the same bus bar configuration as the current 75 kA aluminum reduction cells.
