Calculation of the Filter Parameters for the Aluminum Electrolyzation Rectifier
In this paper, the rectifier transformer third winding to install high-pass filter have been studied, and the calculating method of the high-pass filter parameters have been put forward. The power factor and the filter parameter of three series rectifier unit in a company are calculated, then its discovered that the practical operating parameter tallies with theoretical result and the practical power factor fits with the theory in one of the series of fdters, and this attain the system requisition, so then demonstrates the parameter calculation method in this paper is correct. It is suggested that the capacitance capacity of the high-pass filter of the third winding in aluminum electrolyzation rectifier unit should be calculated according to meeting to the displacement factor compensation requisition, that is, cut-off frequency: 3th harmonic, resonance frequency: 7th harmonic, quality factor: 5 or so, m: 0.2 or so, resistance: ≤10Ω. The greater the filtering resistance, the stronger the harmonic impedance, which will affect the harmonic filtering effect.
