According to analyze damage of current aluminum electrolytic rectifier, one second order high pass filter was presented, which can complete harmonic suppression and power compensation. At the same time, principle and parameters computation method of it were given in the paper. Experiment results proved, it could reduce harmonic currents and increase power factor effectively if the according methods were used to design filter, it is obvious economic effects and good application prospects in the aluminum electrolytic enterprises. With the current power system harmonic pollution becoming serious, its damage is given great concern by the electrical profession. The aluminum electrolytic rectifier is great harmonic source in power system, which output currents to it, and which bright large sum of extra power rate to enterprises according to current power rate metering method[1].Furthermore, it can reduce rectifier units power factor. Accordingly, it is necessary to complete harmonic suppression and reactive power compensation for power system supplying good quality electrical energy. The given company 160KA aluminum electrolytic rectifier was presented for the experiment object in our country in the paper. According to analyzing its structure and parameters, one design method of second order high pass filter was given, which could complete harmonic suppression and power compensation. After the filter was used, it not only could suppress harmonic current, but also could increase power factor to reasonable level so as to reach anticipation effects.
