Petroleum active power filter used in petrochemical industry


2021-02-08

Due to production needs, there are a large number of pump loads in the petrochemical industry, and many pump loads are equipped with frequency converters. The large number of applications of frequency converters have greatly increased the harmonic content in the petrochemical industry’s power distribution system. The rectification link of the frequency converter is to use 6-pulse rectification to convert alternating current into direct current, so the generated harmonics are mainly the 5th, 7th and 11th harmonics.
