Analyzes The Form Of Harmonic And Afford Several Methods To Prevent Harmonic For Yangqu Compressor Station Of The Shanjing Pipeline

With the development of technology and the gradual increase of industrial production technology, the frequency converter is being used more and more extensive, for example, LCI are very popular. At the same time, the problem of high-frequency harmonics caused by electromagnetic interference and pollution problems is more and more prominent. The Yangqu Compressor Station of the Shanjing Pipeline is using medium-voltage inverter system-driven centrifugal compressors to the long-distance pipeline to the purpose of pressurized gas, it also exists the problems in actual production of harmonic pollution and remediation. By analyzing the Yangqu compressor station in this article on the grid in the voltage inverter harmonic pollution and the impact of power factor, we have found a solution with the actual site and used in the production practice, it is now playing a good role in the safety of electrical equipment and power system.
