Energy efficiency and electromagnetic compatibility of the frequency converters of pumping units electric drives

Authors: B.Yu. Vasilyev (National Mineral Resources University (University of Mines), RF, Saint-Petersburg)

Key words: pumping unit, electric driver, frequency converter, energy efficiency, electromagnetic compatibility.

The problem of electromagnetic compatibility and energy efficiency in electric drives of pumping units, used in oil pumping stations, is considered. The main advantages and disadvantages of synchronous and asynchronous drives are given. The main ways to improve electromagnetic compatibility and energy efficiency of asynchronous drives are analyzed.
