Power quality issue with variable speed drive a case study for oil exploration operation in Russia

Abstract

The use of variable speed drive (VSD) has been increased significantly to improve the energy efficiency and conservation. It is estimated that pumping system accounts for nearly 20% of the world's energy used by electric motors and 25% to 50% of the total electrical energy usage in certain industrial facilities [1]. As such, there is a significant incentive to improve the efficiency and performance of pumps.
