Research on the Control Method of High Power APF for Oil Drilling Rig

Abstract:

The wide use of oil drilling rig brings nominated economic profits for oil drilling industry. However, it will bring about great quantities of harmonic current to the grid, lowering the power quality and reliability of the power grid. Meanwhile, harmonic currents will have a deteriorated influence to surrounding electrical equipment and grid. This paper studies the distribution characteristics of the harmonic current in the oil industry and puts forward a control strategy aiming for improving stability and reliability of the power supply system. This paper also proposes an algorithm for detecting harmonic current based on time domain transformation and control strategy based on two cascade (voltage and current) control loop. Experiment and simulation results validate the proposed control strategy.
