Abstract

The wide application of inductive loads in the mine industry introduces the harmonic current to the electric gird, which pollutes the power grid and further do harm to the electric equipment. To resolve this problem, a novel NPC-type three electrical level reactive power compensator is presented in this paper. The circuit structure and operating principle are first studied, based on which, the dynamic mathematic model is built. With the introduction of current feedforward control strategy and SVPWM, the dynamic decoupling strategy between active and reactive current is proposed. For the decoupled reactive subsystem, the PI regulator is also designed to ensure the closed-loop stability. The MATLAB/Simulink based simulation model of the proposed control system is constructed, and the corresponding simulation and experiments are preformed, whose results demonstrate the correctness and effectiveness of the proposed strategy.
