Abstract
AbstractA current‐voltage composite controller for an arc suppression inverter is designed. The current and voltage at the fault point are reduced by injecting current and regulating the neutral point voltage to completely eliminate the risk of fire and overvoltage caused by a single‐line‐to‐ground fault arc. A cascaded inverter is used, and the effects of the ground parameter measurement, line impedance voltage drop, harmonic current and arc suppression coil on the current control, voltage control and composite control methods are analysed and compared. Finally, software simulations and industrial prototype experiments show that the proposed composite control method is effective and less affected by ground parameter measurement and line impedance voltage drop and has better adaptability.
