CURRENT CONTROL APPARATUS OF DISTRIBUTION STATIC COMPENSATOR CONSIDERING NONLINEAR LOAD

摘要

PURPOSE: A current control device of a distribution static compensator is provided to improve a current control function by controlling a fundamental wave and a harmonic wave of a command current through a proportional resonance controller and a repetition controller. CONSTITUTION: A proportional resonance controller(32) controls a fundamental wave of a command current. A repetition controller(33) is connected in parallel to the proportional resonance controller. The repetition controller controls the harmonic wave included in the command current. An error production unit(31) outputs the error of the load current and the command current to the proportional resonance controller and the repetition controller. An adder(34) outputs the current control signal of a distribution static compensator by adding the output of the proportional resonance controller to the output of the repetition controller.
