APPATATUS AND METHOD FOR CONTROLLING STATIC SYNCHRONOUS COMPENSATOR USING PHASE ANGLE AS CONTROL INPUT

摘要

There is provided a control apparatus and a control method for a stationary reactive power compensation apparatus using a phase angle as a control input. A control apparatus for a stationary reactive power compensation apparatus using a disclosed phase angle as a control input includes a capacitor and a converter and uses a command value of a phase angle as a control input, And a controller for calculating a command value of the reactive current based on the command value of the effective current of the static reactive power compensation device, the command value of the DC voltage of the capacitor, A command value calculation unit for calculating a command value of a sine value of a phase angle whose phase of the voltage vector of the phase angle is a value preceding the phase of the voltage vector of the line; A feedback control signal calculation unit for calculating a feedback control signal by using the reactive current fed back from the stationary reactive power compensator and the command value of the reactive current; A differential value of the command value of the phase angle is calculated using the command value of the reactive current, the command value of the effective current, the command value of the DC voltage, the command value of the sine value of the phase angle and the feedback control signal A phase angle differential value calculation unit; And an integrator for integrating the differential value of the command value of the phase angle and calculating the command value of the phase angle.
