Instantaneous reactive power control circuit of distribution line

摘要

An object of the present invention is to improve the power factor of a distribution line by controlling a real-time reactive power at the load side by providing an active, high-strength, flexible reactive power control device between the power source side and the load side.;Another object of the present invention is to improve the quality of power by removing harmonic components flowing from the power supply side to the load side.;According to an aspect of the present invention, there is provided a power supply apparatus including a load to which power is supplied through a power line on a power supply side, a voltage detector to detect a voltage on the power line side, a current detector to detect a current of the power line, A controller for calculating and controlling by a line detected by a detector and a current detector, and an inverter for controlling an ineffective power applied to a load by an output control signal of the controller and removing a harmonic component.
