Introducing a Phase-Advanced Rectifier Circuit for Reduction of Distribution System Reactive Power

摘要

The excessive input of phase-advanced capacitors by customers has been posing a problem to date. To deal with this problem, the installation of phase-advanced capacitors on the low-voltage side was recommended, but it does not presently seem to have produced the expected effect. As a solution, a phase-advanced rectifier circuit, integrated from rectifier circuit built-in equipment and a phase-advanced capacitor, is proposed and the effect of its introduction is discussed. This method is confirmed to be effective for the reduction of reactive power, because the receiving-end voltage and current waveform distortion are improved. In particular, the number of capacitors introduced into the system under light load is reduced.
