Introducing of a Phase-advanced Rectifier Circuit for Reduction of Distribution System Reactive Power
Tadao Aizawa · IEEJ Transactions on Power and Energy · 2009
The excessive input of phase-advanced capacitors by customers has been posing a problem to date. To cope with this problem, the installation of phase-advanced capacitors on the low voltage side was recommended, but 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 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 input into the system under light-load is reduced.
