Description

Various cross current compensators (CCC) are used to restrain wattless cross current which flows between generators connected parallel in such as the Ship's A. C. power system.<BR>When load power factor is low, these CCC's generally reduce the bus voltage, and thus the effect of CCC's opposes to the effect of the automaticvoltage regulator (AVR) . This means that the more cross current compensation is intended, the worse becomes the regulation of the main bus voltage, and the regulation will be larger than that at single operation.<BR>We have used the differential current transformer (DCT) for these CCC circuits, and have confirmed by experiments on the marchant ship that the voltage drop at the parallel operation are remarkably reduced.<BR>We also confirmed that the analytical results of the effects of the DOT Constant coincide to the experimental results.<BR>The DCT can be used for any AVR system and the voltage regulation of the bus can be kept within ± 1 % in both cases of single and parallel operation by using the DCT.
