Leakage Line Detection Based on Improved Grey Absolute Relation Degree Model


Article Preview

For the defects of traditional grey absolute relation degree, the improved grey absolute relation degree model is presented. Compared with the traditional one, this improved model is more excellent in characteristic, and which takes on consistency and isotonicity; and then the veracity and reliability of grey relation analysis are enhanced. Using this new model to discriminate waveform change rate of zero sequence currents in fault transient course, the leakage line detection method is established. The simulation and lab test indicate that this method can rapidly detect leakage line self adapting in transverse direction, algorithm is simply, and not influenced by random factors.
