Improvement on Application of Gray Correlation Analysis in Intelligent Transformer Area Recognition

Based on the voltage eigenvalues of the intelligent electricity meter, a new method, which will improve the gray correlation analysis, for recognizing the transformer area is proposed. This method will overcome the existed disadvantages and implement the intelligent recognition through analyzing the correlation of line voltages between the unrecognized or cross-zone electricity meter and the recognized electricity meter. The test result shows this method is able to accurately identify the transformer area under complex and complicated environmental conditions which is of great practical value.
