Fractal Image Compression Method for Partial Discharge Pattern Recognition

With wide application of the computer network in the electrical power industry, a partial discharge pattern recognition system is required not only to be very capable of recognizing PD patterns, but also to adopt the data compression technique to reduce the telecommunication time, as thereby can improve the rate to classify the PD data stored in remote computer. In this paper the fractal image compression technique is used to design the PD image remote recognition system. The influences of compression errors on recognition results are furthermore studied. It can be shown from analysis of the recognition results of large quantities of the PD samples that the considerably high compression ratio of PD images is achieved in use of fractal image compression technique which improves the corresponding recognition rate to PD images stored in remote computers and make the PD pattern remote recognition system more practicable.
