Summary on Grant Application Form |
|
The project will develop a high frequency model for simulating transformer windings. Physical winding deformations of various nature, severity and locations will be represented accurately in the simulation model and the frequency responses at the measurement terminals will be produced. A number of laboratory windings and a 500kV winding with simulated deformations, located at the Alstom Transformer factory, will be used to validate the simulation model. The simulation results will then be analysed to provide guidelines for evaluating measured frequency responses and increase fundamental understanding of the relationship between measurement results and winding deformation. Features of winding deformation in the frequency responses will be extracted through Wavelet transforms. Fuzzy neural networks will be used to classify deformation status of windings for diagnostic purposes. The large field test database in National Grid Company will be accessed so that measurement and simulation results will be compared and the diagnostic techniques validated. A diagnostic approach to answer the question of location, nature and severity of winding deformation will be provided.
