چکیده
This paper presents a new approach to identify distributed parameters of a lumped-element model for a power transformer. A simplified circuit of a lumped-element model is developed to calculate frequency responses of transformer windings in a wide range of frequency domain. In order to seek optimal parameters of the simplified circuit of the transformer, an intelligent learning technique, based on particle swarm optimiser with passive congregation (PSOPC), is developed to identify model parameters using frequency response measurements. Simulations and discussions are presented to explore potentials of the developed approach. Index Terms – Transformer modelling, winding deformation, particle swarm optimiser, passive congregation.

Periodic noise widely appears in raw images and is often accompanied with white noise. The removal of such compound noise is a challenging problem in image processing. To avoid using the time-consuming methods such as Fourier transform, a simple and efficient spatial filter called optimal soft morphological filter (OSMF) is proposed in this paper. The filter is a combination of basic soft morph...
