Model-based approaches to the inter-turn fault diagnosis of electrical machinery cover three main categories: fault modeling, feature extraction, and classification. In this paper, the modeling of a PM generator with the internal permanent short circuit fault under speed variation is presented. For this purpose, the geometrical dimensions, winding arrangement, material, and phase resistance of a typical...
This paper presents various synchronous machine models implemented in the computation of electromagnetic transients. This paper proposes new models for achieving better computational efficiency while maintaining precision. In addition to simple infinite bus analysis, the machine models are also compared for a more sophisticated and practical case study. Precision analysis includes the surrounding...
Simulated model of loss-of-excitation protection for generator is established in Matlab, and then taking advantage of BP neural networks which are most advantageous in recognizing patterns, the operation zone of the active power rotor criterion for loss-of-excitation protecting of generator is recognized. Comparing with conventional microcomputer protection using linear approximation, the result shows...
