Abstract

Model-based approach along with few signal processing techniques like EMD is used for diagnosing synchronous generators. Maintenance is essential for machines, and many industries started to rely more on condition-based and preventive maintenance rather than scheduled and risk-based as it reduces cost and also ensures safety. To reduce the complexity and cost, experimental test rig requirement can be eliminated using Maxwell software. DEKF is used as it has two cascaded EK filters; it can estimate both state and parameters. Residual and IMF3 together will work as a reliable fault signature which helps in differentiating the stator inter-turn fault and a pseudo stator fault.
