Through the analysis of the electromagnetic properties for the rotor coil of turbine generator, we obtained the main magnetic field variation characteristics for the rotor winding and put forward the short circuit fault between rotor inter-turns causing the potential difference and circulation between the parallel branches of generation stator winding spectral method was applied on the spectrum analysis...
This paper had built inter turn short-circuit fault diagnose system of steam generator rotor windings based on the fault criterion of rotor inter turn short circuit on-line identification. The frame of diagnose system is introduced, and then the long-distance rotor inter turn short-circuit diagnose system which based on B/S module is built by combining advanced VB.net technique's Web service and SQL...
The electromagnetic characteristic and rotor vibration characteristic of turbine-generator are analyzed when rotor windings inter-turn short circuit fault has happened. This paper also gets relevant characteristic parameters. Based on characteristic parameters, RBFNN (radial basis function neural network) can be adequately trained and diagnosis rotor windings inter-turn short circuit. RBFNN is independent...
