| Abstract: | Based on the study on the diagnosis techniques about turbine-generator rotor's turn-to-turn short circuit, the research coil method is selected.A set of on-line and real-time diagnosis system is developed.The TMS320VC33 chip is used as the core and the wavelet transform technique is applied to the power system fault diagnosis. The dynamic simulation experiment is conducted. The simulation result proves that the developed diagnosis mechanism is effective. |
