  • Publication number: 20250258229
    Abstract: A method of synchronization test of a generator set outlet switch apparatus includes that: prior to a synchronization grid-connected closing of an outlet switch apparatus of a target generator set, a wiring phase sequence of a synchronization apparatus is determined to be correct; then three-phase closings of the outlet switch apparatus are determined to be synchronous; two-side voltage waveform data at a closing moment of the outlet switch apparatus is measured and recorded; and a simulated synchronization closing quality coefficient of the outlet switch apparatus of the target generator set is determined according to the two-side voltage waveform data, and a synchronization closing performance of the outlet switch apparatus of the target generator set is evaluated according to the simulated synchronization closing quality coefficient.

  • Publication number: 20240044967
    Abstract: Provided is a method for determining insulation thermomechanical deterioration of a VPI wire rod of a pumped storage power generator motor. The method includes: periodically performing a cold-heat cycling test on a wire rod, and performing an insulation dielectric dissipation factor testing and a result interpretation of the insulation dielectric dissipation factor testing before and after each period to obtain corresponding data; in response to determining the interpretation result as the data being qualified, continuing to perform the cold-heat cycling test; and in response to determining the interpretation result as the data being unqualified, striking the wire rod with a copper hammer, and using an acoustic acquisition and analysis system to perform signal processing to determine spectral characteristics in a thermomechanical deterioration state as a deterioration criterion.
