1. A method for synchronization test of a generator set outlet switch apparatus, comprising:
prior to a synchronization grid-connected closing of an outlet switch apparatus of a target generator set, determining whether a wiring phase sequence of a synchronization apparatus is correct;
in a case where the wiring phase sequence of the synchronization apparatus is determined to be correct, determining whether three-phase closings of the outlet switch apparatus are synchronous;
in a case where the three-phase closings of the outlet switch apparatus are determined to be satisfied synchronism, measuring and recording two-side voltage waveform data at a closing moment of the outlet switch apparatus; and
determining a simulated synchronization closing quality coefficient of the outlet switch apparatus of the target generator set according to the two-side voltage waveform data, and evaluating a synchronization closing performance of the outlet switch apparatus of the target generator set according to the simulated synchronization closing quality coefficient.
