摘要（英）：

The invention discloses an auxiliary machine high/low voltage rid-through test method based on a voltage disturbance generator. The test method comprises following steps of S1: accessing the voltage disturbance generator into bus voltage so as to test the voltage disturbance generator; and S2: connecting a to-be-tested auxiliary machine variable-frequency speed control system formed by a to-be-tested auxiliary machine and a frequency converter to the output end of the voltage disturbance generator, simulating voltage disturbance and testing high/low voltage rid-through ability of the to-be-tested auxiliary machine via the voltage disturbance generator. According to the invention, the high/low voltage rid-through ability of the to-be-tested auxiliary machine variable-frequency speed control system accessed to the voltage disturbance generator can be quickly, directly and precisely detected, thereby further detecting working reliability of a power grid.
