Abstract
An integrated high and low voltage ride through test system, comprising a primary system and a secondary system; the secondary system controls the primary system to realize information interaction, and is connected to a power grid and a wind generation set via an inlet wire switch cabinet and an outlet wire switch cabinet of the primary system; the integrated high and low voltage ride through test system actually simulates voltage drop and rise characteristics in a power grid failure, ensures that when generating a low voltage and a high voltage, the change of a voltage phase angle and power quality are consistent with actual power grid failure characteristics, and enables coherent low voltage and high voltage ride through capacity testing on the wind generation set in a primary test process. The test system employs a structural design of a mobile vehicle-mounted container, with all component modules thereof being integrally installed in a standard container, free from the impact of weather and geographical environment, being able to conduct all-weather on-site testing in any wind farm, and having good environment adaptability.
