Mobile wind turbine generator system high-low voltage ride through test device

The invention provides a mobile wind turbine generator system high-low voltage ride through test device, which is applicable to high-voltage system tests and low-voltage system tests simultaneously, the test device is connected in series between a wind turbine generator system and a power network, and mainly comprises an input breaker, a voltage regulation unit, a bypass breaker and an output breaker. By adopting a transformer secondary side multi-tap voltage regulation mode, for thyristor high-speed switching control as well as a vehicle-mounted container structure, transformer output voltage is changed through controlling the on-ff of a thyristor, and thus a simulation test of different voltage class failures of a wind turbine generator system to be tested is achieved. By using the mobile wind turbine generator system high-low voltage ride through test device provided by the invention, high-low voltage ride through tests can be accomplished simultaneously, and the device has high integration, high reliability and highest economic and technical norms; the device can be applied to testing various types of wind generators, meet high-low voltage ride through test criteria in China as well as countries in Europe and America, and has a wide application range; and the device adopts a vehicle-mounted container structure, adopts a modular design, is convenient to transport and is flexible in testing.
