High and low voltage ride through an integrated test system

The present invention provides an integrated test system through high and low voltage, the test system includes a primary system and a secondary system, the secondary system to achieve the primary system control information exchange, and by one into the line system and the outlet switchgear Switchgear grid connected wind turbine. The integrated low voltage across the test system can truly fault simulation grid voltage drop and rise characteristics, while ensuring a low voltage and high voltage is generated, the phase angle of the voltage change is consistent and real power quality characteristics of grid fault, it is possible a testing process to realize the wind turbine to carry out a coherent low voltage and high voltage ride-through capability detection. This test system uses a mobile container-board design, all its components are integrated module installed in standard containers, not climate and geographical environment impact, to carry out field tests around the clock in any wind farm, with a high environmental adaptability.
