Embodiment Construction
[0046] The specific implementation manner of the present invention will be described in further detail below according to the accompanying drawings.
[0047] The invention provides a high-voltage ride-through test system for wind turbines, which includes a high-voltage generator. The high-voltage ride-through capability of the unit, the single-phase schematic diagram of the high-voltage generator is shown in figure 1 shown by figure 1 It can be seen that the high voltage generating circuit includes inductive reactance X1, capacitive reactance X2, switch K1 and switch K2, one end of inductive reactance X1 and switch K1 is connected to the access point and the other end is connected to the test point, and the capacitive reactance X2 is connected in series with switch K2 to test Point the other end to ground.
[0048] During the test, the switch K1 is disconnected, the switch K2 is closed, and the capacitive reactance X2 provides capacitive reactive current support. The voltage...
