摘要：【中文】本发明公开了一种风力发电机组辅助装置及基于该装置的运行方式，装置的一端串联到风力发电机组电机定子输出端，作为电机定子的一部分，另一端串联到原风力发电机组电机定子输出端应连接的接线端子，主要包括三相直流电阻器，开关器件及其控制模块；正常运行时，开关器件开通，短接三相直流电阻器；电网故障，比如电网电压跌落时，通过控制模块关断开关器件，投入三相直流电阻器；电网故障结束，待机组进入稳态运行后，通过控制模块开通开关器件，切出三相直流电阻器。本发明可以实现风力发电机组电网故障穿越更安全、更可靠、更经济的目的，具有良好的实用性。 【EN】The invention discloses a wind generating set auxiliary device and an operation mode based on the device, wherein one end of the device is connected to the output end of a motor stator of a wind generating set in series to be used as a part of the motor stator, and the other end of the device is connected to a wiring terminal which is connected with the output end of the motor stator of the original wind generating set in series; when the three-phase direct current resistor runs normally, the switching device is switched on and is in short circuit with the three-phase direct current resistor; when the power grid fails, such as the voltage of the power grid drops, the switching device is turned off through the control module, and a three-phase direct current resistor is switched on; and after the power grid fault is ended and the standby group enters into steady-state operation, the switching device is switched on through the control module, and the three-phase direct current resistor is switched out. The invention can realize the purpose of safer, more reliable and more economical grid fault ride-through of the wind generating set, and has good practicability.
