Control method and control device of inverter and wind generating set

The invention provides a control method and device of an inverter and a wind generating set. The control method of the inverter comprises the steps that first active current output by a new energy unit comprising the inverter is obtained; limiting the amplitude of the first active current according to the operation state of the new energy unit to obtain a second active current; determining a first reactive current according to the operation state of the new energy unit; obtaining a control voltage component based on the second active current and the first reactive current; and controlling the inverter to work based on the control voltage component. According to the control method disclosed by the embodiment of the invention, the overvoltage suppression effect of the sending end system can be improved. 本公开提供一种逆变器的控制方法、控制装置及风力发电机组，该逆变器的控制方法包括：获得包括逆变器的新能源机组输出的第一有功电流；根据新能源机组的运行状态对第一有功电流进行限幅以获得第二有功电流；根据新能源机组的运行状态确定第一无功电流；基于第二有功电流和第一无功电流获得控制电压分量；基于控制电压分量控制逆变器工作。根据本公开的实施例的控制方法能够改善送端系统的过电压抑制效果。
