摘要：
For the problem that the symmetrical surge of grid voltage impacts the voltage and current of stator and rotor of motor, a control strategy of high voltage ride-through (HVRT) of brushless doubly-fed induction generator (BDFIG) is proposed in this paper. The expression of control winding current for BDFIG was deduced. It is concluded that restraining the overcurrent of control winding is not a key problem to be solved for HVRT of BDFIG. The distribution principle of reactive current controlled by BDFIG network-side and machine-side converter was studied. A HVRT scheme for adjusting bus voltage during the fault of grid-side converter and providing dynamic reactive power support to grid was presented. A control strategy for HVRT of machine side converter was put forward. By absorbing a certain amount of inductive reactive power at the machine-side, the CW flux linkage amplitude remains unchanged during the high-voltage fault, so as to reduce the active power fluctuations during the BDFIG fault. The simulation and experimental results demonstrate the effectiveness of the proposed control strategy. © 2022 Editorial Department of Electric Machines and Control. All rights reserved.
