摘　　要：针对构网型(grid-forming,GFM)风电机组在主动支撑过程中由电磁转矩扰动导致风电机组传动链载荷增加的问题,文章建立了风电机组机械-电气联合仿真的模型。通过这一模型,文章对比了基于虚拟同步机(virtual synchronous generator,VSG)控制的GFM风电机组与基于矢量控制的跟网型(grid following,GFL)风电机组在电网频率突变情况下的载荷特性;同时,还深入分析了VSG控制关键参数对于风电机组传动链载荷的影响。研究结果表明,GFM风电机组在提供频率支撑时,会激发传动链的扭振现象,并且VSG控制的关键参数对传动链载荷具有显著影响。This paper addresses the issue of load increases due to electromagnetic torque disturbances on the drivetrains of gridforming(GFM)wind turbines during active support operation.First,a mechanical-electrical co-simulation model of wind turbines was established.Based on this model,grid-forming wind turbines controlled by virtual synchronous generators(VSG)were compared with grid-following(GFL)wind turbines utilizing vector control,focusing on the load characteristics under abrupt grid frequency changes.Furthermore,a thorough analysis was conducted,digging into the load impact of key VSG control parameters on the wind turbine drivetrains.The research findings indicate that GFM wind turbines can excite torsional vibrations in their drivetrains when providing frequency support,and that the key parameters of VSG control have a significant influence on drivetrain loads.
