摘要/Abstract

摘要： 针对低运行工况下直驱风电机群并网出现的次同步振荡（SSO）问题,基于图形化分块建模,在建立风力机、集电线路及电网等独立元件的模型基础上,构造不同集电线路拓扑结构下直驱风电机群的线性化模型。利用特征值分析法和阻抗分析法识别系统中存在的振荡模式,并分析运行工况、电流内环控制参数和风力机数量等因素对SSO频率和阻尼的影响。研究结果表明：d轴电流内环控制参数设置不合理是诱发直驱风电机群SSO的根本原因。在EMTDC/PSCAD中搭建直驱风电机群并网的时域仿真模型,验证了理论分析的正确性。

Abstract: Aiming at the sub-synchronous oscillation（SSO） problem of direct-drive wind turbine cluster grid-connection under low operating conditions, based on the idea of graphical block modelling, the wind turbine generation （WTG）, collector line and power grid are regarded as discrete components. On the basis of establishing detailed models of each component, the linearized model of direct-drive PMSG wind farm under different collector circuit topological structure is constructed. The oscillation modes in the system are identified by using the eigenvalue analysis method and impedance analysis, then the influence of current inner loop control parameters, operating conditions and WTGs number on the frequency and damping is analyzed. The results show that the oscillation phenomenon is caused by improper setting of d-axis current inner loop control parameters. Finally, a time-domain simulation model of direct drive PMSG based on wind farm connected to AC network is built in EMTDC/PSCAD and the simulation results verify the accuracy and validation of the theoretical analysis.

Key words: direct-drive wind turbine cluster, sub-synchronous oscillation, linearized modeling, eigenvalue analysis, impedance analysis
