摘　　要：直驱型风电场经高压直流输电工程送出系统曾发生由于次同步振荡(subsynchronous oscillation,SSO)导致的事故。首先通过分析直驱风电场经HVDC送出系统主导模态的参与因子,确定了次同步阻尼控制器(subsynchronous damping controller,SSDC)的最佳安装位置。另外,提出了SSDC的参数设计方法,研究了SSDC的结构和时域性能指标,基于遗传算法(genetic algorithm,GA)设计了参数优化算法。在PSCAD/EMTDC仿真平台的验证结果表明,本文设计方法可有效抑制次同步振荡。The subsynchronous oscillation(SSO)problem has been captured in power system with PMSG based wind farm connected to HVDC transmission system.In this paper,the installation position of the subsynchronous damping controller(SSDC)is determined by analyzing the participation factors of the dominant mode.Besides,a design method of SSDC is provided.The configuration and the performance indicator is discussed,and then the optimization algorithm is developed based on genetic algorithm and electromagnetic transient simulation.Finally,the proposed design method is validated by simulation in PSCAD/EMTDC.
