摘要:
针对直驱风电场经串补及柔性直流输电引起的次同步振荡问题,建立了直驱风电场经VSC?HVDC的系统仿真模型。利用该模型模拟了次同步振荡现象,并用频谱分析验证了其正确性。利用时域仿真法,设置不同的场景分析风机网侧换流器的内环控制参数、串补度以及直流侧电容对直驱风机经柔直输电并网系统的稳定性影响。针对减小次同步振荡危害,结合实际工程提出建议。
Abstract:
A system simulation model for direct drive wind farms through VSCHVDC was established to address the problem of subsynchronous oscillation caused by series compensation and flexible DC transmission. The subsynchronous oscillation phenomenon was simulated using this model, and its correctness was verified through spectral analysis. By using timedomain simulation method and setting different scenarios, analysis was made on the influence of the inner loop control parameters, series compensation degree, and DC side capacitance of the wind turbine grid side converter on the stability of the direct drive wind turbine grid connected system through flexible direct transmission. Suggestions are put forward to reduce the harm of subsynchronous oscillation based on practical engineering.
