摘　　要：含恒速异步风力发电机的大型风电场通过含串补线路外送功率时存在次同步谐振问题。以PSCAD/EMTDC仿真软件为工具,建立了适用于风电场次同步谐振分析的大型风电场仿真模型,并在多种运行方式下分析了该风电场通过一串补线路外送功率时的次同步谐振特性和机组扭振特性。另外,还分析了大型风电场与火电厂捆绑送电方式下系统次同步谐振特性。Sub-synchronous resonance may occur when power is transmitted through series compensated lines from large-scale wind farm with constant-speed asynchronous wind turbines. This paper adopted PSCAD/EMTDC simula- tion software and established simulation model for the analysis of sub-synchronous resonance in large-scale wind farm. Thereby, research was conducted on the characteristics of sub-synchronous resonance and torsional vibration when power was transmitted in various operation modes through a series compensated line from a large-scale wind farm. In addition, the characteristics of sub-synchronous resonance were analyzed when the power from large-scale wind farm and thermal power plant were bundled together in power transmission.
