输电线路两端受控电压源失谐引发功率振荡的机理分析OA北大核心CSTPCD
Mechanism Analysis of Power Oscillation Caused by Disharmony of Voltage Source Controlled-units at Both Sides of Transmission Line
随着构网型(grid-forming,GFM)变流器技术的成熟以及在维持弱电网稳定性方面的优势,其将广泛应用于新型电力系统中的柔直、储能等并网单元.受分布式GFM变流器频率测量和控制精度差异及电网频率时空分布特性的影响,易发生交流输电线路两端基于GFM型变流器的电压源型受控单元(voltage source controlled-unit,VSCU)输出频率长时间不一致的失谐现象.失谐是否会进一步引发线路异常的功率振荡问题,亟待研究.首先,该文基…查看全部>>
As the technology of grid-forming(GFM)converters matures,offering advantages in maintaining stability of weak network,these converters will be widely applied to grid-connected units connected to new power system,such as flexible direct current transmission system and energy storage.Due to the difference in performance of GFM converters'strategy under distributed control,frequency measurement accuracy at each node,and spatiotemporal distribution characteristi…查看全部>>
