摘要
VSC-HVDC系统在实际的运行过程中,不可以避免的会遇到电网电压不平衡的问题。当电网电压不平衡时,直流侧二倍频波动会经过电压换流站传输到相邻的换流站并引起传输功率的波动,从而威胁输电系统的安全运行。
In the actual operation process,the VSC-HVDC system can＇ t avoid encounter grid voltage unbalance problem. When grid voltage unbalance,the second order fluctuation in DC voltage will via the voltage converter station transmission to the adjacent converter station and cause the fluctuation of transmission power,thereby threatening the operation safe of power transmissiom system.
