摘要
根据天广直流工程投运初期的系统实际 ,研究有关操作和故障情况下换流站的内部过电压问题。预测换流站主要设备的工况 ,如交流母线、直流线路、中性母线、直流滤波器等设备的过电压水平 。
This paper investigates internal overvoltage in Tian-Guang HVDC transmission system under various operation and fault conditions. The behavior of main devices at converter stations are simulated, the maximum overvoltage on AC buses, DC lines, Neutral Buses, DC filters are calculated. Based on these studies, some countermeasures against high overvoltage in some device are discussed.
