摘要
现如今在电网突飞猛进的发展形势下,特高压直流作为一种交直流结合、互换的新型输电模式异军突起。为保证在交流侧电源扰动情况下的稳定运行,以宜宾站在双极低端调试期间交流系统产生扰动后造成双极低端12台换流变压器交流电源故障引发换流变压器冷却器全停等故障,进行事故分析、查找事故原因并提出改进建议。
Nowadays,with the rapid development of power grid,UHVDC is emerging as a new mode of AC/DC combination and switching. In order to ensure the stable operation in disturbance conditions of AC side power source,the full stop faults of converter transformer coolers caused by AC power source faults of 12 converter transformers in bipolar low-end after the disturbance occurred in AC system during the commissioning in bipolar low-end in Yi Bin converter station are analyzed,the causes of the accident are find out,and some suggestions for improvement are put forward.
