摘要

为了减少直流闭锁后功率恢复和重启动过程对电网稳定性影响

以一起山火导致的锦苏直流单极闭锁事件为背景

分析了故障发展时序

研究了此次单极闭锁发生过程中保护动作和重启动情况

研究了线路突变量保护动作原理和直流重启动逻辑。基于实际控制保护装置的RTDS数模混合仿真平台

对此次单极闭锁事件进行了反演

将仿真结果与实际录波进行了对比。结果表明:保护装置的动作确实反映了线路故障。

Abstract

To reduce impact of restoration and restart process after DC blocking on grid stability

the unipolar blocking event of Jin- Su UHVDC Transmission Project caused by fire is taken as an example. The fault development sequence is analyzed. The protection action and restart during the unipolar blocking

as well as the principle of mutation protection action and the logic of restart

are studied. Based on the simulation platform RTDS of UHVDC control and protection

the unipolar blocking event is displayed

and the simulation result is compared with the actual recorded wave. The results show that the operation of the protection device reflects this fault.
