摘要: |
为提高直流系统的可用率和运行效率,祁韶±800 kV特高压直流输电工程极层控制系统配置了两种故障重启动功能,即瞬时性故障重启动和阀组故障重启动。深入剖析了这两种重启动逻辑的触发机制、动作时序和开放条件,着重研究了瞬时性故障重启动逻辑与其他反映瞬时性故障的极区和双极区保护的配合关系,并依据祁韶直流系统调试现场录波图阐明了两种重启动逻辑的动作过程与效果。该研究对现场运行及科研工作有一定的指导和参考意义。 |

Abstract: |
In order to improve the availability and operating efficiency of the DC system, Qi-Shao ± 800 kV UHVDC transmission project pole layer control system is equipped with two kinds of fault restart function, namely the instantaneous fault restart and the valve group fault restart. The triggering mechanism, timing and opening conditions of these two restart logic are analyzed in detail, and the relationship between the instantaneous fault restart logic and other protections reacting transient fault in pole and bipolar zone is studied emphatically, DC system debugging scene recorded wave diagram is referred to illustrate the two restart logic of the action process and effect. The research can provide some guidance and reference significance to the field operation and research work. This work is supported by Science and Technology Project of State Grid Hunan Electric Power Company (No. XDKY-2016-015). |
