摘要
为增强云-贵互联工程三端直流保护系统的健壮性和稳定性,除和两端直流工程一样,在每两站之间使用两路冗余点对点通信方式外,还要求当其中两站的两条冗余线路全部通信异常时,两站之间控保系统的状态数据可以通过另一站转发达到不中断。基于此,本文对两个可行方案的网络架构设计和工作机制进行阐述,然后对其各自的优缺点进行了分析。最后,确定了三端站间通信方案,并提出今后需进一步研究的方向。
In order to enhance the robustness and stability of the three-terminal HVDC control&protection system of Yun-Gui interconnection project.In addition to the use of two redundant point-to-point communication modes between each station,as with the normal HVDC project,it is also required that when the two redundant lines between two stations are all communication abnormal,the state data of the control&protection system between the two stations can be forwarded through the other station to achieve no interruption.Based on this,this paper expounds the network architecture design and working mechanism of two feasible schemes,then analyzes their respective advantages and disadvantages.Finally,determines the communication scheme between three terminal,and the direction of further research is proposed.
