变电站二次设备就地化系统网络架构探讨

Discussion on Network Architecture of Outdoor Installation Protection System in Substation

针对变电站二次设备就地化背景下设备配置与通信网络面临的问题与挑战,首先提出了变电站二次保护控制设备就地化配置原则,并给出了单间隔保护、跨间隔保护、测控装置、公用采集控制终端等全站二次就地化设备配置方案。在此基础上,提出了基于并行冗余协议(PRP)的制造报文规范(MMS)/采样值(SV)/通用面向对象变电站事件(GOOSE)三网合一网络架构和不依赖交换机的全高可靠无缝冗余(HSR)环网两种变电站通信网络方案,并对其网络性能指标进行了量化评估和比对。

For the installation configuration and telecommunication network problems and challenges confronted by substation secondary device outdoor installation, the principles of the secondary device outdoor installation configuration are proposed first, which include relay protection within both standalone bay and across bays, bay control unit and public terminal, etc. In addition, two telecommunication solutions are also given based on the above, which include two aspects, the first is the network architecture with MMS/SV/GOOSE network all in one based on parallel redundancy protocol（ PRP）, and the second is high-availability seamless redundancy（ HSR） network which is independent of the switch. Finally, network performance is estimated and compared quantitatively.
