Process Level Network of Intelligent Substation Research Based on OPNET

智能变电站过程层网络肩负全电气量采样值、高压一次设备状态检测值、保护与控制IED跳闸控制命令的传输任务。在过程层采样值、GOOSE、IEEE 1588三网合一的基础上,利用OPNET仿真软件,应用虚拟局域网(virtual local area network,VLAN)和基于通用属性注册协议(GARP)的组播注册协议(GMRP)相结合的报文过滤技术对三网合一组网方式的过程层网络进行了仿真分析,结果表明智能变电站过程层网络性能稳定可靠,满足实时性要求,是可行的。

Process Level network of intelligent substation is responsible for full electrical sample values,a high-pressure equipment state value,protection and control of IED trip commands transmission task.On the basis of sampled values of process lever,Generic object oriented substation event（GOOSE）and IEEE 1588 three nets unite as one,using the virtual local area network（VLAN）and the group multicast registration protocol（GMRP）packet filtering technology based on GARP,carried out a simulation analysis on the process level network of three networks by means of OPNET software.The result verifies the feasibility of the proposed scheme.Its performance specifications fully meet the requirement of real-time,and the technical solutions are reliable.
