基于OPNET的SMV与GOOSE报文共网传输的数字化变电站技术研究与分析

SMV and GOOSE Packet Communication in Common Network of Digital Substation Based on OPNET

介绍了现有数字化变电站的2种组网模式。分析了IEC 61850-9-1的采样值点对点传输方案以及IEC61850-9-2的采样值网络传输方案;提出了一种应用VLAN技术的IEC 61850-9-2采样值网络和GOOSE网络共网传输的方案,从技术,经济角度分析了其可行性;并对过程层的采样值,GOOSE数据报文进行了流量分析。结合某数字化变电站试点工程,采用OPNET仿真软件对共网传输中IED设备的端到端延时进行了仿真分析,结果表明采用VLAN技术的共网传输方案可行。

Two networking modes are presented for digital substations.The SMV point-to-point transmission mode based on IEC 61850-9-1 and the SMV network transmission mode based on IEC 61850-9-2 are both analyzed.A VLAN-based common network transmission scheme is proposed for IEC 61850-9-2 SMV and GOOSE,proved practical technically and economically;the traffic analysis is made about SMV and GOOSE packets in process level.In combination with a pilot digital substation project,simulation analysis about end-to-end delay of IED in common network transmission is conducted by means of OPNET software,which verifies the feasibility of the proposed scheme.
