数字化变电站过程层通信网络实时性仿真分析
Communication Network Real-time Performance Simulation Analysis Based on Process Layer of Digital Substation
摘要
Abstract
The three-layer communication structure and key technology of digital substation based on IEC 61850 is introduced. The data of process layer of digital substation is analyzed, and the flow of SV packets and GOOSE packets on the basis of IEC 61850-9-2 is analyzed. Combined with a digitized substation project, the OPNET software is used to simulate the IED device end-to-end delay of process layer of digital substation, and the VLAN technology is used to make a comparative analysis in bay. The results show that the switched ethernet can satisfy the network communication of process layer in the digital substation and the VLAN technology can improve the real-time performance of network communication.关键词
