The modern and high-speed Peer-to-Peer IEC 61850 has opened the chance for planning and developing the sampled values that are supported information exchange among IEDs. Over the method bus network, it’s important to comprehend the transmission responsibility and real-time performance of SVs and GOOSE messages for all-digital IEC 61850 station automation systems (SASs) protection applications to deal with the responsibility, availableness, and settled delay performance we want to propose a process-to-bay level network model for varied network topologies within the OPNET creator platform. In this paper, we check varied topologies in IEC 61850 and packet delay using mesh and star topologies for LAN and WLAN and conjointly compare the performance of projected theme with an existing methodology for numerous parameters for wireless local area network and LAN by varying packet size.
