Penggunaan Software Wireshark untuk Monitoring dan Troubleshooting pada Komunikasi Client Server IEC 61850

Abstract

Transmission data (status, measurement, control) between Substation Automation Systems (SAS) is different from Conventional Substation. Conventional Substation uses cables (hardwired) to transmit data, while SOGI transmits data using data communication via an Ethernet network, using IEC 61850 protocol. IEC 61850 protocol is currently widely used for communication within substations. Currently SAS has been widely implemented in PLN, where IEC 61850 protocol is the mandatory protocol used in SAS. SAS consists of various kinds of equipment such as: server, gateway, Intelligent Electronic Devices (IED). In SAS maintenance, it is necessary to monitor and troubleshoot IEC 61850 communications to ensure data is sent between the equipment. One of the IEC 61850 communications that is often used is client server communication (report). To monitor IEC 61850 communications, an IEC 61850 protocol analyzer is needed such as IED scout from Omicron, IEC 61850 Test Suite Pro from Trianglemicroworks, IEC 61850 Protocol Test Tool from Ase systems or other IEC 61850 protocol analyzers. All protocol analyzers are paid, while not all PLN units have protocol analyzer software. One alternative software that can be used is Wireshark, this free software can be used to monitor all Ethernet-based communications, including IEC 61850 protocol. In the tests carried out in this research, it can be concluded that wireshark can be used to monitor IEC 61850 communications using “mms” filters and laptop for monitoring is connected on the switch's ethernet port which has been mirrored to the SAS equipment port which communicates via IEC 61850 client server communication.
