Digital Substation is an engineering publication focused on IEC 61850 automation, protection systems, and digital grid intelligence.
Abstract for the patent Merging unit and method of operating a merging unit states the following: A merging unit including at least one input interface for receiving input data characterizing at least one voltage and/or current related to a component of a...
The number of Ethernet switches with integrated IEC 61850-8-1 server increases. Manufacturers do not only implement standard logical node classes according to IEC 61850-7-4 but also those ones introduced by IEC 61850-90-4 technical report. These switches do also support buffered and unbuffered reporting mechanisms. Seems like the closest future is the one where IEC 61850-8-1 (MMS) communications will replace communications over SNMP (being widely used at the moment). This will allow for integration of Ethernet switches in process control systems the same way as it is done with IEC 61850-8-1 pr
When configuring GOOSE and Sampled Values communications it is useful (and sometimes is a must) to have the possibility to check VLAN and Priority tags. Whether your network adapter driver strips tagging or not will define the availability of these parameters not only while using Wireshark, but also other specific tools for analysis of GOOSE and Sampled Values traffic (Omicron SVScout, Omicron IEDScout, GOOSE Inspector, etc.). Today we will see how to make Intel network adapters not to strip this important info.
Updated test register includes a lot more IEC 61850-9-2LE conformant stand-alone merging units and IEC 61850-8-1 ed. 2.0 conformant devices.
In Electric Power Networks of Russia-2014 exhibition MOXA presented DA-820 industrial computer which supports PRP and HSR redundancy protocols. Now process control systems manufacturers and suppliers can use this platform to offer workstations for integration in IEC 61850 station bus networks without redundancy boxes.
Siemens presented the new series of arc-fault protection devices 7XG31. The new series includes 7XG3124 RA24 device which is capable of transmitting GOOSE messages on detection of arc-faults in different compartments of enclosed switchgear. It is possible to...
Much-talked-of Heartbleed bug of open-source OpenSSL cryptography library has been found in ABB Relion 650 series IEDs. Care about this if your IED firmware revision is 1.3.0. Word has been spread by ICS-CERT (Industrial Control Systems Cyber Emergency Response Team).
CIGRE Study Committee B3 will include a new working group - Impact of NCIT applications on HV Gas Insulated Switchgear (WG# B3.39). This subject has not yet been covered by any of CIGRE activities.
Alstom Grid announced update of MiCOM S1 Agile software package (revision 1.1). Update provides users with capability of creating projects with products of recently acquired company Reason Tecnologia (Brazil). Reason Tecnologia product range concentrates on solutions for digital substations.
Cloud-based solutions can not only be used in one's everyday life. Now relay protection engineers can use them while on duty. PowerGrid App allows to perform fault recordings analysis using a web-browser.
CIGRE announced the establishment of new working group as a part of B5 technical committee (Relay protection and automation). New working group will be established in 2014.
Since the UpGrid forum started, many experts were quick to "bury" the exhibition "Electrical Grids of Russia" - the event participation in which is a longterm tradition for electric power engineers all over Russia. We had the feeling that UPGrid - it's more for "white collars", while LEP (as is often simply referred to) - is the place where you meet designers, maitenance engineeres, including specialists from different parts of Russia - those who work directly with the equipment on the ground. And, you know, our assumption looks true. "Digital Substation" prepared a special report from the eve
Open-source world is rich with interesting projects. Today we present a project which offers a possibility of PTP implementation for further studies. Project is called PTPd (PTP daemon) and it offers implementation of the Precision Time protocol (PTP) as defined by the relevant IEEE 1588 standard. PTP Version 2 implements IEEE-1588-2008.
