Digital Substation is an engineering publication focused on IEC 61850 automation, protection systems, and digital grid intelligence.
IEC TC 57 proposes a new work item (57/1768/NP) IEC 61850-7-7: Communication networks and systems for power utility automation – Part 7-7: Basic communication structure – Machine-processable format of IEC 61850-related data models for tools (proposed 61850-7-7). Closing date for voting: 2016-11-25.
Newton-Evans Research Company disclosed some of the findings of 2016 North American Protective Relay Marketplace report. The findings in this report are based on survey responses received from 79 electric utilities that include 16 investor-owned, 28 public power, 26 cooperatives, 4 electric power consulting groups, and 5 Canadian electric utilities.
A local area network is critical infrastructure in a digital substation. Experts in the area of relay protection and automatic as well as automated process control systems run into it with increasing frequency, while the number of questions such as, ‘How to design it?’, ‘How to maintain it?’, ‘How to evaluate its security and effectiveness?’ only increases.
IEC 61850 standard is becoming more and more widespread in electric power industry today. А great number of installations and R&D activities involve application of IEC 61850 and many vendors offer IEC 61850 compliant products with less alternatives every other day. These circumstances call for the improvement of engineers’ competence. We are glad to invite engineers of your company to participate in the unique 5-day training course – Development, design, commissioning and maintenance of IEC 61850 compliant systems, which will take place in Rome (Italy) on November 7-11, 2016.
Using which IEC 61850 services fault recorders in digital substations must acquire data? How the architecture of fault recording systems must change in digital substation? Experts talk.
SIPROTEC 4 and SIPROTEC Compact users are recommended to check EN100 module firmware.
GOOSE-messaging has been covered a lot in many technical papers and to add anything valuable to the subject is rather difficult. But we will try. And functional constrained data will help us with that.
There are several applications that can be used for monitoring IEC 61850 traffic in the Ethernet network. But there is one free-of-charge option everyone should know about.
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
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.
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.
