As the international standard for substation automation and communication systems, IEC 61850 has become increasingly popular in recent years. Here are some interview questions that will help you better understand this important standard.
Fundamental Concepts of IEC 61850 | IEC 61850 Protocol | IEC 61850 | IEC61850 in Substation | Part-1
Section 8. 1 specifies how the abstract data object and services are mapped to sections 9 and MMS2 of the Manufacturing Messaging Specification. 1 and 9. 2 specifies how to map the sample measured values (in a point-to-point and multipoint direction, respectively) onto an Ethernet data frame. The 9. What has come to be known as the Process Bus is defined in Document 2
IEC 61850 is not just a communications protocol. It is a thorough standard for creating substation automation applications and systems.
A new communication model was required in order to manage a large number of devices and allow them to communicate with one another. The model is IEC 61850 – Communication Networks and Systems in Substations, which was created and standardized.
The following sections of the IEC 61850 standard are crucial to comprehend in order to locate the necessary information:
While the original focus of IEC 61850 was “inside” the substation, discussions are currently taking place to define IEC 61850 for the Substation to Master communication protocol, which is already in use in a number of installations. Additionally, applications that use various IEC 61850 components for wide-area substation-to-substation communication are already in use.
FAQ
How does IEC 61850 work?
To enable communication between IEDs, intelligent instruments, and switchgear, IEC 61850 specifies a process bus. SCADA and HMI systems are present at the station level and are used for substation control and monitoring. IEDs located in a bay level can be communicated with by station level using a station bus.
What are the 3 sub protocols of IEC 61850?
The IEC 61850 protocol is designed to enhance electrical station automation. The standard establishes three principles in order to accomplish this goal: Client-server communication protocols. Multicast communication protocols. Protection and control equipment. Local SCADA. Remote terminal unit using DNP3 or 60870-5-101/104.
Why is IEC 61850 important?
Devices can quickly exchange data and status using GOOSE and GSSE over the station LAN thanks to IEC 61850, which eliminates the need to wire separate links for each relay.
What is the logical node in IEC 61850?
The IEC 61850 object-oriented virtual model’s primary components are logical nodes (abstract data objects), which are made up of standardized data and data attributes. The ACSI is defined by IEC 61850, which generates objects and services devoid of any protocols.
