Digital breaker signals. The different equipment manufacturers have to include the communication protocols required by the IEC standard and they have to adapt their tools to work with the normative files.
They need to know how to identify the capabilities of the IEC equipment the communication services available and the information exposed in the logical nodes to be able to automate the system to fulfil the required specification. They also need to know how to identify if a device provides the required functionality. The utilities need to know the main features of the standard to apply it in the specification of their substations. There are different degrees of commitments:.
The GOOSE messages must be documented and the devices that use that information identified to check their status during the maintenance tasks. IEC includes a test mode used to check the equipment functionality without disturbing its normal operation. The utilities need to evaluate if the test mode fulfils their requirements and to specify its inclusion in the required equipment.
Of course, its use should be included in the maintenance procedures. Originally the IEC standard applied only to the automation of the electrical substations. Nowadays several groups within IEC are working to define an information model to automate several other energy system areas as:. In we are using IEC edition 2 and working in its first amendment 2. Edition 2 includes:.
The amendment to the edition 2 edition 2. Your Name required. Company required. Your Email required. Avoiding proprietary protocols and being able to integrate equipment of different manufacturers.
This concept is called interoperability. Using technologies that can reduce the cost in wiring and engineering time. Seeking for improvements in the commissioning and maintenance tasks. In order to achieve this goal the standard develops 3 principles: The definition of a unified information model with a naming hierarchy and specific data structures to use in any compliant device.
Vendors are request to identify the same concepts with the same name and they must use a common format to build their information. This characteristic reduces the time looking for information, the errors and the format conversions. Imagine having hundreds of manufacturing plants scattered across the country, all with their own brands of devices communicating in a wide spectrum of protocols. Now imagine that in order for these plants to function efficiently and effectively, there is a need for these plants to communicate with each other BUT the protocols are not interoperable; the devices are not meant to communicate with each other natively.
Replace these manufacturing plants with substations and you have an idea what is happening throughout the world with regards to power transmission and distribution. In order to maintain power quality and reliability, substations need to communicate with each other. However, with the many protocols, much engineering work is required. Furthermore, with renewable energies and micro-grids introducing a different set of manufacturers, protocols and electricity capable of disturbing the stability of grid-supplied electricity e.

It has a standard data naming convention, self-describing devices, virtualized modeling of logical devices, and a common language to configure devices. The goal of this approach is to have complete interoperability between devices and less project engineering and commissioning time.
