What is DD IEC/TS 61850-2- Communication networks and systems in substations about?
DD IEC/TS 61850-2 is an international standard that discusses communication networks and systems in substations.
DD IEC/TS 61850-2 applies to Substation Automation Systems (SAS). DD IEC/TS 61850-2 defines the communication between intelligent electronic devices (IEDs) in the substation and the related system requirements.
DD IEC/TS 61850-2 contains the glossary of specific terminology and definitions used in the context of Substation Automation Systems within the various parts of the standard.

Why should you use DD IEC/TS 61850-2- Communication networks and systems in substations?
A bay is a powerline in a substation that consists of intricately connected subparts with some common functionality. Examples are the switchgear between an incoming or outgoing line, and the busbar, the bus coupler with its circuit breaker and related isolators and earthing switches, and the transformer with its related switchgear between the two busbars representing the two voltage levels.
The bay concept in accordance with DD IEC/TS 61850-2 applied to 1½ breaker and ring bus substation arrangements by grouping the primary circuit breakers and associated equipment into a virtual bay. These bays comprise a power system subset to be protected, for example, a transformer or a line end, and the control of its switchgear that has some common restrictions such as mutual interlocking or well-defined operation sequences. The identification of such subparts is important for maintenance purposes (what parts may be switched off at the same time with minimum impact on the rest of the substation) or for extension plans (what needs to be added if a new line is to be linked in). These subparts are called ‘bays’ and are managed by devices with the generic name ’bay controller’ and have protection systems called ‘bay protection.’ DD IEC/TS 61850-2 assists with bay level functions which are those functions that use the data of one bay and act on the primary equipment of that bay. Bay level functions communicate via logical interface 3 within the bay level and via the logical interfaces 4 and 5 to the process level, i.e., with any remote input/output or with intelligent sensors and actuators. DD IEC/TS 61850-2 describes the conformance test which relates to checking data flow on communication channels ls in accordance with the standard conditions concerning access organization, formats and bit sequences, time synchronization, timing, signal form and level and reaction to errors. The conformance test is carried out and certified and standard or specifically described parts of the standard. The conformance test is carried out by an ISO 9001 certified organization or system integrator. DD IEC/TS 61850-2 states the task(s) performed by the substation automation system i.e., by application functions. Functions exchange data with other functions. Details are dependent on the functions involved. Functions are performed by IEDs (physical devices). A function is split into parts residing in different EDs but communicating with each other (distributed function) and with parts of other functions. These communicating parts are called logical nodes. DD IEC/TS 61850-2 aids the subnetwork, substation automation system, supporting tools, system integrator, system life cycle, system parameters, system test, and telecommunication environment.
DD IEC/TS 61850-2 assists with all the necessary details for the communication networks and systems in substations, system parameters, test methods, and procedures, environment suitable for tests when performed, that can help you expand your business globally.
Overall, DD IEC/TS 61850-2 is useful as it provides guidance on communication networks and systems in substations which can be beneficial for your business
