  • An electrical substation is a subsidiary station of an electricity generation,transmission and distribution system where voltage is transformed from high to lowor the reverse using transformers. Electric power may flow through severalsubstations between generating plant and consumer, and may be changed involtage in several steps.

  • IEC 61850Data model - Logical Node (LN)

    Definition

    An object which represent a specific function in a domain e.gSubstation automation, Hydro Power plant etc

    A named grouping of data and associated services that is logicallyrelated to a function.

    Smallest part of a function that exchanges data.

    Logical node classes are defined in IEC 61850 7-4

    4 letters are used for defining the logical node class e.g. STMP, XCBR

    First letter represents the function group which belongs to e.g. in STMP, Sdenote is logical node for a supervising function

    A logical node type is created out of classes by adding prefix andinstance number as suffix e.g CNSCSTMP1

    Type 1A TripThe trip is the most important fast message in the substation. Therefore, thismessage has more demanding requirements compared to all other fastmessages. Same performance may be requested for interlocking, intertrips andlogic discrimination between protection functions.

  • IEC 61850Performance requirement Continued

    ABB GroupMay 12, 2015 | Slide 45

    Type 1B OthersAll other fast messages are important for the interaction of the automationsystem with the process but have less demanding requirements compared tothe trip. The performance for automation functions are typically between theresponse time of operators (order of 1 000 ms) and of protection (order of 10ms). This performance is also valid for such messages between a substationsautomation systems and other local systems.
