Single Line Diagram Electrical House Wiring - Some other notion for representation of the method bus at the sld is to depict the mu as an optical auxiliary transformer. This retains the practice of displaying a one-to-one courting among analog dimension and the enter to the ied. As a result of those factors, the limitations of the legacy documentation system and the need to file the inner relay common sense together with the outside logic, has driven many utilities to exchange the manner that protection relay logic is depicted on the slds.

The single line diagram (sld) is the maximum basic of the set of diagrams which might be used to report the electric functionality of the substation. Its emphasis is on communicating the functions of the energy gadget and the associated protection and control system. With the appearance of the microprocessor primarily based relay, one output touch may be the composite end result of the operation of more than one measuring gadgets combined with timer and multiple conditional conditions. None of this inner complex logic is shown on the everyday manipulate schematic.

In addition, because it's miles current data it is not introduced serially to the ieds as it might if it have been a ct, instead, the statistics is introduced in parallel to the ieds. Labeling could allow the association of the characteristic to the ideal mu. With the logic for the safety and manage circuits in addition to the primary energy circuits, and the cutting-edge and voltage circuits being proven on the sld. The sld may be used to understand the systems being implemented inside the substation.

With an mu, you can most effective tell the set of data that may be feeding the ied, not what information it is using. The protecting functions that the ied is performing will not be obvious from the relationship on my own. Application of iec 61850 technique bus calls for a rethinking of the way relay circuits are to be shown on an sld. The merging unit (mu) in a technique bus implementation takes analog inputs of voltage and modern-day and digital inputs and converts them to iec 61850 protocol.
