The intelligent transformation of digital substations needs to realize the intelligent transformation of primary equipment status, advanced functions and auxiliary systems. The emphasis of the transformation is the intelligent transformation of intelligent advanced applications, primary equipment and auxiliary equipment.
(1) Primary system transformation: Add the key primary equipment status monitoring function to the intelligent unit, and the status analysis results can interact with related systems based on DL/T 860 “Substation Communication Network and System (All Parts)” (ie IEC 61850).
(2) Secondary system transformation: The bay level optimizes and integrates equipment functions, simplifies secondary wiring and network; station control level functions, intelligent advanced applications and auxiliary equipment intelligent transformation are the same as conventional station transformation.
