S-SCDN Concept and Its Situation Awareness Visualization Application Scenario Analysis

Substation centralized medium voltage distribution network (SCDN), makes the large-scale complex medium voltage network into a dynamic radial network with a fixed static topology and a central substation as a unique power supply source. A novel concept of “Supply Region of substation centralized medium voltage distribution network (S-SCDN)” is proposed to generate a “one map” as the core technology of the “urban distribution network brain”. The prototype of SCDN and S-SCDN and single line diagram prototype are proposed, and their basic characteristics are studied. Then, the application scenario analysis based on S-SCDN single line diagram including a situation awareness dynamic visualization platform under SCDN/S-SCDN concepts is also proposed, which indicates that S-SCDN single line diagram provides a new analysis tool for urban complex distribution network with a wide application.
