Distribution System Analytical
Data (DSAD) WG
Roger C. Dugan
Electrotek Concepts
Knoxville, TN
July 1998
R. C. Dugan, DSAD Working Group, July 98
Scope
• Develop a data dictionary for
Distribution System Analytical Data
– Based on form already established by PSAD
Working Group
– Envisioned as continuing effort spanning many
years
• Due to huge volume
• New product introductions
R. C. Dugan, DSAD Working Group, July 98
Scope, cont’d
• Establish dictionary first for those
quantities most commonly used in
power flows, voltage drops, and other
similar calculations. (est. 2 yrs)
• Tackle control quantities, dist. Planning
quantities, etc. (est. ad infinitum)
R. C. Dugan, DSAD Working Group, July 98
PSAD vs DSAD Data
• PSAD is more concerned with control
center and G&T planning data
• DSAD will add definitions for data used
for distribution systems analysis
• May have to duplicate some quantities
• DSAD volume is expected to be higher
due to greater variety of equipment
R. C. Dugan, DSAD Working Group, July 98
PSAD - DSAD Conflicts
• PSAD in MW, MVA; DSAD will be kW, kVA.
• The PSAD makes very extensive use of per unit
values while distribution data uses it less
• Some Z’s are described in per unit on System MVA
base, which is sometimes not used in Dist. Analysis
– Lines
– Capacitors
– Some machine data
• (Transformers are done compatibly with DSAD
concepts.)
