Load / Voltage Analysis Alphabet soup:
– Real-time– Historical– Projected– Peak– Instantaneous– Average– Changing
….the differentiator between these is…Time

Load Duration Curves Time-Series data converted to time-independent data
– Simplifies analysis– Non-engineers understand it
17© 2008 OSIsoft, Inc. – All Rights ReservedPI T&D Users Group
Load Duration Curves Demonstrate peak loads, duration of peaks and how
many hours load limits are exceeded
18© 2008 OSIsoft, Inc. – All Rights ReservedPI T&D Users Group
Load Duration Curves Rearrange data: load-dependent, not time-dependent

Non-SCADA Asset Loads Substation C has no electronic metering. Can I get
load profile data for it?– My Power Flow suggests 1 MW losses total for line
sections 1-4 at peak load
