Assets, data and time semantics

#Map metering records to assets and consuming processes

Link energy records to assets, measurement boundaries and consuming processes. Explain who is served and which task is affected by a state. Separate asset types from site instances so common calculations can be adapted.

Distinguish energy flows, data associations and work handover. A relationship diagram helps explain connections; engineering links, timing and actual effects require records and professional review.

#Check units, measurement boundaries and sampling

Check quantity, unit, multiplier, sign convention, cumulative versus instantaneous values, sampling and aggregation. Conversions need a traceable basis.

Identically named measurements are not necessarily comparable: installation location, asset coverage and reporting window may differ.

Asset and measurement boundary

Record identifiers, coverage, connected assets and exclusions.

Time

Record timezone, device clock, collection time, process alignment and aggregation window.

Quality

Distinguish raw, corrected, estimated, missing, stale and unconfirmed values.

#Check periods and process delays before aligning records

Simultaneous arrival does not mean two readings describe the same physical process. Demand propagation, meter intervals and manual records may have different delays.

Define the time resolution needed for the decision before aligning records. If alignment is not possible, state what can still be compared and which records are needed.

#When records are missing, establish what can still be assessed

State what can still be assessed, what cannot, and the priority of missing inputs. Collect information that can change the present decision first.

This does not require every site to install an entirely new acquisition system. Existing information may be a starting point, within an explicit boundary.
