4 Energy management
Energy and Power Management (EPMS) must be part of the Building Management
System (BMS) software. More specifically:
● Operational and engineering data from EPMS must be in the same database
as those of the BMS
● The following functions must use the same workflow, not requiring separate
training or additional login:
– Trending
– Custom Graphics generation
– Alarms management
– Logs
– User management with various authorization levels
– Scripting
– Help
4.1 Integration of meters
The EPMS must be capable to integrate any meter or breaker that has a known
Modbus registry map.
The EPMS must allow the bulk import (integration) of many devices as well as
import of individual devices.
The end user or engineer must be able to select for each meter or circuit breaker,
which data points should be polled, displayed, achieved. Searching/filtering of the
data point list must be available in order help the process above to be more
efficient.
For each data point there must be the option to have a high or low limit that will
create an alarm if exceeded.
The EPMS must allow the organization of integrated devices in Hierarchical
structure with areas and sectors where the devices belong.
4.2 Dashboards
The EMPS must have Dashboards that can show real-time data together with
processed historical data. For example, real-time power demand and daily energy
consumption of the last week on the same page.
Each device and each area are must have its own dashboard and premade
graphics showing basic characteristics and harmonics (if available from the
device).
4.3 Virtual devices and calculations
The engineer/user must be able to create virtual objects and assign to them
outputs of a calculation of existing datapoints. (For example, add power demand of
device A and device B, and assign the output on a virtual point to get the total
power demand of those devices.)
4.4 Libraries and templates
The EPMS must use libraries to allow the easy transfer of data from one project to
another. (For example, object models of custom-made meters or custom-
engineered graphics.
The EPMS must have premade object models and graphics for 7KT/7KM PAC
measuring devices and 3WL/VL/3VA circuit breakers as well as dedicated graphics
symbols for other commonly used electrical components such as batteries,
switches and UPSs.
