Energy Efficiency Investigation
ISC can help companies faced with increasing energy bills determine the
most efficient way of operating plant. This can involve redesign of control,
new equipment (e.g. switching from fixed speed pumps to variable speed pumps)
and changes in operation. Dynamic models can be used to accurately estimate
the energy savings, which is important to help justify any capital expenditure.
Calculations provided by vendors of equipment or energy saving bodies
often do not contain the detail necessary to produce an accurate assessment.
Our rigorous modelling approach provides confidence that the changes will
really deliver the benefits and make energy saving projects a success.
PumpSim - VSD Energy Efficiency Tool
The Water Industry has enormous potential for energy savings by
replacing ‘on-off’ pump drive controls with VSD technology. Unfortunately,
it is difficult to determine in advance whether a VSD investment will deliver
the required return on investment.
PumpSim has been developed by ISC to facilitate the associated decision-making process. It is a (PC-based)
MATLAB/Simulink add-on that gives clients an accurate
forecast of energy savings. Developed with water industry professionals, it
removes onerous mathematics from the user interface while enabling accurate
representation of pumping station behaviour through application-specific parameter
entry. Armed with the predicted energy savings, the client is better placed to
decide whether a VSD investment is justified.

Modelling Pumping Stations for Energy Saving Assessment
Example Projects:
- Water Pumping Energy Savings -
Dynamic models are used to accurately estimate potential energy savings
through changes to plant (e.g. variable speed drives) and
operating regimes (e.g. pump scheduling, level setpoints)
(Download project
presentation).
- Paper Mill VSD Energy Audit -
An audit on the use of VSDs to replace throttled valves
was undertaken for all large pump/motors at a paper mill.
This resulted in the development of template calculations for
application across the various mills operated by the client
company. (Download project
note)
- Aeration of Waste Water -
Models of waste water treatment plant (WWTP) have been
coupled to models of compressors to determine possible
energy savings through changes to control.
