Presentation - Task 5 - Final Stakeholder Meeting

Report
EUP Lot 30 Task 5
Definition of Base Case
Prof de Almeida (for Hugh Falkner
Feb 2014, Brussels)
Date (if applicable)
Presentation Title
Objectives of Task 5
• Selection of the base cases
• Assessment of the environmental impacts, at both product
and EU level
• Assessment of LCC, both at product and EU level
Date (if applicable)
Presentation Title
Base case selection
• A total of 22 base cases have been selected to ensure that
the key characteristics of each group of products are
adequately captured.
• If differences between base cases are found to be
negligible, then it is possible that at a later stage some base
cases might be merged.
• The base case models are based closely on real products,
but care must be taken in interpretation of the whole stock
results

Base case 18 – 22 Motors + VSDs
The energy consumption is calculated from the sum of the VSD +
motor losses, with an additional 20% increase in motor losses to
take account of the impact on motor losses of the VSD.

• The selection of 25, 20, 75 and 100% load points is in line
with published motor data. However, for the purposes of
this study, note that these load points are best considered
as the mid-point of a load range, ie87.5% - 112.% etc, not
everything between the load point and next lowest load
point (which would have been 75% – 100% etc).

• The material content and costs are based on that for
conventional induction motors. This is small source of
inaccuracy due to the different dimensional constraints,

Breakdown of energy losses, by product
Date (if applicable)
Presentation Title
Environmental analysis of base cases
• Soft starters
•
only very short running hours, due to the fact that these are incurred only during start /
stop instances.
•
Their energy use is extremely small.
•
Technically there is negligible scope for reducing losses, with the possible exception
of standby losses, on which there is little data.
There is little scope for measures to reduce the energy losses of soft starters,
except for standby losses.
Date (if applicable)
Presentation Title
Environmental analysis of base cases
• Induction motors
•
Small induction motors have relatively high energy losses due to their
proportionately high (kW loss/ kW rated) energy losses. However, the economic
potential for energy saving is limited by their low running hours.
•
Medium induction motors have already been regulated, and so despite their large
losses, the scope for further improvement is limited because of the higher (IE2 or IE3)
efficiency levels already assumed for the basecase.
•
Large induction motors use less energy than the small and large segments, but the
cost effectiveness of energy savings will be determined by later analysis.
Date (if applicable)
Presentation Title
Environmental analysis of base cases
• Induction motors continued
•
The Small induction motor segment appears to have a good energy saving potential.
•
Later analysis will show whether it is technically and economically justifiable to
introduce measures to promote medium sized motors at efficiency levels beyond
those already included in the” Lot11” regulations.
•
Similarly it is not yet clear what energy saving potential there is in the Large induction
motor segment.
Date (if applicable)
Presentation Title
Environmental analysis of base cases
• Variable speed drives
•
Small internal losses means that the total losses are only a very small proportion of
the total motor energy use.
•
Only on those below 10kVA is there any room for energy saving, and this may relate
more to power management and ancillaries rather than losses in the power converter
itself.
VSDs are efficient devices with proportionately little energy losses. Later analysis
will show the technical and economic potential for energy savings.
Date (if applicable)
Presentation Title
Environmental analysis of base cases
• Multistage submersible borehole pump motors
•
The low energy use and modest energy saving potential mean that Multistage
submersible borehole pump motors are a lower priority for regulation, but it may still
be practical to regulate them as part of an “Extended Product Approach” for Multistage
submersible borehole pumps.
• Combine motor + VSD
•
This base case has been introduced in order that other new technologies requiring a
controller for operation can be compared on a like for like basis. The base case of this
combination of parts becomes relevant in the context of tasks 6 & 7
Date (if applicable)
Presentation Title
Results
• For motors and VSD the use phase dominates, then comes
the production phase.
• For small soft starters the production phase dominates.
• For medium and large soft starters the use and production
phases are relatively evenly split.
• Distribution phase’s main contribution comes through
particulate matter
• End of life phase is predominately hazardous waste and
particulate matter
