PowerMonitor4Feed
PowerMonitor4Feed is a complete power monitoring and costing
system. It allows you to monitor, analyse and report on all
your site's power including electricity, steam, gas and
oil. PowerMonitor4Feed logs what you have used and when.
It allows you to compare different products' requirements and
costs. Historical trends let you look at total power as well
as power in different areas. Power can be related to
different products and production run length.
Equipment
PowerMonitor4Feed runs on a standard PC running Windows 7
Pro. It continually monitors power via a variety of sensors
such as current transformers, power meters and flow
meters. PowerMonitor4Feed is flexible and can obtain readings
from a variety of areas depending on the plant layout. The PC
is powered via an uninterruptible power supply (UPS) to ensure data
recording integrity. Current transformers (CTs) are normally
fitted on one phase of major panels such as grinders, pellet
presses and major distribution panels. Split core CTs enable
them to be fitted without disconnecting any cables. Boilers may be
monitored by installing water meters and/or gas/oil
meters. When PowerMonitor4Feed is installed on site with DSL's
AutoPilot4Feed control system, existing sensors may already be
available. Electricity meters which give half hourly totals
are not suitable as PowerMonitor4Feed monitors readings every few
seconds to enable it to allocate power to different products.
High Starting Currents
When starting very large star delta motors, meter readings
sometimes go off scale whilst in star. PowerMonitor4Feed may
be configured to assume a high set current should the reading go
off-scale, i.e. in a start situation.
Calibrate Readings
All inputs may be calibrated to give accurate values. In
addition, where some areas such as offices, services, routing etc
are not directly monitored, an estimate of power usage may be
assumed.
Networks
Since PowerMonitor4Feed runs on a standard PC running Microsoft
Windows, any standard Windows feature may be used. This
includes networking to other PCs, printing, remote access and so
on.
Open Database
All PowerMonitor4Feed's data is normally held
in a SQL Server database. The database
may be backed up or copied to a writeable CD or memory stick as a
backup. Thus, in the event of a failure of the
PC, a new PC may be set up and the data restored from CD,
minimising any loss of data.
Real Time Monitoring
The real-time display may be configured to display current
values together with totals and a trend showing values for the past
hour.
Logging
PowerMonitor4Feed logging may be
split into two main areas:-
* Per product - shows product energy
consumption
* Per area - shows consumption totals and
comparisons
All data is logged for a minimum of three years on-line
and earlier years may be archived to writeable CD or memory
stick.
Alarms
PowerMonitor4Feed can set an alarm if the power in any
area reaches a pre-set value or if the cost of the electricity
exceeds a certain value. When electricity costs
vary significantly this is a useful warning when production may not
be economic.
Energy Consumption by Product
PowerMonitor4Feed makes it easy to see the energy
consumption and cost on a product-by-product
basis. Since this is stored on a per tonne basis
it is more relevant for pricing purposes. You
can produce a report showing all products together with the last
run details for a quick comparison.
When looking at historical trends, you can plot all values
for a particular product between any two
dates/times. In fact you can make comparisons
between two or more products, allowing you to see the effect of
changes to the plant, seasons, run lengths
etc. When viewing a trend of power
usage per product, clicking on a reading of the graph gives you
detailed information about that particular run.
Export to Excel
When viewing any data, even a graph, you can click on
'File', 'Copy'. If you go into Microsoft Excel
and click on 'Paste', the raw data is loaded directly into a
spreadsheet. If you need to do any further
comparisons you then have all the features of the spreadsheet for
producing additional totals, graphs, pie charts and so
on.
Electricity Costing
You can enter the cost of electricity in half hour
increments for this week and next week. At the
end of every week, next week's costs are copied to this week
allowing you complete flexibility throughout the year.
Improve Pelleting Efficiency
By plotting graphs of pelleting efficiency (kWh/t) over
time, operators can see the effects of changes to steam, throughput
and different ingredients. It also gives you
justification for product costing and allows you to see the effects
of run length.
Analyse Power Usage
PowerMonitor4Feed lets you do a host of comparisons and
investigations such as
:-
*
Investigate why one product takes more energy.
*
Compare electricity usage with your last bill.
*
Cost each product's electricity requirements - for meal and
pelleted products.
*
Display boiler conversion trends over a year.
*
Copy power figures to a spreadsheet to compare actual values
with targets.
*
Compare energy values before and after plant modifications or
different production methods.
Fully Configurable
PowerMonitor4Feed is fully user
configurable. This means that it can be modified
and expanded when required. New CTs and meters
may be added even while the system is
running. PowerMonitor4Feed may be
supplied in English or at extra cost, a variety of
languages.
Support
PowerMonitor4Feed can be supplied with a modem / internet
connection and remote access software for remote support
or modifications.
