Contents of a Performance Monitoring System
"I long to accomplish a great and noble task,
but
it is my chief duty to accomplish small tasks
as if they were great and noble."
-
Helen Keller
Considering
what to include in your Performance Monitoring System
When planning for a Performance Monitoring (PM) system,
the first item to identify is the objective of the system. For many systems, the objective turns into a
great and noble task, but it is the small tasks which must be accomplished first,
in a great and noble manner, in order to create a successful program.
The small tasks in this case, are choosing the contents
of the PM system.
What data is needed to accomplish your performance
monitoring objectives? Gross and Net Electrical Output, Fuel Flow
rates, Fuel Heating Values, to name the most obvious. But, if you are also looking at corrected
performance, there are many pressures and temperatures which will also be
needed for the PM system to perform its duties.
How will this data be
collected? Manually? Electronically? Consider the following:
·
If electronically,
will the system be able to read from your existing data sources?
·
Will there be
additional expenses related to interfaces between the performance monitoring
(PM) system and the data sources?
·
Note that data
sources may include:
Third party
historians such as OSI-PI Database; Central control systems (DCS); Prime mover
control systems (i.e. GE Mark VI); PLCs or other
remote systems; Utility/Revenue metering; Market pricing indices; Corporate
information systems; and more.
Once the data has been collected and entered into the PM
system, the results need to be saved and archived for long term use.
Where will results from the performance analysis
be saved?
·
Will you need
additional hardware, software or licensing to add all the results to the
archive?
·
Will the archive be
online (extra hard drives, either internal or external), or offline (i.e.
tapes)?
·
Will the results be
available to everyone who needs access to them, when they need them?
Additional items to consider when choosing a PM system
include:
Trending: Do you need to include trending
capability in the system?
·
How easy is it for
the user to add additional or custom trends?
·
Will you be able to
trend raw data next to calculated data?
·
Where are the
trends built?
·
Can they be saved
for viewing with any time-set of data?
·
Can they be used to
view live data, including both raw and calculated values?
Reports: Do you need any pre-built reports included in the system?
·
How are reports
formatted?
·
Is there a set of
standard reports included?
·
Can the user setup
custom reports as needed?
·
Is there an option
to schedule the reports to be created automatically?
·
Is there an option
to create them manually?
·
Can reports be sent
to an email distribution list or a network printer?
Special Requirements:
Are there any special requirements
for your system? Is the selected
hardware and software sufficient to cover these additional needs?
These are only some of the items that need to be
considered when designing a performance monitoring system.

LM6000 Performance
Seminar to be held
in San Diego –
April 3 & 4
Learn about the thermodynamic relationships
behind Gas Turbine performance, and how to apply this to your units and
your site.
Delve into the economics and
application of correction curves - including an understanding of Throttle
Push.
Get an overview of ASME
PTC-22, the standard on gas turbine performance testing.
Learn about performance monitoring
programs for gas turbines, what you need to look out for, and what to do if
you think you may have a problem.
Walk away with information
and ideas that you can apply to your operation immediately.
April
3 & 4, 2008 at the Town & Country Resort in San Diego, CA; scheduled to
be convenient for attendees at the 2008 WTUI Conference (www.wtui.com).
No, it’s not too late, but space is limited. Call Now to Reserve your Seat!

T2E3 Provides Services
for Power Generators
Including the
following:
Analysis Tools & Software – from customized spreadsheets to add-ins for Excel or
complete compiled programs, T2E3 can develop software tools and analyses to
support all your performance monitoring needs, including integrating your
existing tools with available site data systems, to create online systems
providing data and results in real-time.
Training – both public seminars and customized options are available. Highly interactive sessions increase
attendees’ knowledge and understanding of the thermodynamic cycles,
instrumentation and analyses needed to improve equipment performance and
reliability.
Performance Test Support – if your site is
required to perform annual capacity or power purchase performance tests, having
Tina Toburen from T2E3 on site to direct the testing can lead to a smoother
test execution with more consistent performance results. Professional reports can also be produced to
communicate the results to all required parties.
Site Marketing and Dispatch Support – Do your marketers and/or
dispatchers understand the operation of your facility? Do they constantly dispatch the plant at
loads which are difficult or impossible to maintain? T2E3 can help you build tools and training
programs to help all parties understand the expected changes in performance due
to ambient conditions and operating constraints. These tools can also lead to a greater
understanding of the long-term economic outlook for your facility.
Unlock the potential of your
operation. Call for more information on
how we can work together, today!
