SPPA-D3000 Operations Optimizer
Optimizing Power Plant Operation
Through Analysis of Archived Process Data
Optimize plant operation through an analysis of archived process data
Modern I&C systems archive the process data acquired during power plant operation. Further aspects of plant operation
are stored in other systems, e.g. maintenance systems and chemical laboratories. In other words, the operating
response of the entire plant is documented.
All the data necessary for an analysis of the response of each variable relative to thousands of other variables are
basically already available. Only the large number of data, their distribution among various archives, and the correlations
between them has hitherto prevented them from being used efficiently.
Now for the first time, SPPA D-3000 Operations Optimizer makes it possible to process and use previously neglected
knowledge from the various archives for the purposes of solving day-to-day tasks.
SPPA-D3000 Operations Optimizer - assess conditions accurately
Optimize processes and operating points
Simulate solution proposals
One of the primary applications of SPPA-D3000
Operations Optimizer is the extremely fast analysis
and display of correlations and interactions between
thousands of operating parameters.
Optimization targets are defined interactively at a
mouse click through selection of pertinent value
ranges. SPPA-D3000 Operations Optimizer provides
directly a display of the relevant influencing quantities
and the setpoints required to achieve optimization.
How will a plant, a unit or a process react to a parameter change?
Based on the measured data from the I&C archives, the
condition of the relevant object can be displayed
immediately for any selected parameter constellation.
The decision as to whether the proposed solution for
a given task should be implemented or rejected can
be made quickly and confidently.
Examples of typical optimization targets are
• to increase efficiency
• to minimize wear
• to minimize consumption
Assess operating regimes
The effects of a particular parameter constellation on the
whole plant or a specific subprocess can be assessed
quickly and easily with SPPA-D3000 Operations
Optimizer. It performs this function by evaluating the real
plant data from the I&C archive, i.e. without modelling.
Process parameters are set to achieve the target,
plant operation is optimized.
The most efficient operating regime for a given
situation can be implemented.
The red bars define the optimization target.
The green bars display the result, i.e. the
appropriate parameter settings.

SPPA-D3000 Operations Optimizer - analyse large data volumes quickly
Compare plants, units or processes
Differences in performance between
• whole plants
• identical units or
• processes running at different times
or with different parameter settings
are visualized within seconds through the high-speed
comparison of thousands of parameters. Anomalous
parameters are highlighted and listed according to the
magnitude of deviation.
Optimization potential in processes, in units or in the
whole plant is easy to identify. Suitable action can be
planned.
Number and distribution of archived data records for certain
parameter constellations are analyzed in a 3D diagram.
Facilitate troubleshooting
All measured quantities stored in the I&C archive which
could influence a specific task are located within
seconds by SPPA-D3000 Operations Optimizer.
Check quality of a maintenance
or overhaul procedure
This capability makes it possible to eliminate many of
the possible causes of an acute malfunction or abnormal
performance. At the same time, the user can feel
confident that no relevant factors have been overlooked.
Comparing all the measured data recorded before and
after maintenance or overhaul allows the success of the
procedure to be determined at the click of a button.
In many cases, the cause of a malfunction can be
determined more rapidly and with minimum analytical
effort.
Warranty claims can be made promptly for any
deficiencies or required corrective measures identified
before the warranty period has elapsed.

Which data can be processed?
As a general principle, all scalable quantities can be
analyzed by the SPPA-D3000 Operations Optimizer.
The data source and data format are irrelevant. It is
even possible to combine different data sources.
I&C archives are ideal sources, as are databases of
vibration and oil analysis information or archives from
waste water laboratories.
How are data imported?
Data are first extracted as an ASCII or csv file from the
selected database. Standardized extraction tools are
available for Siemens I&C. These allow variable names,
e.g. KKS, and the desired time frame to be specified. It
is possible to optimize this process by means of a batch
file so that SPPA-D3000 Operations Optimizer is
regularly supplied with up-to-date information. Files
generated in this way are used to create a database
image, a pdi file for SPPA-D3000 OPT, which contains
the correlations between individual items of data. Data
are analyzed by means of the SPPA-D3000 Operations
Optimizer Explorer.
Is the volume of data restricted?
In the current version, the data volume within one pdi
file is restricted to 10,000 variables and 20 million data
records. This artificially set limit can be extended if
required.
Are there any special requirements of the
computer?
Standard personal computers or notebooks operating
on the Windows 2000, Windows XP, SCO Unix or
Linux system can be used.
A computer for standard office applications is sufficient,
although high computing capacity would provide better
ease of use. For large numbers of variables, therefore,
it is advisable to use a faster computer with a highcapacity main memory.
