FlowTran SIROGAS
Tracking Prediction Checking Modelling Leak Detection
SIROGAS
SIROGAS is the hidden simulation engine that executes the input file
written by FlowTran. SIROGAS is written in Fortran hence it can be implemented
on any computer for which a FORTRAN 77, 90 or 95 compiler is available.
FlowTran is written in Microsoft Visual Basic and can only be run in a MS
Windows Environment. However the input file written by FlowTran is a text file
and the output files produced by SIROGAS are all text files. Hence FlowTran on
a PC can control and display output from SIROGAS running on another computer
connected via a network.
SIROGAS is supplied as an exe and as MS Windows DLLs so that simulations
can be directly linked into other calculations such as design optimisation,
base case variations etc. Excel, VB and VC++ projects are supplied as both
examples and templates of the use of the dll.s

Tracking
What you need
- FlowTran to develop the configuration
file that describes your network and the output you require, to display a
map of your network, and to display SIROGAS results;
- A means of moving your measured
pressures, flows etc. on to a PC. This can by a file, by writing code in
Visual Basic or VBA, Fortran, Borland Delphi or Borland or MS C++;
- You may also wish to move SIROGAS results
to your SCADA data base.
The simplest procedure is to use Excel macros as all the standard Excel
timing, graphical and other procedures are available and use can be made of the
Excel macro written by SIROGAS to display all requested data. FlowTran includes
several demonstration and template Excel workbooks, Visual Basic and C++
programs calling the DLL.
These can be set up by your own staff or we can do it for you. Staff
Training is included in FlowTran Maintenance

Prediction
It is always nice to know a crisis is imminent before it actually
arrives. This is the big advantage of having a prediction model.
What you need
- FlowTran to develop the configuration
file that describes your network and the output you require, to display a
map of your network, and to display SIROGAS results;
- Either a restart file from an earlier
simulation; usually the FlowTran Tracking Model;
- Or measured data for the past several
hours of operation;
- Expected supply and demand conditions for
the period to be predicted. This data can be pasted into FlowTran using
the Windows Clipboard. If you wish to automate this transfer of data, the
simplest procedure is to use Excel macros as all the standard Excel
timing, graphical and other procedures are available and use can be made
of the Excel macro written by SIROGAS to display all requested data.
FlowTran includes demonstration and template Excel workbooks of linked
Tracking and Prediction.
This can be set up by your own staff or we can do it for you. Staff Training
is included in FlowTran Maintenance

Generating
First the desired scenario is created in a standard SIROGAS simulation in
which all the quantities measured by the SCADA are output to a standard SIROGAS
output table. The program PsuedoScada.exe supplied with FlowTran is run to read
this table and supply the measurements at Scada time intervals. Various types
of error can be added to simulate measurement errors of various types. Time
compression is also available. Three measurement data formats are available and
more can be added as the complete VB project of PsuedoScada is supplied.

Checking
SIROGAS includes a device that will force the pressure at a measurement
site to be equal to the measurements, and determine the flow necessary to
maintain the pressure. If all measurements were perfect then this would be zero
unless a leak was present in the pipeline. Thus consistency of measurements may
be checked by examination of these flows. Similarly if demand points are
simulated as know variable pressures, then SIROGAS calculates the flow which
can be used to check measured flow.

Modelling
Why you might want to simulate pipeline networks
- test out the steady state or transient
behaviour of a proposed network;
- examine the effect of compressor station
changes or additions;
- look at the effect of changes in gas
composition;
- see if additional short term demands can
be met;
- check that proposed additions to your
network meet requirements;
- examine the effects of compressor
failure;
- find survival times after a pipe failure.
- We can do all these as part of our
consulting service, or we can train your staff to do it.

Leak Detection
Leak detection in long distance gas pipelines is a controversial
subject. It will only work if you have accurate and well maintained
instrumentation. But if you do then SIROGAS can determine
- Mass of gas lost to date
- Current Leak size
- Leak location
- Time at which leak began
To set this up you
- set up a FlowTran model of your network
which also creates a map of the network,
- define at least one leak detection zone
by clicking on all pipes in the zone on the map of the network,
- define the measurements (flow, pressure,
temp etc) by clicking on their locations,
- enter measurement accuracies,
- supply the measurements in the suggested
format,
- and start leak detection.
