Abstract:
The simulation of transport networks in civil engineering has become increasingly important for the planning and stable operation of modern infrastructure. Compressors are essential elements in gas transport networks; they create pressure necessary for driving gas towards the consumers. This paper presents mathematical modeling of gas compressors, taking into account their individually calibrated physical profiles. The approach is based on conversion of the measured profiles into an explicitly resolved form suitable for globally convergent solvers. In particular, a proper signature of derivatives for the element equation of a compressor is provided. The usability of the approach is demonstrated on a number of real-life network scenarios.
