SimNet SSGas

SimNet SSGas is a software package for steady state simulation of gas networks. Depending on the version it allows for simulation of the gas network of low, medium, high medium, high pressure, and multi-pressure networks, where there are several levels of pressure at the same time.

Computational properties:

The calculated network may have any number of sources with different pressures and flow rates, and any number of other nonlinear elements: compressor station (compressor), city gate station (pressure regulator) and the valve. These elements may work with a setpoint value of one of the following parameters: inlet pressure, the outlet pressure, the compression ratio (pressure reduction ratio), pressure drop (pressure increase), flow. In addition, the network may inlude any number of valves, which are operating in the open / closed states.

The results of the simulation are: gas pressure, temperature, and heat of combustion in the nodes, flow. decrease in the power, and the average values of: the flow velocity, the Reynolds number, friction factor, compressibility factor in the pipes, the missing values of parameters describing non-linear elements, pipeline linepack (accumulation of gas) in the network.
A calculation engine of the software package has an efficient algorithm, allowing for definition of the parameters of the gas, including: varying the height of the nodes, heat exchange with the environment, the Joule-Thomson effect , gas composition changes as a result of mixing of the gas streams. The program has its own module which allows to calculate the actual gas consumption in the network.

Applications

The package allows to perform the following tasks:

  • examine the behavior of the network under certain conditions,
  • determination of passages in which the network is overloaded (bottlenecks) and in which there is a reserve capacity,
  • planning the modernization and expansion of the network,
  • issuing assurances of gas supply for future customers,
  • checking the operability of the network during repairs of selected or excluded part due to failure of the network,
  • assessment of the quality of work of telemetric system and measuring devices,
  • determination of the necessary number of measuring devices and their location (measurements in other parts of the system can be replaced by the results of simulation),
  • calculate the distribution of energy flows in the system (gas quality tracking to determine the actual calorific value at any point in the network) (Example of simulation results of gas quality tracking in the pdf document).
