Gas Contingency Analysis (GCA) Siemens PSS SINCAL Gas Modules

Gas Contingency Analysis (GCA) Requirements and Use Cases

In order to increase the reliability of the gas supply and transport as well as operational safety, it is useful to analyze the effects of malfunctions, contingencies and planned maintenance measures at individual elements or of entire element groups.

• Assessment of the flow conditions in case of malfunction (or maintenance) of individual network elements and generators or element groups as well as the caused malfunction of further elements due to the contingency
• Consideration of all possible malfunction combinations or specific analysis of the malfunction of elements groups
• Analysis of the operational safety and analysis of weak points in the network as well as the derivation of countermeasures to increase the security of supply and reliability

Solution

The module for the steady-state calculation for gas networks (GS) in the PSS®SINCAL Platform is the basic module and enables the modeling of a gas pipe network, the steady-state calculation and the appropriate options for evaluating the results.

• Comprehensive modeling of branch and node elements as well as characteristic curves for the behavior
• Calculation of the steady-state pressure, volume and flow distribution in any meshed networks
• Consumer modeling depending on the ambient temperature
• Automatic redistribution of supply depending on the selected limit values of the generators and calculation of the supply shares from different sources at network nodes as well as the flow time
• Hydraulic head diagrams for user-defined routes considering the geodetic height
