PSI Implements Gas Quality Tracking System at Swedegas

PSI has been chosen to implement a Gas Quality Tracking System for the Swedish transmission gas grid operator Swedegas. Stricter requirements for tracking gas quality and heat values in the gas transmission network had to be met. This was due to the unpredictable mixes of gas quality being fed in from the European gas network via Denmark as well as new in-feeds of biogas from plants in Sweden.

Data from the Gas Quality Tracking system, based on the PSIganesi gas network simulation system, is primarily used to calculate heat values and gas composition at the various exit points. These values are then forwarded to an existing system which executes the accounting process with Swedegas’ customers. Additional functionality of PSIganesi are line-pack calculation, leak detection, pig tracking and the calculation of the network’s future behaviour based on forecast data.
