VTU designs and delivers turn-key plant simulation models for various applications.
Fuel Demand Models
Fuel Demand Models represent contracted performance guarantees. While the contract typically includes a limited number of guarantee points, the bonus-penalty calculations for plant efficiency shall be performed under every possible condition in the entire operating range of the power plant. This is accomplished through a physics-based simulation model that includes sub-models of all major plant components which in detail reflect the respective performance guarantees.Planning Models
Planning Models based on vendor guarantee data or measured ‘as built’ performance information enable the plant personnel to investigate the effect of various conditions and settings and to perform predictive studies based on scenarios of future operation.
Data Reconciliation Models
The process of data reconciliation uses a thermodynamic model of the plant and information on the quality of the individual plant sensors together with statistical analysis in order to create a set of heat balance data that comes closest to the measured raw data and at the same time complies with the balances of mass and energy. Plant operations and maintenance teams benefit from reliable data and unbiased indicators of measurement quality.
