Belsim engineering offers software and services for modeling, monitoring, and optimization of power generation plants, conventional as well as nuclear.
The two type of power generation plants are treated somehow differently at application level.
For the nuclear power plants the modeling does not cover the nuclear power source and the primary loop. The model is mainly focused on calculating the core thermal power with the highest confidence possible by integrating contributions from the modeling of the secondary and tertiary loops. Increased confidence in the core thermal power reconciled values allows the operator to uprate the electric power output of the plant, with important financial gains and reduced investment. The reconciliation will also help identify and (re)calibrate erroneous sensors and deliver soft sensors for parameters that are whether not measured or cannot be physically measured (e.g. core thermal power).
The only component modeled in such application is water in its cycle as transfer agent of the atomic energy released by the nuclear fuel to the steam turbine generator that transforms it into electrical power.
Belsim and its partners deliver also studies of performance monitoring and optimization for parallel steam turbine trains aiming at guiding the plant towards the most efficient utilization of its assets. As electricity power outputs of such plants is enormous, digit increases in efficiencies and/or power uprating are translated into millions of dollars per year benefits.
Modeling of conventional power plants covers also the modeling of boilers or gas turbines releasing the chemical energy from the fuel, besides the modeling of the water cycle. Monitoring extends thus also to the monitoring of the performance of these pieces of equipment. Monitored parameters include but are not limited to boiler efficiency, gas turbine generator efficiency, waste heat recovery efficiency, specific consumptions of fuel per kW power, combined cycle efficiency, etc.
Besides efficiency parameter monitoring, such applications deliver as well soft sensors that can be used for better tuning equipment operation (e.g. convection channel temperature for boilers, exhaust turbine temperature for gas turbines, emissions, efficiency and mechanical power consumption of compressor side of gas turbine generator, fouling of waste heat recovery exchangers, intermediate steam temperatures, steam turbine efficiencies and their variation with ambient conditions, etc. Owing to its internal database of thermodynamic properties and calculation methods, Belsim's Vali is able to handle various type of fuels for power generation boilers: natural gas, residual gas, fuel oil, coal, etc.
