Model Libraries

Provides a framework for simulation and analysis of electric power systems, both steady state and transient operation. The user can model the complete power plant from the energy source (oil, gas, hydropower or another renewable source such as wind) all the way through generator and power grid to the end consumer.

Is used for combustion engine system modeling, simulation and analysis, including the complete gas exchange. It is well suited to represent transient engine response and related engine control. Applications include control design with the purpose of reducing emission transients from the engine, transient exhaust condition modeling for optimum EATS operation conditions, and engine response dynamics. The Engine Dynamics Library utilizes a mean value combustion model for torque, charge flow and exhaust condition modeling.

Provides a framework for modeling and simulation of hydropower plant operation. It enables performance analysis and optimization of the operation of hydropower plants, for example, power plants with multiple reservoirs and multiple turbines in order to maximize the overall efficiency.
The library is suitable for simulation of transient operation such as load rejection to verify that the control system can handle these situations. It can also be used for studying control strategies to cope with the rapid load changes that become more frequent as other renewable, less controllable, sources of energy are increasingly used. Planning of commissioning tests and procedures can be set-up, thereby reducing the risk of unexpected events and minimizing costly tests done on the actual plant.

Provides a framework for modeling of thermal power plant operation including transient operation. Different plant designs and their respective dynamic behavior can be studied already in the concept design phase.  A particular advantage is the ability to simulate dynamic as well as steady-state behavior using the same model. In addition to covering the entire steam cycle, it can be used for the flue gas side and combustion models.

Is targeted at liquid cooling system design with compressible or incompressible flow. Applications include engine cooling, battery thermal management, and cooling of power electronics and machines in automotive, industrial equipment and process industries.

The AirConditioning library is a full-featured model library for refrigeration and A/C cycles with typical working media such as R134a and even CO2. It contains advanced two-phase flow and air handling models for all design phases from conceptual design to control implementation.
