= SOLVO™ = Solvo™ – is a modular tool for simulating heat balances of power plants. The software enables modelling of variety of power plant devices and processes: different kinds of steam and gas turbines, any kind of boilers, combined cycles plants and in addition paper, pulp and gasification processes. The software is targeted for predesigning new power plants, making revisions to old plants and act as calculation engine in power plant's on-line energy information systems. It can also be used in various case studies where solution of heat balances is necessary. Solvo™ is developed by Fortum and it has been in use from early 1990's.

= Overview = Solvo™ – is a simulation software for predicting process values and thermal performance of various power plant components. Solvo™ is modular thus the process is constructed of modules, which represent individual power plant components. The software contains wide variety of modules needed in modelling the performance of a turbine, boiler and gasification plant.

The calculations are based on the simultaneous solution of both mass and energy balances and specific equations describing the behaviour of a component. The basic idea of the software is that the physical properties of the components are defined by solving a reference state, after which the model can be used to simulate the behaviour of a component in a state different from the reference state. In other words, in the reference state the model defines the parameters of the components that can be used to simulate the behaviour of a component in a changed state.

Solvo™ runs under Microsoft Windows environment (versions 7,8 and 10). The calculation part and the graphical user interface (GUI) are combined as tight simulation package. Setting up a problem is carried out through the GUI by selecting components (e.g. pipes, pumps, heat-exchangers) from a library, connecting them with various lines types and giving initial values via specification sheets. After simulation the results can be presented on the same flow sheet, different diagrams can be shown and/or data can be transferred to Excel for post processing. Solvo™-Excel interface can transfer data in both directions enabling to create tailored reports and to perform several simulations automatically.

Solvo™ can be used to simulate processes from individual devices to models containing several power plants, district heating networks and process heat deliveries. The maximum number of components in one model is 2600. Simulation is steady state.

= History = = SOLVO™ family = Solvo™ family includes the following applications. 1. Solvo™ Offline. Comprehensive analysis tool for power plant processes including enhanced graphical user interface and Solvo™-Excel -link. Targeted for engineering companies, power plants and educational institutes.

2. Solvo™ Optimum. Ready model of user defined process that can be operated using simple Excel based interface offering economic studies and sensitivity analysis of different operating modes, control values, fuel/electricity prices. Targeted for operators, shift leaders, process engineers and operation managers.

3. Solvo™ On-line. Integrated to power plant's information system to calculate current performance of the whole plant and individual devices. Optionally can also estimate target performance values and deviations between them and real performance values. Targeted for any kind of power plants.

= Localisation = Currently the main interface of Solvo™ is in English. However, help files are available also in Finnish and Russian languages. = External links = Solvo™ homepage
