Partial empirical models for thermo-economical control systems of power units

The energy diagnosis of power plants and combined heat-and-power plants (CHP) is a very important form from the point of view of rational management of primary energy as well as from the economical and ecological point of view. The control procedures can be based on measurements or on simulations with application of mathematical models. The Authors present methods of identification of partial empirical models of components of CHP steam cycle. These models can be useful for thermo-economical diagnosis purposes.
