The invention is directed toward an electrical power control system () in an electrical power system, having: a power control unit () for setting electric state variables and/or parameters in a current conductor, to be controlled, of the electrical power system, having: means () for detecting electric characteristic values () of the current conductor; a function processor for applying a control function (F()) from a mathematical set of control functions to the electric characteristic values, and for determining controlled variables (y) for achieving the parameters; and coordination means for determining a control function (F(u)) from the set of control functions with the aid of operating states of the electrical power system. This system renders it possible to achieve a predictive tuned control of the electrical power control system which can also stabilize unusual operating states of the electrical power system.

Electrical power control system, and method for setting electric state variables and/or parameters in a current conductor

The method according to the invention is based on a configuration model of a part of an electrical power distribution network, describing a totality of possible configurations of appliances. The configuration model is used to systematically produce () all the possible configurations which satisfy a predetermined set of functional requirements, in which case each possible configuration may have at least one associated characteristic value, and a solution configuration is defined which optimizes this characteristic value. It is thus possible to produce an optimum configuration automatically, without any need for expert knowledge about the appliances used in the configuration. In one preferred embodiment of the invention, a simulation model for simulation of a technical response of the solution configuration is produced automatically (). It is thus possible to test one or more solution configurations by simulations (), without any need for expert knowledge about the characteristics and simulation models of the appliances used in the solution configuration.
