Sarafannikova N. Optimization of big energy system management in critical modes of operation.

The object - the automated systems of dispatching management of the big electroenergy system; the purpose - increase of efficiency of functioning of the big electroenergy system; the methods - complex use of the mathematical apparatus of statistics and the theory of accidental processes, theories of fractals, regressive analysis, numerical methods, MathCAD, theories of signaling; innovation - for the first time is constructed continuous model for realization of rapid prognosis of critical situation and exposure of coordinates of knot of the system the origin of catastrophe is possible in which; the criterion of definition of time for stabilization of a critical condition of system is offered; results - the problem of optimum control of a power supply system in a critical mode of functioning has received the further development; application - was launched in the university educative process and it is used by development information-operating systems electropower objects in Institute of electrodynamicsof NAS of Ukraine; area - automated management.
