MODELS OF OPTIMUM AND ULTIMATE VALUES OF POWER SYSTEM PARAMETERS FOR ON-LINE OPERATION CONTROL

The aim of the work Is to Improve reliability and efficiency of power system operation for various scheme situations and regimes. Taking into account scheme changes and regimes for various electric power- stations of the system and other objects controlling operation conditions of the system models have been developed with the use of experimental design method. Relation- ships of reactive power and voltage on the output terminals will serve as generalized models for power plants, active and reactive power flows in the electric power linesfor electric network. For solution of this problem methods and algorithms for selection of optimum operation parameters of power plant and respective permissible conditions accounting for static stability requirements have been suggested. Examples of use of algorithms In the process of on~ lineautomatic dispatch control over electric power system have been presented.
