Research goals: Achievement of several aims is expected from this project: Development of procedures and softwares for determining optimal regimes of electric power system functioning. Further development and improvement of existing softwares in load-frequency regulation and digital voltage/VAR control in electric power system with practical implementation. Development of algorithms and methods for making electric power system simulation models and their using as a training simulators in students and operaters education at dispatching centers. Obtaining exact computation procedure of process information relaxation times in remote control centers and dispatcher centers in modern technical control systems and also real defining of operating staff dynamic loading with process information in every power system control center. Development of algorithms for synchronous generator protection in power plants during asynchronous states and finding more reliable method in state variable analysis from which is determining of asynchronous state much simplier. Obtaining of computation models in electric locomotive representation with special attention in studying connection between 2x25 kV network and transmission electric power system. Development of digital simulation models for subsynchronous resonance analysis as well as torsional oscillation on agregates in large power plants and procedure determining for experimental checking. Software development for real time identification of transient states in hydro units.
