Levkonyuk A. Monitoring of controlled power transmission corridors loading acceptability.

The оbject of research: processes in electrical power systems. The purpose of research: increase operational reliability of determining transmission corridors loading acceptability of ES-based models aimed at using the results of synchronized measurements of voltage vectors at individual facilities ES, and the creation of effective tools for constructing such models Methods of research: methods of mathematical modeling of steady-state ES regimes, methods of analysis of ES static stability, the inductive method of self-organizing models of complex systems, the method of least squares, artificial neural networks, technologies and tools for creating high-level software. Theoretical and practical results and innovations: A software package for automated assembly and testing the PM of any controlled sections of EN was developed; a software interface for automated sampling in form of a script for the software DIgSILENT PowerFactory was developed,which realizes EN static stability calculations. The necessary conditions and recommendations for practical use of the developed instruments and PM were investigated. For the first time using the inductive method of self-organizing models of complex systems models are built to determine transmission corridors loading acceptability of ES. For the first time the possibility to create duplicate models that differ slightly from the best models of optimal complexity as to the composition of the elements of the input vector of variables and values of the criterion of regularity, but can be used as a backup in case the "loss" of the input to this best model. For the first time it was experimentally proved that generated models in the aspect of a reliable classification of transmission corridors loading acceptability of ES are not inferior to the ANN. For the first time to improve the reliability of the detection of changes in the structure of the transmission cooridors of the ES a two-step method using a specially constructed with the help of GMDH models was proposed. Subject and degree of introduction: are used by system operator NPC "UKRENERGO". Effectiveness of implantation: The results obtained in the thesis were used in the preparation of regulatory document "Sustainability of energy systems. Guidelines ",developed software modeling complex to determine the transmission corridors loading acceptability of Ukrainian ES in the real-time using the results of synchronized measurements of voltage vectors at predetermined monitored objects embedded in the NPC "UKRENERGO". Sphere of use: electric power facilities and systems.
