Dia-El'din A. Methods of estimating operational modes and diagnosis og electrical part equipment of thermal power plants.

The purpose of a thesis - to provide qualitatively new level of problem solving of the controlled conditions of thermal power plants at the exepense of development of principles and methods, structrually both algorithmic software of an estimation of mode of operations and state of inventory of an electrical part of thermal power plants and operating support of the solutions of staff. The researches were conducted with usage of the theory of relational databases, Fourier transform, frequency methods, numerical methods, knowledge base and algorithms of making diagnostics federated systems of a state of inventory and mode of operations of a electrical part of thermal power plants.The tools of making of consulting diagnostics model of an electrical inventory designed. The consulting model of diagnostics of the generator is created. The control conditions of methodology of an electrical part of thermal power plantsis perfected: Principles of build - up, structure, methods of making of mathematical models. The dynamic mock- up of an electrical part of thermal power plants designed.The mathematical model of the generator is perfected, which contains two differential equations and relations for regime parameters. The method of algebraic equations for solution of air-break system is designed. The software providing substantial improvement of the interaction of staff with IBM designed at the expense of operating shaping of models of problems, schemes for different mode of operations of thermal power plants. The results of operation can be utilised in electrical power industry for the controlled conditions of thermal power plants.
