Bereznytskyi D. Diagnosing of auxiliary transformer and systems for technological protection in the power-generating units of heat power electric station

The object of study is the processes taking place in a mains transformer of needs and in the process turbine protect the and is displayed in the automated process control system. The subject of study is means the diagnosis of mains transformer of needs and technological protection of the turbine. In the dissertation for the solution and analysis of the tasks the following methods are used; methods of technical diagnosis for a approach for determining the technical condition of equipment, theory of finite automata for synthesis of structures devices, diagnostics, theory of probability for finding errors developed devices, the analytical capabilities of computer algebra for calculation of mathematical models. Mathematical model to assess the residual life of dry power transformer needs, working conditions, improved mathematical model for building a resource of dry power transformer needs are developed; First time developed a mathematical model for diagnosis of technological protection reduce vacuum turbine; received further development of the method of synthesis of structural schemes for the diagnosis of electrical equipment based on the mathematical apparatus sekventsiy. Synthesized structural scheme of the device for the diagnosis of dry power transformer needs with regard to work conditions; synthesized structure of the device for the diagnosis of protection reduce turbine power vacuum thermal power; developed algorithms and functional circuit microprocessor means of diagnosing and managing auxiliary electrical heating power. Degree of implementation, within the industry. Field of use - agencies and companies involved in construction, maintenance and repair support, and managing electrical thermal power stations.
