Evaluation of the operating state of asynchronous motors of the Dukovany nuclear power plant by the method of frequency analysis of stator current
Štěpanovský, Libor ; Kasárník, Milan (referee) ; Mastný, Petr (advisor)
The masters thesis is concerned with the setting of limits and criteria, the design of database environment and the evaluation of the current state of motors of the important machines related to own consumption of the Nuclear power plant Dukovany. The first part of the thesis is a short description of induction motors, the evaluation method and the inventory of the observed motors related to own consumption of Nuclear power plant Dukovany. The second part of the thesis concerns the design of limits and criteria for evaluating the current state of these important motors. Finally, the thesis shows a short description of the electro monitoring system together with the description of the database environment created. In the supplementary materials of the thesis, there is a design of a protocol template for evaluation of the current state of the motor and a technical report template for regular evaluation in monitored areas MCSA (Motor Current Signature Analysis) of the state of the induction motors.
Single-Phase Induction Motor
Vácha, Pavel ; Lapčík, Josef (referee) ; Hájek, Vítězslav (advisor)
The bachelor work is concerned the thesis of a single-phase induction motor that´s perpetually more used in all over the world. Its aim is assembling the information about this type of motor and its calculation. The content of the first part is the theoretical analysis of a single-phase induction motor and acquirement ways of the stroke moment. The practical part contains a basic schema calculation of the single-phase induction motor with an auxiliary phase and a processing demonstrate example of calculation of the single-phase induction motor with concrete parameters along suggested process. In the conclusion there is the evaluation of the whole process.
Single-Phase Induction Motor Calculation
Vácha, Pavel ; Vítek, Ondřej (referee) ; Hájek, Vítězslav (advisor)
The master´s thesis deal with the thesis of a single-phase induction motor that is more and more used all over the world. Its aim is assembling the information about this type of motor and its calculation. The content of the first part is the theoretical analysis of a single-phase induction motor and acquirement ways of the stroke moment. Than the work contains a project of basic schema of the single-phase induction motor with an auxiliary phase. The practical part is devoted to an elaboration of demonstration example of the single-phase induction motor with concrete parameters calculation, its method was projected before. Than there is practising successived measuring on the motor of the same parameters made firm EMP s.r.o. Slavkov by Brno in this part. In the conclusion there is the evaluation of the whole process with reached results.
Parameter analysis of induction motor equivalent circuits
Minks, Ondřej ; Běloušek, Radim (referee) ; Mach, Martin (advisor)
This work deals with the determination of the parameters of induction motor equivalent circuits in T-network, gamma-network and inverted gamma-network form from no-load test and discovering voltage dependence of these parameters. For each of these circuits are determined dependencies of the torque and the stator current on the slip. Using the MATLAB simulations, the theoretically derived dependencies are compared with real, which are measured on the motor with the squirrel-cage rotor with power 0,6 kW, 2p = 2, both in operating and in whole motor area.
