Educational goal:

Acquisition of knowledge in the field of modelling of stationary and non-stationary condition and occurrences of synchronous, asynchronous and direct current machines.

Educational outcome:

The ability to develop a mathematical model of the synchronous machine suitable for computer aided analysis- the ability to study the stationary condition and non-stationary occurrances of the synchronous machine- the ability to develop a mathematical model for the asynchronous machine suitable for the computer aided analysis- the ability to study the stationary condition and non-stationary occurrances of the asynchronous machine- the ability to develop a mathematical model for the direct current machine suitable for computer analysis- the ability to study the stationary condition and non-stationary occurrances of direct current machines.

Course content:

Introduction. The basic mathematical model for the electrical machines. Parameters for electrical machines. Transformations of the original mathematical model for machines (C,F,H,G,D,B,E and T). Electrical machine types. Park’s equations. Operation inductions (reaction) and the time constant of the synchronous machine. Stationary and quasi-stationary condition of the synchronous machine. Stationary condition of the asynchronous machine- the equivalent scheme. Simulation of the asynchronous machine supply. Models of asynchronous machines for method of field orientation control; electricity and voltage supply; rotor flux orientation; the analogy with the direct current machine. The model of the synchronous machine for field orientation control. Simulation of non-stationary processes in direct current machines. Non-stationary processes in synchronous machines. The synchronous machine model. A three-phase short circuit of the synchronous generator. The asynchronous operation of the synchronous machine. The non-stationary condition of the asynchronous machine. The physical explanation of the motor starting process. The analysis of the asynchronous machine starting in real environment.

Teaching methods:

Classes are carried out either as lectures or as exercise classes. The lectures use modern illustrations for the intuitive understanding of the subject matter. For the full understanding of the subject matter, the auditory exercises supply examples that accompany the lectures and encourage the students to independently solve engineering problems. A part of the exercise work is carried out in the computer laboratory.
