A phenomena that causes most severe transients in three-phase induction motors
The dynamical behaviour of a 3-phase induction motor supplied through a distribution transformer and during starting period, subjected to a very short time supply disturbance from the primary side of the transformer, while ...
Performance analysis of solar cell arrays loaded with passive loads
The dynamic behaviour of the linear first-order passive circuit is of considerable importance to engineers. However, dynamic responses of these circuits when powered with solar cell arrays have not received much attention. ...
Modeling of the saturated leakage reactance of induction motors as a time varying parameter for transient computations
A procedure has been developed for incorporating the saturated leakage reactance of induction motors into starting transient performance evaluation. An empirical formula has been provided for simulating the envelope of the ...
Analytical solution of the transients in induction motors due to asymmetrical terminal fault
When supply to the induction motor is short circuited the energy stored in machine, causes the machine to behave as a generator. This can result in very large transient negative torque and large transient current, especially ...
Teaching transient behavior of electrical machines with personal computers
(Elsevier Ltd, 1997)
This paper discusses the use of personal computers in teaching the transient and steady-state behavior of electrical machines. It explains how computer simulations help students to get better understanding and gain in-depth ...
A modified froelich's type equation for accurate modeling of magnetising characteristic of magnetic cores
A model equation is presented for accurate representation of magnetising characteristic of magnetic cores. A simple procedure is presented for calculation of the coefficients of the model equation. It has shown that with ...
