Abstract The saturation of the magnetization curve have a great influence on the transient response of the voltage regution of application or removal of load the loop chosen for investigation in part (A) consists of ad.c. generator driven by an induction motor , and aspecial amplidyne aquiped with two control field windings to operate without a refernce voltage. The transient response is calculated, for sudden application of removal of load, using the Time Series Numerical; Method, that was early developed by Prot. A. Tustin and that was then modified by Dr. G.L.d’Ombrain and Dr. A. Rashwan. The results obtained are checked analytically using Laplace Transforms and exprimentally from the actual system in our laboratory, also by sdimulating the investigated system on an analogue computer. Chapter (1) gives the types of non-linearities, the various methods of investigation of nonlinear systems, and the didderence between the results obtained using each method. In Chapter (2) the investigated system and the practical methods used for evaluating the parameters of each element. |
