DYNAMIC SIMULATION OF ELECTRIC MACHINERY Chee-Mun Ong, published by Prentice-Hall, � 1997 Chee-Mun Ong The CD-ROM accompanying the book contains project files for the Macintosh, Unix, and Window operating systems. Files given here are for the Window operating systems. The folders are labelled in accordance with the chapter number of the text. For example, C2 refers to project files for Chapter 2. In general, filenames beginning with the letter M are MATLAB M-files and those beginning with the letter S are SIMULINK files. The MATLAB files will run on MATLAB 4.2 and the new MATLAB 5. SIMULINK files for version 1 and 2 are, however, slightly different. For convenience I have included the files for both SIMULINK 1 and 2. Those for SIMULINK 1 have a .m filename extension and those for SIMULINK 2 have a .mdl filename extension. For example, the MATLAB M-file for project No. 3, m3.m say, will typically be associated with s3.m for SIMULINK 1 and with s3.mdl for SIMULINK 2. To view or run a SIMULINK file, first move to the directory containing the SIMULINK file, then use the open file command under the SIMULINK menu to select and open the SIMULINK file. If there are parameters in a lookup table or a repeating-sequence block that are not initialized, there will be error/warning messages saying so at the time when the file is first open. Within most of the SIMULINK files, I have placed a masked block of the M file that you can use to initialize the simulation. Double-click on the masked M FILE block and respond to the prompts in the MATLAB command window to properly initialize the simulation with parameters and operating condition, and to run the simulation. The given files have been tested on MATLAB Version 4.2c and SIMULINK Version 1.0a and on the pre-release MATLAB Version 5 and SIMULINK Version 2. Also included in the CD-ROM are the following utility files: fftplot.m - for computing and plotting the fft of a variable. The variable value and time are stored in row arrays. sizeplot.m - for resizing the figure window These utility files should be placed in a directory that is on the MATLAB's search path, for example, in the MATLAB/bin directory. Depending on the display resolution used, the SIMULINK screen window on your computer monitor may or may not display the given SIMULINK simulations in full. The screen's view can be increased by setting the display resolution higher, at the expense of smaller lettering. The simulation diagrams given should fit within an open screen when using a display resolution of 800X600 pixels or higher. ****************************************************************************** CONTENTS CHAPTER 2 (C2 Folder) INTRODUCTION TO MATLAB/SIMULINK Exercise 1: Variable Frequency Oscillator SIMULINK file s1.mdl MATLAB m-file m1.m Exercise 2: Parallel RLC Circuit SIMULINK file s2.mdl MATLAB m-file m2.m MATLAB m-file m2init.m(1st half of m2.m) MATLAB m-file m2plot.m(2nd half of m2.m) Exercise 3: AC Energization of a RL Circuit SIMULINK file s3.mdl MATLAB m-file m3.m Exercise 4: Series RLC Resonant Circuit SIMULINK file s4.mdl MATLAB m-file m4.m ************** CHAPTER 3 (C3 Folder) BASICS ON MAGNETICS AND LINE MODELING Project 1: Line Parameters and Circuit Models: (a) Relative Accuracy of Circuit Models for Different Line Lengths (b) Real and Reactive Power Transfer SIMULINK file none MATLAB M-file m1.m Project 2: Switching Transients in Single-Phase Line SIMULINK file s2.mdl MATLAB M-file m2.m ************** CHAPTER 4 (C4 Folder) TRANSFORMERS Project 1: Short-circuit and RL Load Terminations SIMULINK file s1a.mdl (linear transformer) SIMULINK file s1b.mdl (piece-wise linear saturation) SIMULINK file s1c.mdl (lookup table saturation) MATLAB M-file m1.m MATLAB M-file fftplot.m (fftplot.m should be placed in a directory on MATLAB's search path) Project 2: Open-Circuit Termination, In-rush Current, and DC Bias Core Saturation SIMULINK file s1c.mdl (lookup table saturation) MATLAB M-file m1.m Use the given FFTPLOT.m to obtain the discrete Fourier transform.
