Virtual lab of three-phase electric power experiments
Abstract
The paper presents the application of theory of electric theory and modeling methods to develop algorithms flowchart and build graphic user interface designs on computers. The program aims to simulate virtual experiments of three phase electric power theory without having to use pratical devices. Typical applications of the program are to simulate symmetriccal and asymmetrical three-phase circuit experiments for analyzing the relationship among the phase and the magnitude of currents, the line to line and line to ground voltages under the star- (Y) and delta- (∆) connected configurations in the symmetrical three-phase system. Moreover, it could be used to measure the 3-phase load power capacity by the 1-wattmeter and 2-wattmeter methods. Each process of measuring, calculating and processing results of the software program is verified and retested accurately with the practical experiments. Finally, this paper shows results in the form of tables or graphs within the experiment scopes.
