SIMULATION OF LOW VOLTAGE POWER SUPPLY SYSTEM FOR INDUSTRIAL FACTORY WITH MATLAB SOFTWARE

Abstract

When designing an industrial plant's electrical system, the calculation and selection of appropriate electrical equipment will determine the safe operation of the system. To solve this problem, designers often use simulation modeling software to calculate and survey the operation of the system before coming to a decision on equipment and system selection. The article refers to the survey of a workshop's low-voltage power supply system using Matlab software with the following key contents: (1) Checking the electrical network according to the allowable long-term current conditions; (2) Calculating of losses in the transformer, and obtained simulation results allow conclusions about the selected equipment and system. Surveying and testing low-voltage power supply systems using Matlab software not only solving the optimization problem in power supply system design but also helping students majoring in electrical systems approach reality favorably.
