Analisis Dan Simulasi Mekanisme Pengasutan Motor Induksi 3 Phasa Menggunakan Inverter Berbasis Matlab
At present, induction motors are the most widely used motors in various applications ranging from applications in the household environment to large industrial applications. Induction motors have many advantages from a technical and economic point of view. However, induction motors also have disadvantages, including large currents that can result in a decrease in system voltage and interfere with the work of other equipment systems in one channel. Therefore researchers are interested in conducting research with the title Analysis and Simulation of 3-Phase Induction Motor Salting Mechanisms Using Matlab-Baseds. The method used in this study is data collection of simulation results carried out in this study. By initializing the type of induction motor and its Parameters. Then making a simulation of changing the DOL and inverter, and then testing it to measure varying load conditions at start and Steady State in RPM, power, transient time and current. After doing the calculation in the form of frequency, angular velocity, transient time, and torque. Then analyze the starting comparison between the DOL and inverter methods, rpm Speed Test analysis, current test analysis, Torque analysis, Transient time analysis and power analysis. Based on the research obtained that the motor in the DOL (direct on line) simulation, the value of the rpm speed is greater than using the method. The greater the load, the smaller the rpm speed. DOL (direct on line) simulation, the value of the current is greater by using a variable load, while using an , the current value is smaller with a percentage difference of 10 - 23%. In the simulation. With this method that the output current value can be set using the angle of the trigger. The change in current is proportional to the change in voltage. So that by providing voltage in stages, the current that occurs does not spike high and is in accordance with the expected settings, such as in the DOL method. In this way, problems with 3 Phase Induction motors can be resolved immediately.
Keywords: rpm speed, Torque, Power, Transient Time and Current.
