Abstract

Penggunaan dari motor induksi sangatlah luas karena motor ini harganya murah, desain yang sedehana, dan memiliki keandalan yang tinggi. Untuk dapat bekerja sesuai dengan kebutuhan para penggunannya, peralatan elektronika daya, seperti PWM inverter, digunakan untuk mengendalikan dan memperluas daerah kerja dari motor induksi. Pengendalian motor induksi dengan menggunakan PWM inverter dapat dilakukan dengan mengatur nilai tegangan dan frekuensi masukan pada sisi stator dari motor induksi. Pada penelitian ini, karakteristik dari motor induksi dengan sumber PWM inverter disimulasikan dengan menggunakan program SIMULINK dari MATLAB . Motor induksi yang digunakan adalah rotor tipe sangkar dan simulasi dilakukan dengan cara memvariasikan nilai frekuensi masukan stator dan juga indeks modulasi, dengan demikian akan didapatkan nilai torsi elektromagnetik dan kecepatan putar rotor dari motor induksi. Dari hasil simulasi tersebut akan dianalisa pengaruh frekuensi dan amplitudo tegangan masukan pada nilai torsi elektromagnetik dan kecepatan putaran rotor.

Abstract

To meet the needs of small or large scale electricity supply, the use of electrical energy generally uses 1 phase electricity and 3 phase electricity which is used to operate electrical equipment. To be able to find out the voltage, current, and electrical power of the low-voltage distribution network, manual checks are carried out on each R, S, T phase which is on the low-voltage distribution panel. When a 3-phase power failure occurs, it is often difficult to identify which phase is failingSo that in this case it is considered less efficient, for this research is expected to overcome the problems that have been identified. So a tool is made that can monitor failures in the R, S, and T phases which functions as safety when a failure occurs and can display a notification in which phase a failure occurs.In this study, the PZEM-004T sensor, Wemos D1 mini-module, and Android Studio are used which can allow for remote monitoring using electronic devices that have installed applications that have been created. when an error occurs, the "reset" button on the monitoring application is used to reset the protection to restore the device. The current difference in the avometer is 1.48A and the sensor is 1.46A and the current flowing to the load is written 1.88A. The contactor works when the relay receives a command from the Arduino nano with a fast time: 1.60 seconds on the first try, 1.72 seconds on the second experiment, and 1.68 seconds on the third experiment.
