Abstract

Sistem eksitasi merupakan komponen yang sangat penting dalam pengoprasian mesin generator. Fungsi dari sistem eksitasi pada generator adalah untuk mengendalikan output dari generator agar tetap stabil pada beban yag bervariansi. Arus dan tegangan eksitasi yang masuk ke generator harus dapat diatur agar tetap berada dalam batas tegangan dan arus yang diinginkan. Eksitasi yang berlebihan pada generator dapan memperpendek umur kerja sistem. Kekurangan eksitasi pada generator dapat menyebabkan menurunnya torsi pada sat starting torque pada motor listrik. Untuk menghindari hal tersebut maka arus dan tegangan eksitasi yang masuk kedalam generator harus dimonitoring terlebih dahulu. Pada penelitian tugas akir kali ini telah dilakukan perancangan sistem monitoring arus dan tegangan pada keluaran panel eksitasi. Sistem ini terdiri atas modul sensor tegangan yang menggunakan prinsip pembagi tegangan dan modul sensor arus, mikrokontroler stm32f407vg, display LCD 16x2 dan sistem penyimpanan dengan software STM studio. Monitoring ini dilakukan dengan memberikan beban pada generator. Alat ukur ini menghasilkan pengukuran tegangan dengan nilai ketidakpatian ± 0,69 sebesar sedangkan pengukuran arus memiliki nilai ketidakpastian sebesar ±0,67 dengan tingkat kepercayaan 95%

The excitation system is a very important component in the operation of the generator engine. Excitation systems play an important role in regulating power and improving the system of electric power stability. The function of the excitation system in the generator is to control the output of the generator to remain stable in the load which is varied. The current and excitation voltage that enters the generator must be set to remain within the desired voltage and current limits. Excessive excitation of the generator can shorten the working life of the system. The lack of excitation in the generator can cause a decrease in torque at the starting torque on the electric motor. To avoid this, the excitation current and voltage entering the generator must be monitored first. In this final assignment research the current monitoring system and tegangfan have been carried out at the excitation panel output. This system consists of a voltage sensor module that uses the principle of a voltage divider and current sensor module that uses the principle of a dc ampere meter, a stm32f407vg microcontroller, a 16x2 LCD display and a storage system with STM studio software. This monitoring is done by giving a load to the generator. This measuring instrument produces a voltage measurement with a value of ± 0.69 for non-negativity while the current measurement has an uncertainty value of ± 0.67 with a confidence level of 95%.
