Abstract

Motor sinkron sering dipakai kalau diinginkan kecepatan konstan atau faktor kerja yang dapat diubah. Untuk mendapatkan kinerja yang efisien, motor tersebut dioperasikan dengan kecepatan yang variabel. Untuk itu maka frekuensi dari jala-jala harus bisa dikontrol, dan karenanya diperlukan suatu konverter. Untuk mengatur kecepatan dari motor sinkron dapat dilakukan dengan strategi pengaturan Volt/Hertz konstan. Namun metode ini kurang memberikan kinerja yang baik. Karenanya diperlukan suatu sensor arus untuk meningkatkan kinerja motor sinkron. Karena itu metode ini merupakan metode hybrid volt/hertz konstan dan sensor arus. Untuk memperbaiki respon dari sistem digunakan kontroler PI (Proportional & Integral Controller). Hasil penelitian didapatkan respon kecepatan model hybrid volt/hertz-current nilai rise time berkisar 0,2677 pu sampai 0,316 pu, maximum overshoot 0,4% sampai 0,975%, dan settling time 0,048 pu sampai 0,1307 pu. Ini lebih baik dari respon kecepatan model volt/hertz dengan nilai rise time 0,192 pu sampai 0,4398 pu, maximum overshoot 0,6% sampai 3,6%, dan settling time 0,093 pu sampai 0,313 pu. Respon torka pada model hybrid volt/hertz-current osilasinya lebih kecil dengan nilai antara ±1,012 pu sampai ±1,161 pu dibandingkan dengan model volt/hertz, serta performansi arus dari model hybrid volt/hertz-current lebih baik dari performansi arus model volt/hertz.

Synchronous motors are often used when a constant speed or an adjustable power factor is required. To obtain efficient performance, the motor is operated at variable speeds. For this reason, the supply frequency must be controlled, requiring a converter. Speed control of a synchronous motor can be performed using a constant Volt/Hertz control strategy. However, this method delivers suboptimal performance. Therefore, a current sensor is required to improve synchronous motor performance, resulting in a hybrid constant volt/hertz and current sensor method. To improve system response, a PI (Proportional & Integral) Controller is used. The research results show that the speed response of the hybrid volt/hertz-current model has a rise time value ranging from 0.2677 pu to 0.316 pu, maximum overshoot from 0.4% to 0.975%, and settling time from 0.048 pu to 0.1307 pu. This performance is better than the speed response of the volt/hertz model, which has a rise time of 0.192 pu to 0.4398 pu, maximum overshoot of 0.6% to 3.6%, and settling time of 0.093 pu to 0.313 pu. The torque response in the hybrid volt/hertz-current model exhibits smaller oscillations, ranging between ±1.012 pu to ±1.161 pu compared to the volt/hertz model, while the current performance of the hybrid volt/hertz-current model is better than that of the volt/hertz model.
