PERANCANGAN KONTROLER LOGIKA FUZZY DENGAN PREDIKTOR HARMONISA JARINGAN SYARAF TIRUAN UNTUK MENGENDALIKAN RANGKAIAN SWITCHING PADA FILTER AKTIF

ABSTRAK

Sistem distribusi merupakan bagian dari sistem tenaga listrik yang berfungsi untuk menyalurkan dan mendistribusikan daya listrik ke pusat-pusat beban atau konsumen. Jika pada sistem distribusi sering didapati adanya distorsi harmonisa maka akan mempenganihi kualitas daya listrik yang disalurkan. Salah satu cara untuk mengatasi terjadinya tegangan harmonisa adalah dengan menggunakan filter aktif yang dapat menyuntikkan tegangan kompensasi sehingga dapat mengurangi besamya gangguan. Dalam penelitian ini dirancang suatu filter aktif yang menggunakan transformator daya untuk menyuntikkan tegangan kompensasi berdasarkan hasil prediksi dan identifikasi Jaringan Syaraf Tiruan JST. Besamya tegangan kompensasi ditentukan melalui proses switching yang diatur oleh kontroler logika fuzzy. Hasil simulasi menunjukkan bahwa filter aktif yang dirancang mampu menurunkan Total Harmonic Distortion THD sampai 29.4665 untuk gangguan harmonisa dan 275.524 untuk spike.


ABSTRACT

Distribution systems is a part of electrical power systems which distribute electrical energy to the consuments. While there are many harmonics in distribution systems it will be decrease the power quality. Active filter can be used to eliminate harmonics by injection the compensation voltage. This research designs an active filter that will inject the compensation voltage via transformer based on predictive and recognitive results by Artificial Neural Networks ANN. The compensation voltage desired from switching process by fuzzy logic controller. The simulation result shows that the designed active filter improve the sinusoid shape in transformer output. It can decrease the Total Harmonic Distortion THD up to 29.4665 for the harmonics distortion and up to 275.524 for the spike distortion.
