ABSTRAK

Perkembangan teknologi elektronika daya saat ini memungkinkan solusi teknis dalam merancang suatu alat untuk mempertahankan kualitas tegangan. Gangguan kedip tegangan voltage sag dan interruption merupakan permasalahan kualitas daya listrik yang berkaitan dengan kualitas tegangan. Untuk mengatasi permasalahan tersebut dipakai metode injeksi tegangan menggunakan peralatan elektronika daya Dynamic Voltage Restorer DVR. Berdasarkan kemiripan komponen dan cara kerjanya DVR dimodifikasi untuk difungsikan sebagai pemulih kedip tegangan dan Uninterruptible Power Supply UPS. Tugas akhir ini membahas DVR menggunakan Fuzzy Logic Controller FLC sebagai sistem kendalinya. Simulasi dengan simulink Matlab dan perancangan prototype DVR menggunakan metode interfacing dengan komputer sebagai sistem kontrolnya dilakukan untuk menguji kinerja DVR. Perbandingan hasil simulasi dan pengujian prototype DVR menunjukkan bahwa saat terjadi kedip tegangan 50 DVR bekerja mengembalikan tegangan beban menjadi 1 perunit pu dengan nilai error 3.3 . Pemulihan tegangan beban hasil simulasi lebih baik jika dibandingkan dengan hasil pengujian prototype


ABSTRACT

Nowadays Development of power electronic technology may allow technical solution on projecting device to maintain voltage quality. Voltage sags and interruptions are power quality problem that have connection with voltage quality. Dynamic Voltage Restorer DVR with voltage injection is the method used to solve this problem. Based on equality of parts and its works DVR modificated as voltage sags correction and Uninterruptible Power Supply UPS. This Final Project discuss about DVR using Fuzzy Logic Controller FLC as control system. Simulation with Matlab simulink and modelling DVR prototype using computer interfacing method as its control system is used to test DVR performance. Simulation result and DVR prototype test result comparison show that DVR can recover the load voltage become 1 perunit pu with error value 33 when voltage sag 50 is occured. Load voltage recovery simulation result better than prototype test result.
