Abstract

Telah banyak dilakukan studi mengenai fenomena inrush current. Inrush current merupakan fenomena yang terjadi pada saat transformator pertama kali diberikan sumber tegangan. Inrush current dapat dianalisa menggunakan kurva magnetisasi pada inti transformator. Pada studi ini, dilakukan simulasi menggunakan perangkat lunak untuk mengetahui pengaruh cara pemotongan inti transformator terhadap kurva magnetisasi. Sedangkan perhitungan matematis dilakukan untuk mendapatkan nilai puncak dari inrush current

Abstract

This paper presents a  system wind turbine in order to have continously electricity supply for 20 kV grid. Output wind turbine controlled by dc-dc boost converter to produce maximum power in order to obtain the MPP (Maximum Power Point). Output of the converter is controlled by fuzzy logic to obtain the MPP (Maximum Power Point) wind turbine, thus the efficiency  wind turbine can be increased. The system of wind turbine is connected to 20 kV grid. From the simulation using matlab 2010 can be conclude that the controller can shift power to 75 % maximum power of wind turbine. DOI: http://dx.doi.org/10.11591/telkomnika.v13i3.7167
