Wind-Electric Power Potential Assessment for Three Locations in East Java-Indonesia

This paper reports our effort to asses wind energy potentials for three locations in East Java. We used wind speed data over a period of almost 3 years, i.e. in period of June 2006 – August 2008. Data were taken from direct measurement in locations in East Java Province, i.e. Sampang (Madura), Juanda (Surabaya), and Sawahan (Nganjuk). The short-term of wind speed mean in monthly signifies to wi...

A Comparative Analysis of PMSG Drives Based on Vector Control and Direct Control Techniques for Wind Turbine Applications

The control of a permanent magnet synchronous generator (PMSG) drive can be achieved through the implementation of different control techniques. This paper presents a comparative study of vector control and direct control techniques applied to PMSG drives for wind turbine applications. Rotor field oriented control (RFOC) and direct torque control (DTC) are considered for the generator-side conv...
