Abstract

The autonomous power generation system with DFIG dedicated for diesel driven gensets is presented. Characteristics of torque and power versus speed of internal combustion engine ICE are analyzed at an angle of application in electrical power generation. Features and advantages of variable speed operation versus fixed speed operation of internal combustion engine are described. The vector control method for generation of fixed amplitude and frequency output voltage is presented. The PLL vectorial synchronization of the actual stator voltage with the reference vector allow the rotor speed and position sensorless operation. Variable speed operation of the ICE engine reduces fuel consumption what is important in continuously operated diesel and hybrid systems with renewable sources. Results of standalone operation of 2.2 kW doubly fed induction generator supplying nonlinear load are presented.
