Abstract
This manuscript presents the unity power factor (UPF) operation and load leveling of diesel generator (DG) set. The proposed system comprises a wound field synchronous generator driven by diesel engine run at a constant speed. A pulse width modulated voltage source converter (PWM-VSC) is used to supply the reactive power demand of the load. DC link of VSC has a battery for achieving the load leveling. The system is designed in such a manner that battery supplies the real power to the load during over load periods and stores the energy during light loads so that current drawn from generator is always optimal from 80 % to 100% of its rated capacity of the generator. The load leveling assists in optimization of fuel efficiency of diesel engine. In addition the use of PWM-VSC helps in harmonics elimination and load balancing. A control algorithm based on composite state observer has been used in the proposed DG set system to generate the gating pulses of PWM-VSC.
