Fuel cell is an emerging energy source, which is characterized with advantages feature like non dependency of environment conditions, clean source of power generation etc. Use of fuel in grid independent operation may be attributed with challenges like load transients and voltage unbalancing. The paper presents and innovative approach to mitigate the challenges face during the grid independent operation...
This paper intends to investigate the operation of a proton exchange membrane fuel cell system (PEMFC) under stand alone and grid connected operation mode when it is subjected to dynamic disturbance at the point of common coupling (PCC) in a distributed generation (DG) system. Monitoring of critical parameters in the system such as active power delivered by the system, PCC side frequency, anode channel...
Load commutated inverter (LCI)-fed wound field synchronous motor drives are used for medium-voltage high-power drive applications. This drive suffers from drawbacks such as complex starting procedure, sixth harmonic torque pulsations, quasi square wave motor current, notches in the terminal voltages, etc. In this paper, a hybrid converter circuit, consisting of an LCI and a voltage source inverter...
