Design of a novel pulse capacitor charge power system based on inertial energy storage

In this paper, a novel high-voltage generator-Homopolar Inductor Alternator (HIA) pulse-charge for the capacitor bank with repetitive frequency though inertial energy storage system has been designed. A diesel engine provides energy as a prime motor in this system, and then drives the HIA to the rated speed by the flywheel energy storage device, the AC pulse-charge for the capacitor bank with repetitive frequency through power electronic conversion. We have introduced the theory of the HIA and the operation mode of this system, and we have analyzed the rotor speed change according to the principle of energy conservation. Based on the main physical characteristics of IGCT, a functional model has been investigated and realized with the simulation tool of PSIM package. Finally, we have set up the main circuit topology for this system, and verified its feasibility though the analysis of the circuit simulation by Simulink package.
