Fault Ride Through Capability Enhancement of Grid-Connected Fuel Cell System by SDBR

Abstract

To meet the national grid operational requirements, the fuel cells distributed generation (DG) system must be connected to the grid through some control devices to maintain the fault ride through capability during the fault. In this work, a Series Dynamic Braking Resistor (SDBR) methodology is proposed to enhance the low voltage ride through capability of the fuel cell during any fault in a power distribution network. In order to show the effectiveness of the proposed SDBR technology in improving the fault ride through capability of the grid connected fuel cell system, both balanced and unbalanced faults have been considered in the power network. Simulation results obtained through the MATLAB/Simulink software show that the proposed SDBR is capable of improving the fault ride through capability of the grid connected fuel cell system.
