Abstract:

Over the years there has been a drastic increase in the usage of number of renewable energy resources like solar energy, wind energy etc. They exist in islanded as well as in interconnected mode with the utility system. Use of fault current limiter is an efficient way of improving the reliability of a micro grid. This paper discusses a bridge type converter based fault current limiter (FCL) having energy management capabilities. The FCL can act both as a protective device and as an energy management device. The FCL is implemented using a bridge rectifier and a boost converter. The inductor used in the boost converter is used for limiting the current during fault conditions. The energy stored in the inductor during faulted as well as normal condition is boosted and is used for powering dc loads. The dynamic analysis of the FCL is done in MATLAB Simulink. A prototype hardware model of the fault current limiter is implemented and tested to verify the effectiveness of the circuit.
