A Comprehensive Review of DC Fault Current Limiters for DC Renewable Energy Generators

As DC renewable energy generators extensive development in the recent years, the need for applicable protection methods has vitally increased. Solar panels, wind turbines, combined heat and power, and solar thermal panels are all vulnerable power generators in DC renewable energy which necessarily need to be preserved from DC fault current. However, DC renewable energy are difficult to control and protect in the fault case even though they are easy to use in the normal state. Short circuits and Potential risks are controlled with protective equipment based on fault current. There is a fundamental role for fault current limiters (FCL) in creating these disparities. In this paper, DC FCLs as vital equipment to protect DC renewable energy will reviewed and than a comprehensive summary of the limiters are presented and compared.
