영문 초록

Recently, due to the use of fossil fuels for electric power production, carbon emissions increased excessively. Thereby, in order to replace fossil fuels, many studies about fossil fuels such as solar and fuel cell energy source are progressing. Fuel cell system has high energy conversion efficiency. Also, fuel cell system is environmentally friendly system because the carbon emission is almost not occur. Therefore, the fuel cell system is considered as the core technology of in the fields of the future energy and environmental. Fuel cell system has an effect on distribution power system. because it is another power source type of different with large power plants. So, fuel cell system can be degradation reason of power quality in the power system. In this paper, we constructed the system for an assessment on ground fault effect. The system is composed with power source, linear load, fuel cell system. We also performed assessment on ground fault effect in customer and the distributed power system during grid connection of residential fuel cell system. An assessment cases are divided into the four. The result of the evaluation, the ground fault does not significantly affect on the system, However, we can confirmed that with increasing number of distributed power may cause secondary accidents.
