Fault Current Limiter for a Distributed Power System
نویسندگان
چکیده
The up-gradation of an Electrical power generation network results in higher levels of short circuit fault current. Thereby, the existing protection equipment like circuit breakers, isolators and fuses become under capacity and not capable of withstanding higher short circuit currents. Thus the system is highly vulnerable to the adverse effects of short circuits. Replacing the whole protection switchgear is not feasible technically and economically. The solution in such a situation is an equipment called Fault Current Limiter (FCL). The concept of FCL is not new but the most suitable FCL is an on going research subject. This paper covers the prevailing aspects of FCL, the types of FCL, the research progress and at present the most viable FCL solution for industrial purpose at 6.3kV system

Power system protection at transmission and distribution levels based on overcurrent relays is essential based on their properties such as detection, stability, high speed, backup and error correction accuracy. Since distributed generation sources are connected to the power grid, they not only increase the short circuit level of the grid, but also disrupt the set point of main and backup relays...
