Abstract

In this paper, it was assumed that a synchronous generator in a customer system was connected to a distribution system via the fault current limiter (FCL). We theoretically investigated the influence of the output power of the generator on the limiting effect of the fault current when the three-phase short-circuit fault occurs. It was shown that the fault current out of the customer system, limited by the FCL, rises with the output power of generator. It was found that the larger the output power is, the higher the fault current at the fault point is when the limiting resistance is less than 15 Ω in the case of the resistive type FCL. On the other hand, the fault current at the fault point decreases with an increase in the output power for the limiting resistance more than 15 Ω. By contrast, it was found that the suppressing effect on the fault current at the fault point due to the inductive type FCL hardly depends on the output power.
