Abstract:
In this paper, a method to compute optimum impedance of fault current limiter (FCL) is presented. The type of FCL impedance based on its resistance, inductance and capacitance has an effect on the amount of short circuit current reduction. Therefore, for an optimum result a complex parameter is selected for the FCL impedance. In addition, magnitude of short circuit current is also affected by location of FCL and the amount of system parameter. Due to the cost difference of real and imaginary components of FCL impedance, this calculation is based of sensitivity analysis, such that while minimizing the cost of impedance parts for FCL, reduction in fault current is maximized. Moreover, based on the maximum allowable current constraint and using a developed computer program, an optimum FCL impedance for a wide range of prices for real and imaginary components are computed. These analyses were applied on a 11 bus test system with using a specified single location of FCL.
