Optimal Placement of Resistive Superconducting Fault Current Limiter by
Considering Short-Circuit Current and Transient Stability of Power
System
Abstract
High level of fault currents has become one of the most challenging
issues, along with increased electrical energy consumption and power
grid expansion. However, some of the previous work was limited to
installing limiters on designs and installing them on small plans. In
this study, the optimal placement of a resistive-type superconducting
fault current limiter (RSFCL) to achieve good power system transient
stability is proposed. The proposed method has several advantages.
First, procedure fault analysis is applied to consider the magnitude of
the short-circuit currents and the line located close to the generator
for the placement of the device. Compared with other methods, it can
directly find the exact line to be installed RSFCL. Second, the
stability assessment is validated using the time domain simulation by
installing limiters with varying capacities in any location. Third,
parameters were analysed to evaluate the proposed method’s
effectiveness, including angular speed, rotor angular velocity, and
generator rotor angle in a multi-machine system. The result reveals that
the placement of the limiter on the line with the most significant
short-circuits value on the line closest to the generator increases the
power system stability more than the placement in other locations.
