Multicriteria Decision Approach for Selection of Fault Current Limiters Technology

Abstract

Java Bali power grid become larger because of continous development of power plant. In the other hand, higher power generation leads to higher short circuit current level. One of the solutions to limit this higher fault current is by installing of the fault current limiters (FCL). Selecting the FCL technology is relative complex as it involves multi criteria decision making. To solve it, this study used the analytic network process (ANP) method to find out the priority of FCL technology with respect to the major criteria such as technology, engineering, economic, and impact factor. Seven alternative of FCL technology used in this study were air core reactors (ACR), iron core reactors (ICR), saturable core fault current limiters (SCFCL), resistive superconducting fault current limiters (RSFCL), inductive superconducting fault current limiters (ISFCL), and pyrotechnic current limiters (PCL). Each FCL technology was evaluated and ranked from each stated criteria. FCL technology alternative for each voltage level was presented in this paper to give better justification for FCL technology selection.
