Abstract

This paper introduces the High Temperature Superconducting Fault Current Limiter (HTS-FCL) as a novel technology for mitigating the high fault currents and enhancing the security of Abu Dhabi Water and Electricity Authority (ADWEA) power system. The transient model of ADWEA power system is developed using the PSCAD/EMTDC simulation program. The transient model is validated in steady state and short circuit analysis with the PSS/E model of ADWEA power system. The proposed model is used to facilitate performing the electromagnetic transient studies for installing the HTS-FCL. The detailed time domain model of the HTS-FCL considering its major components, operation control algorithm, sequence of events and fault detection techniques are developed. The implementation of the HTS-FCLs in the 132-kV network of ADWEA power system is studied. Furthermore, the short-circuit currents levels to utilize all potential system equipments and remove the limitations on the available generation are analyzed. The reduction of the fault currents are evaluated at the buses of suspected high fault currents with installing the HTS-FCL to demonstrate its effectiveness for improving the system performance, reliability and security.
