The Effect of Resistive-type Superconducting Fault Current Limiters on the Test Feeder with Wind-turbine Generation System

Abstract

This paper describes the study to analyze the effect of the resistive-type superconducting fault current limiters (RSFCLs) on the test feeder with the wind-turbine generation, which is a representative renewable energy source. The presented test case is the IEEE 34-bus test feeder augmented with two induction machines that would be typical of wind generation. It is worthy to mention that wind-turbines which are only squirrel-cage induction generator have been considered. The connection of wind-turbines to existing distribution networks may lead to the increasing fault levels beyond the capacity of existing switchgear. This can aggravate the reliability of the overall power system. The short-circuit currents are expected to be controlled by RSFCL. The analysis investigates the effectiveness of using RSFCL as remedial measures for fault level management in a wind power system. As a result, the highly efficient operation of the wind power system becomes more possible by introducing the RSFCL. All models are developed in the time-domain PSCAD/EMTDC dynamic simulation.
