Abstract
The promotion of recent power system fault current reduction research has been directed towards the super conducting fault current limiters. Many conventional protective devices installed for protection of excessive fault current in electric power systems especially at power stations are circuit breaker tripped by over current relay protection. They have a responds time delay that can pass initial two to three fault current cycles through it before getting activated. Super conducting fault current limiter (SFCL) is innovative electric equipment which has the capability to limit fault current within first cycle. The first cycle suppression of fault current by SFCL results in an increased transient stability of power system carrying higher power with greater stability. This paper presents a wind farm based smart power system with super conducting fault current limiter for wind farm fault current reduction. In this work, a resistive type SFCL model is implemented by integrating Simulink and Sim power system block in Matlab. In addition, typical smart grid model including generation, transmission and distribution network with dispersed energy resource (wind farm) is modeled to determine the performance of SFCL. Three phase fault have been simulated at different locations in smart grid and the fault current analysis is done with and without SFCL.
