Designing and Analysis of Power System with SFCL Module

In most highly developed electrical power system, there are several difficulties related from generation to distribution. Usually, power generation is located at remote area from the load center. Long transmission and distribution lines have to be constructed and maintained to meet required reliability, power quality and economic point of views. Reliable, cheap, efficient conductor is required to support desirable electric power systems. Now a days we are going for smart grid, so the distribution generation comes in electrical market or system. For such a upcoming smart grid, superconducting fault current limiters (SFCL) has important application on the reduction of abnormal fault current to its possible effect and the suitable location in the micro grids. Micro grids may not be connected with conventional power grid because of their modes of operation. The safety measures for integration with various kinds of distributed generation and loads are taken. However, newly emerging problems due to these integrations are also of severe expected by direct connection of distribution with the power grid are the excessive increase in fault current and the islanding issue which is caused when, despite a fault in the power grid, distributed generation keeps on providing power to fault-state network. Thus in recent power system, fault current reduction research has been directed towards the super conducting fault current limiters. This paper presents a resistive type SFCL model is implemented by integrating in Simulink-Matlab. The various faults have been simulated at different locations in smart grid and the fault current analysis is done with SFCL and without SFCL.
