Due to its many advantages such as the improved power quality, high energy efficiency and controllability, etc. the variable speed wind turbine using a doubly fed induction generator (DFIG) is becoming a popular concept and thus the modeling of the DFIG based wind turbine and improvement in the transient fault conditions is an important consideration. In this paper, Transient stability improvement has been done by using Superfluous Fault Current Limiter [SFCL]. A new design of SFCL IGBT- Bridge-type SFCL shunted with a variable resistor Rsh has been proposed. Rsh is modeled to decrease the terminal voltage deviation to minimum level by reducing the amount of current at the bus terminal. Comparison of Voltage deviation and current deviation with the resistive type SFCL and IGBT- bridge-type SFCL show considerable decrease in both quantities by using IGBT- bridge-type SFCL. The values of voltage deviation at the bus terminal is 8.223 e-8 % for proposed SFCL which is less than the resistive type SFCL that is, 14.4 e-8 %.  The huge voltage sag has been considerably reduced by reduction of high level of current to 0.0004401 % in IGBT-bridge-Type SFCL from 0.0004624% in resistive type SFCL. Thus proposed SFCL has caused significant improvement in transient stability keeping the deviation in active and reactive power during faults to minimum level.

Trip Time

The penetration of wind turbine generators onto the grid has grown worldwide at unprecedented rates in recent years. This raises the concern that the tripping of wind turbine generators could potentially cause system collapses. To alleviate these concerns, wind turbine generators need to maintain connection with the grid when a grid fault occurs. This has provoked many countries to adopt low-voltage ride-through (LVRT) for wind turbine generators. The LVRT is the capability of wind turbine generators to maintain connectivity during certain periods of voltage sag. The wind turbine generators should be connected to the grid to support fault recovery. Also, wind turbine generators must provide reactive power according to the grid voltage sag. Therefore, much research has been focused on enhancing LVRT capability. To enhance LVRT capability, this paper proposes the application of a superconducting fault current limiter (SFCL) in the system. The fault current was suppressed and the voltage sag was improved through the application of the SFCL. By improving the voltage sag, the wind turbine generator and the grid were able to maintain a connection. However, suppression of the fault current can cause a problem in the overcurrent relay (OCR) trip time delay. The trip time delay was solved by OCR resetting. Through a power system computer-aided design/electromagnetic transients including DC (PSCAD/EMTDC), the enhancement of LVRT capability and improvement of the trip delay was confirmed.
