Comparison between SFCL and TSC for voltage stability enhancement of wind generator system
Abstract
This work proposes superconducting fault current limiter (SFCL) device to enhance voltage stability of the fixed-speed wind generator system. In order to evaluate the effectiveness of the proposed SFCL methodology in detail, its performance is compared to that of the thyristor switched capacitor (TSC). The comparison is done in terms of voltage stability enhancement, controller complexity and cost. The effectiveness of the proposed methodology is tested considering both permanent and temporary faults in the power system model consisting of a wind generator and a synchronous generator. In order to evaluate the system performance, we have used indices in terms of terminal voltage deviation and real power deviation of the wind generator. Simulations are performed through Matlab/Simulink software. Simulation results show that both the SFCL and TSC are effective in limiting the fault current as well as minimization of the voltage sag of the wind generator system. However, the performance of the SFCL is somewhat better than that of the TSC. Therefore, the proposed SFCL can be considered as an effective means of the voltage stability enhancement of wind generator system. © 2013 IEEE.
