Enhancing the power of quality issues using superconducting magnetic storage devices–based dynamic voltage restorer–aided switched coupled inductor inverter with space vector pulse width modulation techniques

Abstract

This paper emphasizes on proposing a dynamic voltage restorer–based superconducting magnetic storage devices have utilized to power quality issues. Dynamic voltage restorer can be used for different topologies of the inverter. The conventional topology of dynamic voltage restorer possessing voltage source inverter or Z-source inverter is modified into a switched coupled inductor inverter which has the clear edge in power transfer over the former. The versatility of the controller is enhanced by this work by deploying a fuzzy combine discrete wavelet transforms. The proposed system in this paper, switched coupled inductor inverter–based dynamic voltage restorer-superconducting magnetic storage devices on mitigating the interruption, harmonics and voltage sag/swell. The operating of switched coupled inductor inverter has buck/boost function capability and reduced number of passive components. Due to digitalization, higher utilization factor and reduced harmonic content, controller of fuzzy logic–space vector pulse width modulation techniques with filter application of discrete wavelet transform is used to operate of switched coupled inductor inverter. The hysteresis controller is used to perform the superconducting magnetic storage devices device, has the ability in the storage of real power with high energy density and protects the consumer from grid fluctuation. To detect the power quality disturbances quickly response and improve the compensation capability of dynamic voltage restorer-superconducting magnetic storage devices. The whole of the suggested system is simulated in MATLAB/Simulink and realized as a prototype whose control pulses are duly generated and fed by dSPACE 1104 controller.
