In this paper, the impacts of installing superconducting fault current limiter (SFCL)in radial and loop power distribution system are evaluated to improve voltage sag in both cases of with and without distributed generations (DG). Among various SFCLs, the hybrid type with a superconducting element in parallel with a current limiting reactor (CLR) is selected. This is more effective than resisto...

This paper presents a direct torque control (DTC) of induction motor drive (IMD) using Different levels of Cascade Multilevel DVR. The DTC is one of the most excellent strategies of flux ripples control and torque of IMD. The main drawback of the DTC of IMD using conventional PI controller based SR is high torque, stator flux ripples and speed of IMD is decreasing under transient and steady sta...

Custom Power devices like Dynamic voltage restorer and STATCOM are normally employed as a solution for mitigation of power quality problems like voltage sag and swell. In this paper new voltage sag compensators based on an autotransformer and an IGBT switched by PWM technique and Hysteresis Voltage Control (HVC) method are compared. These two schemes are able to recognize the voltage sag condit...

A constant power supply is a basic need for each consumer due to the increase in sensitive equipment day by day. As per IEEE standards, 10% reduction voltage from not acceptable and may cause failure of equipment. Previously, different techniques have been used alleviate sag, such as STATCOM, DSTATCOM, SVC, shunt capacitors, but these devices are connected parallel, which compensates low value ...
