Use of Super Conducting Magnet for Energy Storage in Shunt Active Power Filter

Kumar, Pravesh (2015) Use of Super Conducting Magnet for Energy Storage in Shunt Active Power Filter. MTech thesis.



Huge application of non-linear load and electronics apparatus in power system generates harmonics. That makes the current wave form distorted and causes huge power loss in power system. This problem can be overcome by application of Shunt Active Power Flitter (SAPF). Shunt Active Power Filters in an electric power network can improve the quality of power system by removing harmonics which are generated by non- linear load. In this project, a voltage-source PWM converter, and a Super Conductor Magnet for energy storage is used to design a Shunt Active Power Filter. Earlier use of copper inductor to store the energy for compensation the harmonics in Shunt Active Power Filter causes a power loss, to reduce these power losses instead of copper inductor a Superconductor Magnet is placed in Shunt Active Power Filter. Shunt Active Power Filter is designed by using ‘Instantaneous Power Theory’ or ‘p-q Theory’. Switching pulses for Voltage source converter is generated by using Hysteresis Band Controller. DC/DC is also designed to control the Super Conductor Magnet. Charging and Discharging of Magnet is base switching operation of DC/DC converter. Total Harmonic Distortion (THD) in wave, during charging and discharging of Magnet is calculated and presented in this paper .The results of simulation are satisfied with all the property explained by the theory. This paper describes simulation and evolution of SAPF for removing the harmonics. Simulations are done using MATLAB/Simulink Software and results are presented.
