HTS inductive energy controlled discharging circuit & its application in the design of UPS

Shrivastava, Raj (2014) HTS inductive energy controlled discharging circuit & its application in the design of UPS. MTech thesis.



High temperature superconducting magnet (HTS) inductive energy charging and discharging characteristics and its nature has been theoretically dealt in this report and its detailed analysis by specific models and graphs has been presented so as to portray light on the future advancement in this field with the design of UPS. All the design are done using SIMULINK/MATLAB and the charging and discharging characteristics shows the advantage of HTS. And, this simulation results will support the development of UPS (uninterruptible power source) using the SMES technology with substantial great advantages. Superconducting Magnetic Energy Storage is a novel technology that stores electricity from the grid within the magnetic field of a coil comprised of superconducting wires with near zero loss of energy. SMES is a grid enabling device that stores and release large quantities of power almost instantaneously. The organization is capable of releasing high levels of ability within a fraction of a cycle to replace sudden loss or dip in line power. Strategic injection of brief bursts of power can play a crucial part in maintaining grid reliability, especially with today increasingly congested power lines and the high penetration of renewable energy sources such as wind and solar. A typical SMES consists of two parts- cryogenically cooled superconducting coil and power conditioning system which are motionless and result in higher reliability than many other power storage devices. Ideally, once the superconductivity coil is charged, the current will not decay and the magnetic energy can be stored indefinitely.
