In this paper, a new superconducting flywheel energy storage system is proposed, whose concept different from other systems. The composed of radial-type magnetic bearing (SMB), an induction motor, and some positioning actuators. SMB stator rotor. rotor suspended by the stator, one end fixed to stable heavy base. Free-run experiments in case unfixed are performed. natural rotation decay curve, d...

A persistent current switch (PCS) is used for superconducting applications, such as superconducting magnetic energy storage (SMES) system. The authors have proposed a mechanical switch of Y-BaCu-O (YBCO) bulk as a mechanical PCS. In previous study, the authors have successfully reduced a residual resistance by depositing with metal on contact surface. This paper focused on a current carrying ar...

The power system network is becoming more complex nowadays so maintaining the stability of the power system is very difficult. So we have designed a 12-pulse based Static Synchronous Series Compensator (SSSC) which is operated with and without integration of Superconducting Magnetic Energy Storage (SMES) for enhancing the voltage stability and power oscillation damping in multi area system. Con...

In this paper a simple but novel control strategy is developed for Superconducting Magnetic Energy Storage (SMES) unit. The SMES unit is used to improve the dynamic performance of power system. The gain of the controller is determined depending on the power system and the capacity of the SMES unit. A simple delayed function is used to determine the desired power from the SMES unit. Eigenvalue a...

A comprehensive digital computer model of the two-area interconnected power system including the governor deadband non-linearity, steam reheat constraints and the boiler dynamics is developed. The improvement in AGC with the addition of a small capacity Superconducting Magnetic Energy Storage (SMES) unit is studied. Time domain simulations are used to study the performance of the power system a...
