Application of SMES in Wind Generator Controlled by 12 pulse converter

Abstract

Superconducting magnetic energy storage systems are getting increasing interest in applications of power flow stabilization and control in the transmission network level. This trend is mainly supported by the rising integration of large scale wind energy power plants into the high-power utility system and by major features of SMES units. Due to arbitrary variations of wind speed, Load fluctuation is occurred. So minimization of fluctuation is essential for power system security. This paper represent SMES strategy to reduce load fluctuation in wind generation system. 12 pulse converter is the core of a SMES system. 12 pulse converter has the certain freedom in choosing active & Reactive power. By utilizing the reactive power modulation capacity of the converter, the inductor-converter unit of function as a static VAR controller using a switched capacitor bank, while acting as a load frequency stabilizer at the same time.The converter is a voltage source converter with a controller. Superconducting magnetic energy storage (SMES) technology is one of the most active research areas of applied superconductivity in the recent years especially after the high temperature superconducting (HTS) materials were discovered.
