Experiment Study on Power Regulation Characteristc for High Temperature Superconducting Magnetic Energy Storage Device

Based on a direct cooling high temperature Superconducting Magnetic Energy Storage(SMES) system developed by the authors,this paper investigates the performance of the SMES used for power regulation by experiments.The zero resistance is one of the most important properties of the superconducting material.This property provides us with a way to effectively storage energy,which can be used in many industrial aspects.This paper investigates the property of the SMES cooperating with a current source converter in the power regulation.The procedures and the properties of the energy storage,the active power regulation,and the reactive power regulation for the developed SMES are investigated by the experiment test.Test results show that the fast and effective exchange of the active and reactive power can be realized.This provides a possibility of using SMES to realize different kind of power system control equipments,such as the power system stability control,the power system reactive power compensator,etc.
