Apparatus and Experiment of High Temperature Superconducting Magnetic Energy Storage Used for Power System Stability Enhancement

Providing appropriate power compensation is an effective way to keep the stability in power systems. superconducting magnetic energy storage control system is a new kind of power stability control device which utilizes superconductivity technology, power electronics and control theory. This opens a new way to improve power system stabilities. In order to promote the application of such control device and to further investigate the properties of the controller, a prototype of such control device was developed. In the developed prototype, the conduction cooling and the high temperature superconductive techniques are used. The performance of the device is experimentally investigated in two ways, one is an off-line power condition and the other is an on-line power system. Very encouraging results are obtained. Based on a brief introduction of the SMES control system and the principle of using such device to enhance power system stabilities, details of the configuration for the developed device are given in this paper. Test results as well as the analysis of the developed device are also given.
