Description

From the point of view of environment and energy problems, the renewable energies have been attracting attention. However, fluctuating power generation by the renewable energies affects the stability of the power network. Thus, we propose a new electric power storage and stabilization system, Advanced Superconducting Power Conditioning System (ASPCS), which consists of a Superconducting Magnetic Energy Storage (SMES) and a hydrogen - energy - storage converge on a liquid hydrogen station for fuel cell vehicles. A 10 kJ small SMES system, in which Di-BSCCO coil cooled by liquid hydrogen is installed, has been developed to compose an experimental model of the ASPCS. The SMES coil is conductively cooled by liquid hydrogen flow through a thermo-syphon line under a liquid hydrogen buffer tank. A fabrication of the cryogenic system has been completed, and then it was cooled down by liquid hydrogen. The SMES coil has been successfully charged up to a nominal current of 200 A DC. Then Eddy current loss, which is mainly induced in pure aluminum plates pasted onto each pancake coils for conduction cooling, was also measured. Experimental results will be reported.
