The paper is devoted to testing of a brushless exciter intended for a 1 MVA high-temperature superconductive (HTSC) synchronous generator. It was decided to make a ambient-temperature version on the 1-st stage with a latter transaction to a cryogenically-cooled version. The exciter incorporates a number of nanomaterials: rare-earth Nd-Fe-B magnets and magnetic cores, manufactured of amorphous alloy tape.
The paper presents results of mathematical modeling of mutual operation of electromechanical energy converters: high temperature superconductive (HTSC) synchronous generators and motors. It includes modes of operation of synchronous alternator and synchronous motor, mutual operation of alternators of comparable rating in an autonomous energy installation, mutual operation of synchronous HTSC motor and semi-conductive converter, influence of semi-conductive converter on the loss value in HTSC armature windings. In all cases specific features of HTSC electrical machines and their parameters and peculiarities of HTSC windings are accounted for with imposed restrictions on the current and magnetic flux variation velocity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
