SCHENECTADY, NY -- General Electric (GE) reports that a demonstration model for a new, high-temperature superconducting (HTS) generator has been successfully tested. The development program is expected to lead to a higher efficiency generator capable of providing millions of dollars in energy savings.
"Improving generator efficiency has national importance since generators are the source of all conventional power plant electricity. The successful testing of the demonstration model validates GE's design approach to not only increase efficiency, but also address customer cost and reliability needs," said James Daley, lead physicist for the superconductivity program of the U.S. Department of Energy (DOE).
In late 2001, GE received a $12.3 million contract from the DOE to support a 3.5-year program to move HTS generator technology toward full commercialization. In October 2002, DOE officials met with representatives of GE Power Systems and the GE Global Research Center to formally kick off the program.
In a significant milestone for the development project, a 1.8 mega volt-ampere (MVA) proof-of-concept model for the rotor, cryo-refrigeration and HTS subsystems has been designed, manufactured, and tested. Results of the tests will be scaled to a 100-MVA prototype generator that will be fully tested under load.
