AREVA’s Transmission and Distribution (T&D) division and
Bruker Energy & Supercon Technologies (BEST) have successfully
designed, built and tested a single module of a 13 MVA (2000 A, 6.4
kV) single-phase, shielded-type inductive superconducting fault
current limiter (SFCL) at the AREVA T&D Technology Centre in
Stafford, UK. The design utilizes a proprietary cryogenic module
incorporating BEST’s 2nd generation high-temperature
superconductors.
Increasing demand for electricity and the restructuring of the
power transmission system resulting from deregulation and the
increased level of distributed and renewable energy generation can
lead to fault current levels above the capability of existing
switchgear. A viable solution is to install a current-limiting
device that is self-triggering, rapidly-activated within a few
milliseconds and fail-safe.
As a result of the tests in Stafford, the following conclusions
were drawn:
- The SFCL module limited a
prospective 68.5 kApeak fault to 9 kApeak in five milliseconds (¼
cycle)
- Fault current after five cycles
(before circuit breaker opening) was reduced by a factor of 10
- The SFCL exhibits fast recovery
after a short circuit fault (less than 200 milliseconds) and is
expected to withstand a large number of limitation sequences
Commenting on the successful collaboration with BEST on these
tests, Gerhard Seyrling, Innovation & Performance Improvement
Senior Vice President of AREVA T&D, said, “This product
addresses issues with high fault currents that our customers are
very concerned with in their networks. We intend to work with BEST
to create an industrialized product which will make our customers’
grids smarter and further enable integration of distributed
generation. This breakthrough technology is set to play an
increasingly important role in the future development of smart
grids.”
“Based on these excellent test results, the feasibility of
operation for our shielded, inductive SFCL has been demonstrated,
paving the way for future commercialization,” said Dr. Burkhard
Prause, President and CEO of BEST. “The SFCL certainly meets the
expectations for reliability and durability of the most demanding
utilities, while at the same time it is a true ‘smart grid’ device
with its ability to rapidly react and recover independent of
outside control or triggering.”
