Abstract
Use of HVDC links for direct connection of a large
nuclear power station to the existing power grid is unprecedented.
Control of such HVDC connection for stable and secure operation
of the nuclear power station is challenging and untested. For
the Moorside nuclear power station planned close to the Lake
District in Great Britain, there is tremendous pressure to use
HVDC cables for the southern connection route (which would
pass through the picturesque landscape) to avoid the visual
impact of overhead lines. This paper shows that it is feasible
to connect a large nuclear power station, such as Moorside,
through a VSC-HVDC cable route alongside a northern AC
route where there are no objections to overhead transmission.
Use of a proposed control of the VSC-HVDC is shown to achieve
automatic and rapid redirection of power on to the VSC-HVDC
link following sudden outage of the AC route. Moreover, if the
generators at Moorside were to shut down accidentally, the same
control strategy for VSC-HVDC can back feed the power station
auxiliaries which is essential for nuclear safety. Thus, a mix of
AC and HVDC connection routes achieves similar (if not better)
transient responses as compared to using both AC routes which
in this case faces serious opposition.
