I accept the conditions.
Mains Protection operates to reduce the risk of a generator running
‘islanding’: where a section of the network is cut off from the wider network.
The protection should only operate in an ‘islanded’ situation but occasionally,
and more recently more often, it has operated for other network faults causing
nuisance tripping for generators and the wider network. Previously vector shift
and very sensitive RoCoF equipment was used as protection, but network events
in 2018 and 2019 have identified the need for different protection measures.
does it mean for me and my connection?
already connected generators will require to review their Loss of Mains
protection to ensure they comply with the new measures. If you are using vector shift or more
sensitive RoCoF then you will need to disable, modify or even replace your
protection to ensure the required settings are in place by the 1st September
2022. This will bring all generators in line with new standards, many of which
have been in place for connecting generators over 5MW since 2014.
Accelerated Programme allows most generators not yet complaint with the new
requirements to apply for funding towards the cost of modifying or installing
the new protection settings.
