Annex VIII Reactive power and voltage requirements referred to in Article 48

United Kingdom

Voltage range	Time period for operation
F10.85 pu-F20.90 pu	60 minutes
0.90 pu-F31.10 pu	Unlimited
1.10 pu-F41.12 pu	Unlimited, unless specified otherwise by the relevant system operator, in coordination with the relevant TSO.
1.12 pu-F51.15 pu	To be specified by the relevant system operator, in coordination with the relevant TSO.

Table 12: Minimum time periods for which a remote-end HVDC converter station shall be capable of operating for different voltages deviating from a reference 1 pu value without disconnecting from the network where the voltage base for pu values is from 110 kV to (not including) 300 kV.

Voltage range	Time period for operation
F60.85 pu-F70.90 pu	60 minutes
0.90 pu-F81.05 pu	Unlimited
1.05 pu-F91.15 pu	To be specified by the relevant system operator, in coordination with the relevant TSO. Various sub-ranges of voltage withstand capability may be specified.

Table 13: Minimum time periods for which a remote-end HVDC converter station shall be capable of operating for different voltages deviating from a reference 1 pu value without disconnecting from the network where the voltage base for pu values is from 300 kV to 400 kV (included).

Maximum range of Q/Pmax	Maximum range of steady-state voltage level in PU
F100.95	F110.225
