# Commission Regulation (EU) 2016/1447 of 26 August 2016 establishing a network code on requirements for grid connection of high voltage direct current systems and direct current-connected power park modules (Text with EEA relevance), Annex VIII: Reactive power and voltage requirements referred to in Article 48

Extent: E+W+S+N.I.

Voltage range
Time period for operation
0.85 pu-0.90 pu
60 minutes
0.90 pu-1.10 pu
Unlimited
1.10 pu-1.12 pu
Unlimited, unless specified otherwise by the relevant system operator, in coordination with the relevant TSO.
1.12 pu-1.15 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
0.85 pu-0.90 pu
60 minutes
0.90 pu-1.05 pu
Unlimited
1.05 pu-1.15 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
0.95
0.225
