# Commission Regulation (EU) 2016/631 of 14 April 2016 establishing a network code on requirements for grid connection of generators (Text with EEA relevance), Article 25: Voltage stability requirements applicable to AC-connected offshore power park modules

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

1. Without prejudice to point (a) of Article 14(3) and point (a) of Article 16(3), an AC-connected offshore power park module shall be capable of staying connected to the network and operating within the ranges of the network voltage at the connection point, expressed by the voltage at the connection point related to reference 1 pu voltage, and for the time periods specified in Table 10.
2. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

0.90 pu – 1.10 pu where the voltage base for pu values is below 300kV
Unlimited
0.90 pu – 1.05 pu where the voltage base for pu values is from 300kV to 400kV
Unlimited
1.05 pu – 1.10 pu where the voltage base for pu values is from 300kV to 400kv
15 minutes
The table shows the minimum period during which an AC-connected offshore power park module must be capable of operating over different voltage ranges deviating from the reference 1 pu value without disconnecting.
4. The voltage stability requirements specified respectively in points (b) and (c) of Article 20(2) as well as in Article 21(3) shall apply to any AC-connected offshore power park module.
5. The reactive power capability at maximum capacity specified in point (b) of Article 21(3) shall apply to AC-connected offshore power park modules, except for Table 9. Instead, the requirements of Table 11 shall apply.
