Article 25 Voltage stability requirements applicable to AC-connected offshore power park modules
United Kingdom
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.

| Synchronous area | Voltage range | Time period for operation |
|---|---|---|
| Great Britain | 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.
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.
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.
