Explanation of CC.S2.3.2 Figure 1 - Minimum reactive
Capability of Wind Farm Power Stations
Connected
to the
Transmission System
at 132 kV and above when operating
in various modes.
WFPSs
must be capable of responding to variations in the
voltage of the
System
in accordance with
CC
5.4.
For the avoidance of doubt,

corre-
sponds to a
Power Factor
range at full
Output
of 0.95 lead
to 0.95 lag.
(b)
Each
WFPS Connected
to the 33 kV
System
must be cap-
able
of
operating
at
its
Registered
Capacity
in
a
stable manner within the following
Power Factor
ranges:
Type
A
Generating
Units
0.95
absorbing
-
0.98
absorbing (lead)
Type B Generating Units
0.95 absorbing - 0.98 gen-
erating (lag)
In this paragraph
Type A Generating Units
means
Induction Generating Units
and
Type B Generating Units
means:
(a)
Synchronous
Generating
Units
of
Registered
Capacity
5
MW
and above; and
(b)
Generating Units
of all types
Connected
in part or in
total through convertor technology with a
Registered
Capacity
of 5 MW and above.
Each
Generating Unit
with a
Registered Capacity
of
5
MW
or more shall have a minimum
Reactive Power
cap-
ability at its
Registered Capacity
as described in the fol-
lowing diagrams:
