For a more detailed description of the reactive power procedure, see Section 14.4
Reactive power procedure.
In addition to the type of specified target value, the blue’Log also provides the option
of specifying the rate at which the Q control values change (gradient limitation) in
accordance with the grid operator's requirements (see Section 14.4.17 Gradient
limitation reactive power(Q) procedure). This gradient limitation merely relates to the Q
reactive power procedure
–
not to the cos
ϕ
reactive power procedure.
The reactive power system control loop function also provides the option of enabling
reactive power regulation (closed loop) (see Section 14.4.18 System control loop).
