6.2 Reactive Power Control
With active power output, it must be possible to operate the generating plant in
any operating point with at least a reactive power output corresponding to a
active factor at the network connection point of
• cos ϕ = 0.8 underexcited to 0.8 overexcited
• (VDE-AR-N 4105,CEI 0-21 cos ϕ = 0.9 underexcited to 0.9 overexcited)
Values deviating from the above must be agreed upon by contract. With active
power output, either a fixed target value for reactive power provision or a target
value variably adjustable by remote control (or other control technologies) will
be specified by the network operator in the transfer station.
The setting value is either：
