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
