POWER CONTROL FOR A WIND PARK

摘要

The invention relates to a safe and economical method for controlling the power emitted by a wind park (1). Said wind park comprises wind energy plants (2) which are electrically interconnected by means of a wind park network (5) wherein a wind park control unit (13) transmits a wind park predetermined value to plant control units (12) which are respectively provided for controlling a wind energy plant (2). Said plant system control units (12) control the respectively associated wind energy plants (2) in such a manner that the system power PI transmitted by the respective wind energy plant (2) to the wind park network (5) is less than the maximum power Pmax, of the plant derived from the wind park predetermined value. As a result, all plant control units (12) obtain the same wind park predetermined value and each plant control unit (12) determines the maximum power of the plant Pmax, based on the wind park predetermined value and based on a measured plant power PI which corresponds to the power produced by the associated wind energy plant (2) and controls the respectively associated wind energy plant (2) such that the power of the plant PI is less than the maximum power of the plant Pmax.
