WIND PARK WITH ROBUST REACTIVE POWER ADJUSTMENT SYSTEM AND METHOD FOR THE OPERATION THEREOF

摘要

The invention relates to a wind park comprising at least two wind powersystems (1-5) which are connected to a main line (60) via two connecting lines(10), a linkage point (69) connecting the main line (60) to a power transfernetwork (9), and a park master (7) for reactive power adjustment, andcommunication lines (74) for transmitting control signals to the wind powersystems (1-5). According to the invention, reactive power adjustment system isembodied in the form of a distributed controller, comprising a main controller(73) on the park master (7), configured in such a way as to determine a set-point voltage (Usoll) and to produce a signal via the communication lines (74)in order to adjust an overall power coefficient of the power supplied to theenergy transmission network, and a sub-controller (184) on the wind energysystems (1-5) which is respectively configured in such a way as to calculatelocal reactive power setpoint values from the signal for the setpoint voltage,to detect the actual voltage given off by the wind power systems (1-5) and tocorrect the local reactive power setpoint values upon comparison with thesetpoint voltage (Usoll). The invention also relates to a method for operatingsaid wind park.
