According to one aspect of the teachings herein, various feeder connection arrangements and architectures are disclosed, for collecting electricity from wind turbines in an offshore collection grid that operates at a fixed low frequency, e.g., at one third...

The method involves operating an inner park network (16) of an electric circuit (10) with an operating voltage in a normal operation. Electrical wind energy system generators (13), which are driven by wind energy systems (11), are coupled with the network ...

A voltage control system for a wind turbine generator 110 is disclosed. The system includes a reactive power regulator 240 configured to control reactive power production by the wind turbine generator by adjusting a voltage setpoint for the generator. The ...

It is described a method for determining a limit value of a wind turbine reference operational variable, the wind turbine being connected to a connection node to which a utility grid is connected, the method comprising: obtaining a first input signal indic...

A wind turbine generator control system includes relatively fast regulation of voltage (110) near the individual generators with relatively slower overall reactive power regulation at a substation or wind farm level (150). The setpoint of the relatively fa...

The arrangement has at least two generators (1) driven by wind rotors that generate electrical energy for feeding into an electrical supply network. The generators have their generator phase outputs (R,S,T) connected in parallel to coupling points (KR,KS,K...
