| 摘要 |
<p>The invention relates to a method for controlling a wind farm (200) comprising a plurality of wind turbines (202) for feeding electrical power at a network connection point (PCC) (204) into an electrical AC voltage network (206). The method comprises feeding in a three-phase current at the network connection point (204), detecting a mains voltage (UN) at the network connection point, comparing the mains voltage (UN) detected at the network connection point (204) with at least one predetermined target value, determining target values for the wind turbines (202) depending on the performed comparison to comply with a stability criterion at the network connection point (204), transferring the specified target values to turbine control units (212) of the individual wind turbines (202), and generating electrical current (i'1, i'2, i'3) at each of the wind turbines (202) depending on the predetermined target values for jointly feeding in at the network connection point (204).</p> |
