FIELD: electrical engineering.
SUBSTANCE: invention relates to operation of wind-driven power plant (100) or wind farm (112) with several wind-driven power plants (100) for electric power exchange between wind park and power supply network, wherein each wind-driven power plant (100) has one or more power supply devices (808, 810), and wind power plant (100) or wind park (112) are connected through network connection (118) to power supply network (120), and power is exchanged through network connection point (118), wherein one or more power supply devices (808, 810) operate as voltage generating units (808) and one or more power supply devices (808, 810) operate as current-generating units (810), wherein, in particular, it is provided that voltage generating units (808) and current generating units (810) operate to generate voltage or respectively generate current, also in trouble-free operating mode of power supply network (120).
EFFECT: provision for maintenance of a power supply network with wind parks at change of behavior of a power supply network.
