FIELD: electrical equipment.
SUBSTANCE: field of application: electrical equipment. Method for electric power input into power supply network (1) by means of at least one wind-driven power plant (WP1) connected through network connection point (12) to power supply network, respectively, wherein power supply network (1) should operate with network frequency and each wind-driven power plant (WP1) has several wind-driven power plants (100), comprises steps of determining whether power supply network (1) is in operation mode, starting at least one wind-driven power plant (WP1) in cold start mode to generate electric power for feeding into power supply network (1). If power supply network (1) is not in operation mode, operation of at least one wind power station (WP1) in cold start operation mode, in which electric power is supplied to power supply network (1) and therefore power supply network (1) is operated, wherein in cold start mode and/or in operating mode during cold start-up, network frequency is set by inputting electrical power.
EFFECT: providing commissioning of a network which is in emergency shutdown state without using a large power plant having a synchronous generator directly connected to the network, which sets the network frequency.
