A method for operating a wind farm having a string (S1-S3) of wind turbines (100-100c) which are electrically connectable with each other and a grid (510, 550) is disclosed. Each wind turbine includes a rotor (106) with rotor blades (108), a power conversi...

A SCADA system (14) includes a main switching hub (42) and a backup switching hub (44) that relay transmission data between a wind turbine generator (12) and terminals provided in another SCADA system (16) and client terminals (66), and a network switch (4...

The wind energy system (2) has wind-power plants (6) that are electrically connected by a power cable (8). A monitoring device (18) is provided for monitoring the wind energy system. A control device (20) is provided for setting electricity generation refe...

An electric-power-generation level predicting apparatus 1 includes a memory unit 20 that stores, as past data relating to a past electric power generation level of an electric power generator, past data containing information at multiple time points in eac...

The power plant has a rotor, with at least one rotor blade (406), coupled directly or indirectly to an electrical generator and an electrical system with different system units (400) incorporating electronic, electrical, electromagnetic and/or sensor compo...

Power delivered from the generator to the grid is regulated or adjusted as a function of grid frequency.
