Method for operating a wind energy plant park and wind energy plant park

摘要

The invention relates to a method for operating a wind energy park (1), in particular an offshore wind energy park, in the event of failure or malfunction of a voltage network (supply network) (10) supplying the wind energy park (1) or in the event of planned shutdown of transmission network components (11, 70, 71). . The invention further relates to a wind energy plant park (1) with at least two wind energy plants (20-24, 30-34) and an emergency power supply device (15, 16, 73-75 ''), comprising at least one emergency power supply unit (15, 16, 73-75 ') '). DOLLAR A The method according to the invention is characterized by the following method steps: DOLLAR A - detecting a malfunction or failure of the supply network (10) or a signal which is transmitted in preparation for the work on the transmission network components (11, 70, 71), DOLLAR A - Commissioning of an emergency power supply device (15, 16, 73-75 ''), the emergency power supply device (15, 16, 73-75 '') comprising an internal combustion engine (15, 74-74 ''), in particular a diesel engine, and DOLLAR A - controlled increase in the power output from the emergency power supply device (15, 16, 73-75 '') to the wind turbine park (1), in particular to transformers (25-29, 35-39) of the wind turbine park (1). DOLLAR A The wind turbine park (1) according to the invention is characterized in that a control device (73-73 '') for the controlled increase of the emergency power supply device (15, ...
