Wind energy plant operating method, involves dynamically changing electrical active power during exceeding main frequency threshold value by specific hertz depending on current main frequency in accordance with specific relationship

摘要

The method involves connecting an electrical generator with a power line for delivering electrical active power to a main connection point. The power line operates in a preset main frequency band limited by lower and upper main frequencies in a trouble-free condition. The active power is controlled depending on a current main frequency during exceeding a main frequency threshold value. The active power is dynamically changed during exceeding the main frequency threshold value by 50.2 hertz depending on the current main frequency in accordance with a specific relationship. An independent claim is also included for a wind energy plant comprising an electrical generator that is driven by a rotor.
