摘要： The invention relates to a wind power plant having a main controller (20). A set of condition parameters is fed to the main controller (20). The main controller (20) determines settings for the operation of the wind power plant (10) from the condition parameters. According to the invention, a minimal controller (27) and a monitoring module (28) are further provided. The minimal controller (27) determines a setting for the pitch angle and/or pitch speed from a subset of the condition parameters. In the event of an error in the processing of the main controller (20), the monitoring module (28) transfers the control over the wind power plant (10) to the minimal controller (27). The invention further relates to a method for operating such a wind power plant. The wind power plant (10) can be shut down in a controlled manner by means of the minimal controller (27) according to the invention if an error occurs in the main controller (20).
