摘要： A method is employed for operating a wind turbine. Electrical energy is produced by means of a generator and is fed into an electrical power network. The electrical energy is fed to the secondary side of a transformer at a low voltage and is output on the primary side of the transformer at a higher voltage. The potential on the primary side of the transformer is undefined. In the method, a measured value of the voltage between the primary side of the transformer and the earth potential is first recorded. The measured value is compared with a predefined limit value. The electrical energy produced by the generator is changed if the measured value exceeds the limit value. A wind turbine is designed to carry out the method. Faults in the medium voltage network can be reacted to without an additional star point on the primary side of the transformer being required.

摘要： A method for operating a wind power plant having at least one rotor blade, the blade angle of which can be adjusted. The wind power plant is operated with a predefinable reduced energy output set point. To determine the potential output, at least one predefinable operating parameter of the wind power plant is measured and is applied to at least one stored characteristic curve for the reduced energy output set point. The actual energy output is determined and the loss in the output is formed from the difference between the potential output and the actual energy output.
