Problems solved by technology

Therefore, despite the great efforts of the respective manufacturers of the wind energy installation and the transmission, damages in the area of ​​the drive train always occur again, which can lead to damage to the wind energy installation
High strain also results in limited life of individual drive train components, necessitating component replacement on a case-by-case basis
The completion of such a replacement costs a lot of money and time and leads to undesired failures of the wind energy installation

Embodiment Construction

[0036] On the abscissa of the coordinate system shown in FIG. 1 , the temperature of the lubricant for the transmission of a wind power plant is plotted. In an example, the temperature is based on a measured value, which is measured in an oil pan of the transmission with a suitable temperature transmitter. The electrical power P provided by the wind energy installation is shown on the ordinate of the coordinate system. Based on the relationship plotted in the diagram, it is prescribed that each temperature T has a maximum power B Max , the temperature T is used to limit the desired power value P Soll . Also, the minimum value P of the power is plotted Min , which represents the lower limit for the temperature-independent power.

[0037] for maximum B Max The curve starts at the initial value P Frei At the minimum temperature on the left side of the diagram, this initial value accounts for the rated power P of the wind energy plant also plotted in the example Nenn about ...

Abstract

Disclosed is a method for starting a wind driven plant after operation stopping, wherein the wind driven plant is provided with a speed variator and an operation manager capable of controlling at least one operation variable B which is important for the speed variator of the wind device at an expected value BSoll, after the operation is stopped, the expected value BSoll is limited by a maximum value BMax preset according to measured temperature of the speed variator and / or speed variator lubricant.

Description

technical field [0001] The invention relates to a method for starting a wind energy installation after an outage, as well as a wind energy installation capable of carrying out the method. Background technique [0002] A wind energy installation has a drive train for transmitting the torque of a rotor of the wind energy installation driven by the wind to a generator providing electrical energy. In the most common configuration, the generator operates at a speed significantly higher than the rotational speed of the rotor, thus requiring a reduction transmission in the drive train. Such transmissions are usually realized with two or three stages and have several transmissions meshing with one another. All components of such a drive train are subject to high mechanical strains, the gearing of the transmission in particular being severely strained by the high torque of the rotor. Therefore, despite the great efforts of the respective manufacturers of the wind energy installatio...
