摘要： Controlling a converter of a wind turbine is disclosed. The converter is connected to a rotor of a doubly fed asynchronous generator in order to feed electrical energy into an electric network. The converter comprises a network-side inverter, a generator-side inverter, and a controller, which outputs target values for demanded reactive power to at least one of the inverters. A reactive power target signal is determined for the portion that the network-side inverter contributes to the demanded reactive power QT, a slip signal is determined from the frequency of the network and the rotational speed of the generator, a gain value is calculated according to the slip signal, and the gain value is modified according to the reactive power target signal for the network-side inverter. The distribution of the reactive power between the two inverters is thus optimized over a wide operating range, not only at individual predetermined operating points.

摘要： A method for packaging a large component into a protective case, which has a first and second reclosable access and a plurality of protective-case parts, wherein the large component has an access opening, comprising the following steps: providing prefabricated protective-case parts; attaching the protective-case parts to the large component; welding the transitions between the protective-case parts; shrinking the protective case; and arranging the first reclosable access in the protective case over the access opening. The packaging process is significantly accelerated compared to the known methods due to the prefabrication of the protective-case parts before the start of the method. Furthermore, the prefabrication provides the advantage that the prefabricated parts can be produced in series. As a result, the protective-case parts for several large components of the same type can be produced or purchased more cheaply.

摘要： The invention relates to a mobile rotary drive for a wind rotor of a wind power plant having a frame comprising a drive wheel for driving a segment of a rotor shaft of the wind power plant and a drive set which drives the drive wheel in rotation as a drive pinion, wherein the drive wheel is a friction wheel and interacts with a pressing device in such a way that the pressing device generates a force which presses the friction wheel onto the segment with the result that the friction wheel can apply a drive torque to the segment through friction, wherein a torque support for supporting an opposing torque to the drive torque generated by the friction wheel is also provided. Thanks to the friction wheel drive, there is no need for specific pre-equipping of the wind power plant. The invention makes available a mobile rotary drive which can be transported from one wind power plant to another.

摘要： Operating a wind farm in which the power generated by the wind energy installations is fed to a power supply system via a system internal to the wind farm and via a substation is disclosed. The farm director of the wind farm can ascertain a standard target voltage value and transmit it to the control units of the individual wind energy installations on the wind farm, which can use an overall factor to regulate the reactive power generated by a wind energy installation. The overall factor can be calculated from the difference between the actual voltage across the wind energy installation and the target voltage value, multiplied by a gain factor. On account of the impedance in the internal system of the wind farm, wind energy installations situated far away from the substation thus generate less reactive power than the wind energy installations which are situated close to the substation.
