    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.

    摘要: The present invention provides an apparatus for the controlled rotation of a nacelle of a wind turbine, which includes a control device and n of yaw brakes. In standstill operation, the n yaw brakes are actuated to impart a standstill holding moment M1 for holding the nacelle, and the n yaw brakes impart a substantially equal first holding moment. In tracking operation, the n yaw brakes are actuated to impart a tracking holding moment, M2, which is lower than the standstill holding moment M1 (M1>M2). The control device, in tracking operation, actuates a number m of the n yaw brakes to generate substantially the same constant holding moment M3, where M1/n>M3>M2/n, and where the other (n−m) yaw brakes are actuated to generate substantially the same constant holding moment M4, where m*M3+(n−m)*M4˜=M2, and M1/n>M2/n>M4.

    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.
