Abrégé
A condition monitoring system and method for electrical power components, in particular a transformer. A partial discharge detector unit captures acoustic signals of the partial discharge by means of an A-sensor. A processing unit captures a frequency of the partial discharges detected by the A-type sensor and a histogram module determines a temporal profile of the frequency from the frequency signal and a time signal. An analysis unit monitors the temporal profile for a fall and/or rise, preferably by means of pattern recognition. A warning signal is triggered if an adjustable threshold is exceeded. An imminent failure of an electrical power component can therefore be detected in good time and warned of; the component can be automatically disconnected if appropriate.

A prediction model is fed with a current wind value of the first wind turbine, in order to predict a future time point at which the area swept by the rotor of the second wind turbine becomes partially overlapped by the wake of the first wind turbine. The second wind turbine reacts to the prediction in that a control signal is generated in order to alter the pitch angle of a rotor blade of the second wind turbine relative to the pitch angle of another rotor blade of the second wind turbine. The invention additionally relates to a control system suitable for executing the method. Implementation of the disclosed method by a control system can reduce the loading of the second wind turbine.

Statistical uncertainty is determined and the target value is then dynamically offset such that a corresponding buffer margin (security margin) is generated: large in the event of high uncertainty, low in the event of low uncertainty. Under consistent wind conditions, the security margin is significantly narrower, thus resulting in a larger target value.

Abrégé
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.

Abrégé
A method for determining an energy yield loss of a first wind turbine of a wind farm that includes a plurality of wind turbines. The first wind turbine is operated in a reduced energy yield mode that is outside an energy-optimized normal operating mode and a reduced energy yield of the first wind turbine is determined. At least one second wind turbine is selected according to a pre-determinable criterion. The energy yield of the at least one second wind turbine is determined and depending upon the energy yield of the at least one second wind turbine, an energy yield potential of the first wind turbine is determined. The difference between the energy yield potential of the first wind turbine and the determined reduced energy yield is formed.

Wind farm harmonic predictor and method for predicting harmonics

Inventeur(s)
Letas, Heinz-Hermann
Abrégé
A harmonic predictor for a wind farm comprising at least two wind turbines, each having a generator with a converter for generating electrical energy. The harmonic predictor determines the harmonic component expected from the wind farm in order to limit the harmonic component to a harmonic limit. The harmonic predictor comprises a calculation module, an iteration module and a summing module. The calculation module calculates a complex mean value over at least one period of the harmonic component of one of the wind turbines and determines a first equivalent vector therefrom. The iteration module successively connects the calculation module to at least one other of the wind turbines to form at least one second equivalent vector. The summing module sums the equivalent vectors to form a total vector and compares the total vector with the harmonic limit.

Abrégé
A wind turbine having a generator for generating electrical energy and a transformer is disclosed. The transformer is designed to receive electrical energy from the generator on a secondary side and to discharge said electrical energy again on a primary side at a higher voltage. The wind turbine also comprises a temperature monitoring means for the transformer. The voltage supply to the temperature monitoring means is fed from the primary side of the transformer. The temperature monitoring means is thereby independent of the control system of the wind turbine. The temperature monitoring means reduces the risk of the transformer overheating. A method for operating such a wind turbine is also disclosed.

Abrégé
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.

Abrégé
A method for operating a wind turbine (10). The wind turbine (10) is operated with variable rotational speed between predeterminable minimum and maximum rotational speeds. A characteristic variable (51) of an oscillation of the wind turbine (10) is detected. The wind turbine (10) includes a tower (14) and a rotor (13). An open-loop or closed-loop control device (36, 50) provides open-loop control or closed-loop control of the rotational speed of the rotor (13) between a minimum rotational speed and a maximum rotational speed during a power-supplying operation of the wind turbine. A sensor (40) detects a characteristic variable (51) of an oscillation of the wind turbine (10) and the minimum rotational speed is changed depending on the characteristic value (51) of the oscillation. The minimum rotational speed is altered depending on the characteristic variable (51) of the oscillation by the open-loop or closed-loop control device (36, 50).

A wind power plant tower having a multiplicity of tower segments which are arranged one on top of the other and enclose an interior tower space, and at least two system components from the group of a conductor, a lighting and a climbing device for operating personnel arranged in the tower inner space. Segments for the system components are structurally combined with a beam to form a separate supply module spanning a number of tower segments. The laborious assembly of the system components can thus be carried out at ground level, and only the supply module thus completed, which spans a number of segments, is then mounted in the tower. This obviates the need for a considerable amount of work in the form of hazardous working in the tower.

ref). Furthermore, additional regulation is provided, which has an input for an additional power and is designed to produce a rotation speed change signal therefrom, taking account of a rotator inertia moment, and to output this as an output signal, which is added to the nominal rotation speed signal via a logic element. Kinetic energy is taken from the wind rotor in a controlled manner by reducing the rotation speed and is converted by the generator to additional electrical energy. This allows primary regulation power to be made available deliberately by rotation speed variation, to be precise even in unsteady wind conditions.
