The present invention concerns a method of operating a wind park having a plurality of wind power installations. A wind power installation includes an electrical energy storage means associated with the wind power installation to store electrical energy which is consumed for starting up the wind power installation after stoppage and consumed for emergency shutdown of the wind power installation. In some embodiments, the wind power installation includes a control system to control taking of energy from the electrical energy storage means for an emergency shutdown procedure such that a sufficient emergency shutdown reserve is maintained in the electrical energy storage means to start a first wind power installation without consuming energy from a network.

Operating method for a wind park

A method of erecting a pylon, in particular a pylon of a wind power installation, which has a foundation with segment anchors, wherein connecting elements project beyond the top side of the foundation by a predetermined amount. A ring is leveled, aligned and fixed at the top side of the foundation. A gap produced by leveling, aligning and fixing of the ring is underlaid with a grouting material. The grouting material is set and a lower pylon segment is placed on the leveled, aligned and fixed ring and connected thereto.

Tower and foundation

A wind power installation is provided having a pylon, a pod mounted rotatably on the pylon, a generator arranged within the pod and having a rotor and a stator, and at least one fan in the region of the pod. The fan may be adapted to blow air out of a rear part of the pod, through an air gap between the stator and the rotor and into a front part of the pod. A seal structure may be positioned in the pod in such a way that an air flow that bypasses the air gap between the stator and the rotor is substantially prevented.

A rotor blade of a wind power installation in which the rotor blade, in particular in the central region of the rotor, the so-called main board, has a lift-drag ratio which in the region of about &#xb1;2&#xb0; from the optimum pitch angle has a lift-drag ratio value of more than 80%, preferably 90% and more of the maximum value of the lift-drag ratio.

Rotor blade for a wind turbine

Described is a rotor blade for a wind power installation having a rotor blade leading edge. A deposit sensor device is arranged in the region of the rotor blade leading edge. That deposit sensor device has a transmitter for the wireless transmission of signals by way of a transmission link and a receiver for receiving the signals wirelessly transmitted by way of the transmission link. Deposits on the surface can be detected in the region of the transmission link on the basis of the signals transmitted by way of the transmission link.

The present application is directed to a method and an apparatus for avoiding and/or reducing pollutant percentages in the exhaust gas of an internal combustion engine. Before fuel passes into the combustion chamber of the internal combustion engine, it is exposed to electromagnetic signals. The electromagnetic signals including at least two signals at two preset frequencies, and are above 20 kHz. The electromagnetic signals are delivered by way of a transmission member that is disposed in a fuel treatment unit, which has a fuel feed line to a fuel tank and a fuel discharge line to the internal combustion engine.

The invention concerns a wind power installation comprising a flight warning light arrangement. In accordance with the invention it is proposed that the flight warning light arrangement is switched on only when a vehicle or craft, preferably an aircraft, approaches the wind power installation to a predetermined spacing.

Wind turbine comprising approach lighting

The present disclosure relates to a method for operating a wind turbine with the steps: detection of the values of predetermined operating parameters by means of suitable sensors, detection of at least one predetermined initial condition, comparison of the detected values to stored values of the operating parameters. The disclosure further relates to a wind turbine for implementing the method. Therefore, the object of the present disclosure is, to be able to adapt the operation of a wind turbine to changes using a method of the type named above, such that when the detected parameter values deviate from the stored parameter values, as a function of the initial condition, either the stored parameter values are adapted to the detected parameter values or the operation of the wind turbine is influenced as a function of the detected parameter values. In this way, the disclosure is based on the knowledge that, from a pragmatic view, the formation of ice on a rotor blade is also a (temporary, meteorologically-related) change to the rotor blade shape. From this it follows that the formation of ice on the rotor blades always leads to a change of the aerodynamic profile and thus to a negative effect of the output of the wind turbine. However, deviations from this shape and thus deviations in the magnitude of the generated output also result just from manufacturing-dependent deviations of the rotor blades from the predetermined optimum shape and from gradual soiling of the rotor blades during operation.
