Resumen
turbines 100 in a wind farm 200 are disclosed. In particular, a wind
farm 200 can include first and second doubly fed induction generator
120 wind turbine systems. The rotational rotor speed of the first wind
turbine system 100 can be regulated at reduced wind speeds based at
least in part on data indicative of rotor voltage to increase power
output of a doubly fed induction generator 120. The rotor speed can be
regulated such that the rotor voltage does not exceed a voltage
threshold. The power output of the first wind turbine system 100 can
be further increased by reducing its reactive power output. The
reduced reactive power output of the first wind turbine system 100 can
be compensated for by an increased reactive power output of the
second wind turbine system 100.

threshold. The power output of the first wind turbine system 100 can
be further increased by reducing its reactive power output. The
reduced reactive power output of the first wind turbine system 100 can
be compensated for by an increased reactive power output of the
second wind turbine system 100.

The present disclosure is directed to a system and method for securing a lightning protection cable (e.g. a conductor) of a
Resumen
lightning protection system within a wind turbine rotor blade. The lightning protection system includes a plurality of lightning
receptors configured along either or both of the pressure or suction sides of the rotor blade. The lightning receptors are connected
via the conductor so as to form a conductive circuit. Further, a cover assembly defining a passageway therethrough is configured
to receive at least a portion of the conductor along a length thereof. Thus, the cover assembly can be secured to an inner surface
of the internal cavity so as to maintain a location of the conductor. Accordingly, the conductor is free to move within the cover
assembly since the wire is not directly attached to the rotor blade.

TRAILING EDGE JETS ON WIND TURBINE BLADE FOR NOISE REDUCTION
Nº publicación US2016177922A1 23/06/2016
SIEMENS AG [DE]
Solicitantes
One or more air nozzles (31) create respective air jets (34) angled radially from a blunt trailing edge (22) of a wind turbine blade
Resumen
(20A-G). The jets create and maintain a radially flowing airstream (36) along the trailing edge that extinguishes vortex shedding
(28). This reduces drag and noise, thus allowing blades to have an extensive blunt trailing edge, which increases resistance to
buckling, thus enabling longer blades. The jets may be supplied by airflow from an air intake in a blade chamber (44), or a ram air
intake (40), or a compressor (54). Each nozzle may be individually metered (60) and/or individually or group valved (58) to
provide a particular airflow to each nozzle relative to the other nozzles. Overall airflow to the nozzles may be modulated
responsive to ambient conditions, and may be further cyclically modulated responsive to an azimuth of the blade

Systems and methods 300 for increasing the power output of wind
Resumen
turbines 100 in a wind farm 200 are disclosed. In particular, a wind
farm 200 can include first and second doubly fed induction generator
120 wind turbine systems. The rotational rotor speed of the first wind
turbine system 100 can be regulated at reduced wind speeds based at
least in part on data indicative of rotor voltage to increase power
output of a doubly fed induction generator 120. The rotor speed can be
regulated such that the rotor voltage does not exceed a voltage
threshold. The power output of the first wind turbine system 100 can
be further increased by reducing its reactive power output. The
reduced reactive power output of the first wind turbine system 100 can
be compensated for by an increased reactive power output of the
second wind turbine system 100.
