| 20100213925 | ADVANCED REAL-TIME GRID MONITORING SYSTEM AND METHOD - This invention deals with an advanced Real-time Grid Monitoring System (RTGMS) suitable for both single-phase and three-phase electric power systems. This invention provides an essential signal processing block to be used as a part of complex systems either focused on supervising and diagnosing power systems or devoted to control power processors interacting with the grid. This invention is based on a new algorithm very suitable for real-time characterization of the grid variables under distorted and unbalanced grid conditions. The main characteristic of this invention is the usage of a frequency-locked loop, based on detecting the grid frequency, for synchronizing to the grid variables. It results in a very robust system response in relation to existing technique based on the phase-angle detection since grid frequency is much more stable variable than the grid voltage/current phase-angle, mainly during grid faults. Moreover, the algorithm supporting this invention is very efficient and can be implemented in regular industrial microprocessors. These features make the RTGMS object of this invention ideal to be applied in the control of distributed generation systems (DGS), flexible AC transmission systems (FACTS), power quality conditioners (PQC) and uninterruptible power supplies (UPS). In all these systems, the fast and precise real time detection of the voltage and/or current sequence components under grid fault conditions is a crucial matter. | 08-26-2010 |

| 20090163316 | PLANETARY TYPE GEAR UNIT COMPRISING A PLANET CARRIER WITH A PLANET BOGIE PLATE - A planetary type gear unit comprising a planet carrier with a planet bogie plate and at least one planet shaft, whereby on both sides of the bogie plate a planet wheel is mounted on the planet shaft by taper roller bearings, whereby the planet shaft is provided with an axially displaceable piece on each of its extremities forming an abutment which provides an axial support for the inner bearing rings of the taper roller bearings and with a tensioning elements by which the axially displaceable pieces can be displaced to one another for controlling the pre-tensioning on the taper roller bearings. | 06-25-2009 |
| 20090129924 | METHOD AND SYSTEM FOR OPERATING A WIND TURBINE - The present invention relates to a method and a system for operating a Wind Turbine (WTG), which WTG comprises a rotor comprising at least two blades, which blades are pitch regulated, where the rotor is connected to a shaft, which shaft is supported by bearings, and which shaft drives at least one generator, where the WTG uses a load regulation system for regulating the individual pitch of at least two blades. The object of the invention is to compensate for asymmetric load on the rotor in a wind turbine, a second object is to reduce wearing at shaft bearings in the wind turbine, and a third object is to increase the power production of a wind turbine. This can be achieved if the load regulation system measures the actual rotor load by at least one displacement sensor, which displacement sensor is measuring the bending of the main shaft, where the load regulation system based on the shaft bending regulates the individual pitch of the blades for compensating asymmetric load at the rotor. | 05-21-2009 |
