1. WOWO/2014/124643 - DETECTING BLADE STRUCTURE ABNORMALITIES21.08.2014
F03D 11/00
PCT/DK2013/050038VESTAS WIND SYSTEMS A/SEHSANI, Saed
To identify abnormal behavior in a turbine blade, a failure detection system generates a "fingerprint" for each blade on a turbine. The fingerprint may be a grouping a dynamic, physical characteristics of the blade such as its mass, strain ratio, damping ratio, and the like. While the turbine is operating, the failure detection system receives updated sensor information that is used to determine the current characteristics of the blade. If the current characteristics deviate from the characteristics in the blade's fingerprint, the failure detection system may compare the characteristics of the blade that deviates from the fingerprint to characteristics of another blade on the turbine. If the current characteristics of the blade are different from the characteristics of the other blade, the failure detection system may change the operational mode of the turbine such as disconnecting the turbine from the utility grid or stopping the rotor.

9. WOWO/2014/124547 - ELECTROMECHANICAL CONTROL SYSTEM FOR A GROUP OF BIDIRECTIONAL FLUID TURBINES THAT GENERATE ELECTRICITY21.08.2014
F03D 11/02
PCT/CL2013/000055SERANI MOSTAZAL, JorgeSERANI MOSTAZAL, Jorge
The invention relates to the use of kinetic energy of fluids, particularly water and wind, for the production of electrical energy and consists of an electromechanical control system for bidirectional turbines. For many years, man has been efficiently harnessing the kinetic energy of water flowing on the Earth's surface, as well as the kinetic energy of wind. Flows of water are determined by climate, gravity and the topography of the land, for which unidirectional turbines have been developed that efficiently convert kinetic energy into electrical energy. Something similar occurs with wind and wind turbines, which, in large part, depend on the rotation of the earth and the temperature difference between the equator and the poles. Nonetheless, the generation of electrical energy from the kinetic energy of water and wind, given the enormous potential of both, could be made more efficient by using bidirectional turbines that allow the use of flows and back-flows, as well as allowing the use of horizontal turbines which do not feature in the design of current turbines. The present invention overcomes the unidirectionality restriction of current turbines, as well as allowing the possibility of operating with up to three types of turbines together and coupling two of same. The invention has three main components, namely: the mechanical component comprising a differential, an axle and two half-axles; the electromechanical component consisting of a gearbox and two starter motors; and an electric circuit, all of which combined improve the efficiency of wind and water turbines in the conversion of kinetic energy (water and air) into electrical energy.

10. WOWO/2014/125259 - LUBRICANT HEATING AND COOLING SYSTEM21.08.2014
F03D 11/00
PCT/GB2014/050390ROMAX TECHNOLOGY LIMITEDSCOTT, David
An apparatus for controlling a temperature of a lubricant for a drivetrain of a wind or water turbine includes a circuit for the lubricant (32) connected to the drivetrain (8); a heat exchanger (10) connected to the circuit for the lubricant (32), the circuit for heat exchange fluid (34) connected to the heat exchanger (10), and the circuit for heat exchange fluid further connected to a source of thermal energy and to a sink of thermal energy. A controller (36) regulates a flow of thermal energy between the lubricant and the heat exchange fluid via the heat exchanger (10). This means that when the turbine rotor (104) is being driven by wind or water and is generating electricity, thermal energy transferred to the lubricant can be dissipated via the heat exchanger (10) into the heat exchanger fluid. Similarly, when the turbine has not been generating electricity, or the turbine is operating under conditions where the lubricant temperature is low, thermal energy can be transferred into the lubricant from the heat exchange fluid via the heat exchanger (10).
