20110057445 | METHOD OF OPERATION OF A WIND TURBINE TO GUARANTEE PRIMARY OR SECONDARY REGULATION IN AN ELECTRIC GRID - The invention controls the network frequency via an active power reserve obtained by interacting in a coordinated manner with the speed regulation that acts on the power generated or on the pitch angle, to guarantee primary or secondary regulation across the whole range of wind speed. | 03-10-2011 |
20110057446 | WIND TURBINE OPERATION METHOD AND SYSTEM - The invention relates to wind turbines provided with doubly fed induction generators and with at least one power converter which is novel in that, under certain circumstances, it enables the turbine to operate as a full converter (FC) system, as a doubly fed (DFIG) system or as an asynchronous (AS) system, thereby increasing turbine availability. | 03-10-2011 |
20110140432 | CONTROL METHOD AND SYSTEM FOR A WIND POWER INSTALLATION IN CASE OF GRID FAULTS - The present invention relates to a method and system for controlling a wind power installation connected to an electrical power grid, in case of a fault in said grid. | 06-16-2011 |
20110156390 | METHOD FOR CONTROLLING A WIND TURBINE - The proposed invention describes an alternative for machines with at least one power unit ( | 06-30-2011 |
20110196543 | SYSTEM AND METHOD FOR POWER MANAGEMENT IN A PHOTOVOLTAIC INSTALLATION - The subject matter of the invention is the provision of a power-management system and method for photovoltaic installations connecting to the grid, which incorporates monitoring active and/or reactive power, account being taken at all times of grid requirements, in order to allow temporary demand arising in the grid to be addressed, thereby contributing to regulation of the grid and to the stability and quality thereof. | 08-11-2011 |
