Patent number: 8930035Abstract: A process for simultaneously providing capacity sale services (e.g. frequency regulation or voltage regulation), energy sale services (energy transfer from off-peak hours to peak hours), and stabilization services of a renewable plant may be provided. The process includes determining the values of energy quantity to be produced by the plant during a near future time interval. The process may also include introducing the values of energy quantity, in the control unit. Generating an hourly program of energy supply to be provided by the energy accumulator unit to the network may also be performed, depending on the values of energy to be produced, which stabilizes the power supplied by the plant to the network. Furthermore, the frequency and the voltage of the network may be regulated as well as transfers the energy between off-peak hours and peak hours, or from hours with saturation of the network to hours without saturation.Type: GrantFiled: June 29, 2011Date of Patent: January 6, 2015Assignee: Acciona Energia, S.A.Inventors: Luis Marroyo Palomo, Javier Marcos Álvarez, María Asunción Padros Razquin, Daniel Rabal Echeverria, David Cuesta Lerín, Iñigo Berazaluce Minondo, Christopher Walti

Patent number: 8541898Abstract: 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. In the electrical machines that form part of the wind power installation, generators and transformers, it is possible to change the impedance of the neutral closure introducing a plurality of active and passive elements. This limits the currents during the grid fault, thereby reducing the peak torque in the mechanical train of the wind turbines and allows guaranteeing compliance with the network connection requirements, as control of the active and reactive currents is maintained at all times.Type: GrantFiled: May 22, 2009Date of Patent: September 24, 2013Assignee: Ingeteam Power Technology, S.A.Inventors: Jorge Acedo Sánchez, Ainhoa Cárcar Mayor, Josu Elorriaga Llanos, Jesús Mayor Lusarreta, Susana Simón Segura, David Solé López, Mikel Zabaleta Maeztu, Jesús López Taberna, Luis Marroyo Palomo

Publication number: 20090316458Abstract: The invention presents a structure for the conversion of direct current electric power into alternating current electric power, characterised in that it is simple, highly efficient and minimises the problem of electromagnetic compatibility. The circuit includes, in its first preferred embodiment, six switching elements governed by a command unit, four switches forming an H-bridge (T1, T2, T3, T4) and two auxiliary switches (T5D, T6D), and two auxiliary diodes (Daux1 and Daux2).
