Patent number: 10161386Abstract: The present application is concerned with a flexible way of operating a wind farm with a plurality of degrading wind turbine components. According to the invention, maintenance scheduling and power production in the wind farm are handled concurrently in a single optimization step. Instead of a serial approach first scheduling maintenance activities and subsequently adapting the power production and/or wind turbine operation the two aspects are optimized together. The wind farm operation takes maintenance aspects into account by adapting life index or health status based on modeled mechanical and electrical stress. Accordingly, the wind farm owner may decide when and how much energy to produce accepting which level of stress to the turbine equipment.Type: GrantFiled: December 12, 2016Date of Patent: December 25, 2018Assignee: ABB Schweiz AGInventors: Adrian Timbus, Carsten Franke, Marija Zima

Patent number: 9331486Abstract: An exemplary method and apparatus for detecting islanding conditions of a distributed grid are disclosed, wherein transfer of power through a power electrical unit is controlled on the basis of a control reference. The apparatus includes a first stage and a second stage performing a respective portion of the method. The first stage injects a reactive component to the control reference, and, for at least one electrical quantity of the grid, determines a change in the quantity induced by the injected component, and determines, on the basis of the change in the electrical quantity, whether to move to the second stage of the method.Type: GrantFiled: November 5, 2012Date of Patent: May 3, 2016Assignee: ABB RESEARCH LTDInventors: Gerardo Escobar, Sami Pettersson, Leonardo-Augusto Serpa, Ngai-Man Ho, Antonio Coccia, Alexandre Oudalov, Adrian Timbus
