Optimal structural design of residential cogeneration systems in consideration of their operating restrictions
Wakui, Tetsuya; Yokoyama, Ryohei - In: Energy 64 (2014) C, pp. 719-733
An optimal structural design model of a residential cogeneration system, known as combined heat and power, considering various kinds of operating restrictions is developed from the energy-saving viewpoint. As principal operating restrictions of cogeneration units, a constant power output...

Study of damage and repair of blades of a 300kW wind turbine
Marín, J.C.; Barroso, A.; París, F.; Cañas, J. - In: Energy 33 (2008) 7, pp. 1068-1083
The inspection of damages detected in some blades of 300kW wind turbines revealed that the nature of these damages was probably due to a fatigue mechanism. The causes that had originated the failure (superficial cracks, geometric concentrator, abrupt change of thickness) have been studied,...
