dc.description.abstractThis paper deals with the behaviour at high pressure operation points of a hydraulic Power Take-Off (PTO) using a highly detailed model based on four double-acting hydraulic cylinders modelled by a port-based approach. The developed model takes advantage of the availability of basic hydraulic components which can be parameterized based on real ones, including most of the hydraulic losses. With the aim of optimizing the extraction of wave energy, this PTO is able to modify its restraining torque through the independent activation of the hydraulic cylinders located in the primary transmission and modifying some geometrical parameters related to their fixation points respecting to the axis torque. The ultimate objective of this PTO is to provide a wide range of torques that can be modulated by modifying the operating high pressure of the HP accumulator, the combination of the available areas of the double-acting hydraulic cylinder and the location of their fixation points with respect to the applied movement. This factor can help to improve the control of WEC based on activated bodies with the aim to optimize the extraction of wave energy. In this paper an extended simulation results at different operation points and input movements are presented.en
