Intelligent vibration damping device for over-sea floating wind turbine platform

Abstract

The invention discloses an intelligent vibration damping device for an over-sea floating wind turbine platform. The intelligent vibration damping device comprises a control system, turbine actuating systems, self-floating turbine protecting devices and rigid connecting rods, wherein the turbine actuating system are positioned inside the self-floating turbine protecting devices and are rigidly connected with the floating platform by the rigid connecting rods; each turbine actuating system is in signal connection with the control system; the turbine actuating systems, the self-floating turbine protecting devices and the rigid connecting rods are equal in quantity. The control system is used for acquiring and analyzing oscillation signals of the floating platform, sending a control instruction and controlling the turbine actuating system which is required to act to work; a turbine rotates under water to generate a counter-acting force for inhibiting oscillation of the floating platform so as to realize the aim of damping the vibration of the floating platform. The intelligent vibration damping device is simple in structure, rapid in response, applicable to different types of floating platforms, wide in application range and high in practicability.

Description

technical field [0001] The invention relates to an intelligent damping device for an offshore floating wind turbine platform, belonging to the technical field of wind turbines. Background technique [0002] As an important way to utilize wind energy, wind power generation has developed rapidly in recent years. Offshore wind power has the advantages of high wind energy density, high annual utilization hours, close to the power load center, and does not occupy cultivated land. It is the main direction of future wind power development. With the continuous development of wind power utilization in deep water areas, the economy of fixed foundations will drop significantly, and floating support systems will replace them. [0003] The floating platform will move with multiple degrees of freedom as the waves are excited. These movements will affect the aerodynamic load of the wind turbine and aggravate the unsteady and nonlinear characteristics of the blade load. At present, many t...
