Dual impeller closed type loop hydraulic transmission control ocean current energy power generation device and control method thereof

Abstract

The invention discloses a dual impeller closed type loop hydraulic transmission control ocean current energy power generation device and a control method thereof. An ocean current energy manner is adopted for driving a first impeller device and a second impeller device which are mounted in parallel, and the output ends of the first impeller device and the second impeller device are connected withcorresponding electric generators through a pump end spindle, a variable hydraulic pump, a pump variable mechanism, an energy accumulator, a variable hydraulic motor and a motor end spindle, the variable hydraulic pump, the variable hydraulic motor and the energy accumulator form a closed type system, and are connected with a closed loop control system, the closed loop control system is used for receiving the rotating speed of the pump end spindle, the closed loop control system is connected with an ocean current energy speed measuring impeller device and used for receiving an ocean current energy flow speed signal, and through control, displacements of the variable hydraulic pump and the variable hydraulic motor are adjusted. The inexhaustible ocean current energy is used for power generation, and through the off-network running mode, continuous energy supply is provided for remote island and remote water area power supply, underwater power equipment like an underwater vehicle and thelike.

Description

technical field [0001] The invention belongs to the technical field of power generation, and in particular relates to a double-impeller closed circuit hydraulic transmission and control sea current energy power generation device and a control method thereof. Background technique [0002] Ocean current energy is the kinetic energy of seawater flow, mainly referring to the relatively stable flow in submarine channels and straits and the energy generated by regular seawater flow caused by tides. It is another ocean energy that appears in the form of kinetic energy. It is an important part of renewable energy, with its high energy density and abundant reserves, which has attracted great attention from Europe, the United States, Britain, Japan and other countries. The field is still in its infancy. [0003] At present, the power supply of remote islands can only rely on diesel generators as the main power supply, and other wind power, photovoltaic, and wave power as auxiliary. ...

Problems solved by technology

Garrisoned military radars, underwater vehicles (UUV, ROV) and other devices consume abnormal power. my country has also proposed to build large power consumers such as deep-sea space stations and underwater charging piles. The existing power generation mode is far from meeting the demand for electricity.
