The working principle of the wind power hydraulic system is to convert wind energy into mechanical energy, and then convert the mechanical energy into electrical energy through hydraulic transmission.
When the wind turbine blades are driven by the wind to rotate, the mechanical energy of the rotation is converted into hydraulic energy through the hydraulic pump, and the hydraulic energy is stored in the hydraulic tank. Then, the hydraulic flow direction is controlled through the hydraulic valve, and the hydraulic energy is transferred to the hydraulic motor or hydraulic cylinder, which then drives the generator to rotate and generate electrical energy.
2. Composition of wind power hydraulic system
The main components of a wind power hydraulic system include:
Hydraulic pump: Responsible for converting mechanical energy into hydraulic energy and sending hydraulic oil into the system.
Hydraulic motor: converts hydraulic energy into mechanical energy to drive the generator to rotate.
Hydraulic valve: used to control the working status and parameters of the hydraulic system, including flow, pressure, direction, etc.
Hydraulic cylinder: Optional component used to control the adjustment of wind turbine blades to optimize the efficiency of capturing wind energy.
Hydraulic oil tank: stores hydraulic oil to ensure lubrication and cooling of the system.
Controller: used to monitor and control the working status of the hydraulic system to achieve automated control.
