Wind Turbine Generator

Wind turbine generator is the conversion of wind energy into mechanical energy first and electric

energy afterwards，main components includes blades, generators and electrical。According to the

different rotation axis，Wind turbine consists of horizontal axis and vertical axis wind turbines two

types. System consists of off-grid and on-grid system.

I. On-Grid Wind Turbine Generator

On-Grid Wind Turbine Generator consists of wind turbine, on-grid system, dump load, on-grid

invertor. Wind through the fan into the AC power via the control system is converted into DC

electricity, through on-grid invertor converts DC power for the sine wave of the same frequency and

phase with the grid current, fed into the power grid.

◆Areas of application

○ On-Grid wind turbine power station

○ Government's image projects

○ Green power generation

○ Family of small power stations, self-contained self-sufficiency and achieve genuine green electricity

5 / 17

II. Off-Grid Wind Turbine Generator

Off-Grid Wind Turbine Generator consists of wind turbine, off-grid controller, battery, off-grid invertor,

power distribution system. Wind energy through the fan attached to the blade shaft-driven

generators produce unstable AC, using the controller rectifier to DC for battery charging. Battery

DC current through the fan off-grid inverters convert stable AC power to charge the load. As

excessive speed caused the DC voltage is too high, the controller starts to exceed the loads of

energy through the unloader offload.

◆Areas of application

○ Individual households power use，Plant power consumption，Energy conservation and reduction

○ Remote, power shortage areas

○ Aquaculture, pumps, water

○ Border, posts

○ Government's image projects
