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
