Grid Tie Inverter
is core device of grid on wind turbine system.
It transforms power generated by the wind turbine
into alternating current and output to the commercial
electricity system.
Small wind turbine grid-connected power system
includes small wind turbine dump load, grid -connected
inverter, meter and power switchboard. When wind
speed reaches the cut-in-speed, the AC power from
the wind turbine will be fed in the utility grid
after rectifying and inverting. If the wind speed
is too large, part of the dump load will be connected
to the wind turbine to keep the constant power
to feed in the utility grid. |
