Wind Generator Grid Tie Inverter
Grid-Tied Wind Generators, a promising clean and renewable energy, requires grid connection to convert and deliver
The grid-connected inverter is a key device for connecting wind turbines to the grid, converting DC power into AC power and running synchronously with the grid. Voltage control: Adjust the output voltage of the wind turbine to the grid voltage. Frequency control: Adjust the output frequency of the wind turbine to the grid frequency.
There has been a lot of discussion about using grid tie inverters (GTIs) with wind turbines to connect to the grid. Here we go trying to do our best to answer some basic questions about GTIs, their use with wind turbines, and to summarize trends we see emerging.
A grid-tie inverter converts direct current (DC) into an alternating current (AC) suitable for injecting into an electrical power grid, at the same voltage and frequency of that power grid. Grid-tie inverters are used between local electrical power generators: solar panel, wind turbine, hydro-electric, and the grid.
Grid-connected inverters for wind systems are frequently sold with the wind turbine. Manufacturers specify the grid-tied inverters for their wind turbine because every turbine has a different output voltage range. One turbine may produce AC that ranges from 0 to 300 volts. Another may produce wild AC from 0 to 200 volts.
