Detailed Solution
Download Solution PDFGrid-connected wind turbine
- In this grid-connected wind power generation system, the wind turbine operates at a variable speed, so the alternator sends out a variable-frequency alternating current, which is converted by a rectifier-inverter device to obtain a constant-frequency alternating current output, which is then connected in parallel with the power grid.
- The primary drawback of using an induction generator in a grid-connected wind turbine is that it requires external reactive power from the grid to maintain its operation.
- This means the induction generator doesn't just provide active power to the grid; it also draws reactive power, which is needed to create the magnetic field essential for its operation.
- The grid's ability to supply reactive power can affect its overall stability, particularly in weak grids.
