This means that the wind turbine array connection can be understood as two parts, and both parts are synchronized.
The first step is for the generator set of the wind turbine to meet the start-up requirements, start the machine to produce electric power, and connect it to the 3.5KV power grid at inside the wind farm.
p>The second step is to merge with the national grid. Wind farms are usually equipped with booster stations, and the output power is converted from 3.5KV to 110KV (or 220KV) and injected into the national grid.
In order to send electricity, small wind power plants must be connected to the grid, and the energy from the wind turbine is sent through the grid. If the wind turbine's energy is only for your own use, you should also consider sending energy back to the grid when there is no wind. If not, how will you use the energywhen there is no wind? So we still need to connect to the grid and get electricity from the grid. Of course, if wind power generation is only for your own use and you use grid power when there is no wind, this doesn't matter and wind power generation Wind energy does not need to be connected to the grid.
