Example Embodiment
[0064] Example one:
[0065] The first embodiment provided by the present invention is a specific embodiment of a wind-fired-fired bundling base sending system for wind-power and thermal power-cutting strategy coordination simulation, such as figure 2 Shown is a schematic diagram of the power grid structure of a wind-fire bundling base in the northwest figure 2 It can be seen that the total wind power output of the wind-fire bundling base is 2621MW and the total thermal power output is 1550MW. The base sends power to the main grid through two 750kV and two 330kV lines.
[0066] The operation mode is arranged as the transmission power of the four-circuit line of the power transmission channel is 2800MW, and the fault is set as a three-phase short-circuit fault in one of the 750kV lines in 0.2s, and the 0.3s fault line trips and the fault is cleared. Failure of 750kV line.
[0067] Digital simulation shows that if only measures are taken to remove thermal power units and retain all w...
