Embodiment Construction
[0022] Such as figure 1 As shown, the wind power pumping system is composed of a wind power generation device 1, a controller 2 for real-time detection of on-site wind speed, and two water pumps M with different power 1 3. Water pump M 2 4. Unloading device R L 5 components, where the water pump M 1 The power of 3 is small, the water pump M 2 The power of 4 is relatively large, and the controller 2 controls the water pump M according to the on-site wind speed detected in real time 1 3. Water pump M 2 4. Unloading device R L 5 cut in and out.
[0023] Such as figure 2 and Figure 4 As shown, the wind power pumping control method is as follows;
[0024] 1) When V ≥ 4m / s, cut into the water pump M through the controller 1 , put it into use, and keep working when 4m / s≤V1 quit work;
[0025] 3) When V≥6m / s, cut into the water pump M through the controller 2 , and make the water pump M when 6m / s≤V2 Keep working, when V2 Quit work, pump M 1 cut in;
[0026] 4) When V≥...
