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≥...

Abstract

The invention discloses a water pumping control method for wind power generation. According to the method, a water pump M1 with lower power and a water pump M2 with higher power are adopted; a controller 2 is connected between a wind power generator and the water pumps M1 and M2 to detect an on-site wind speed V in real time, and an unloading device is connected through the controller. The water pump M1 is connected when V is greater than or equal to 4m/s, keeps working when V is greater than or equal to 4m/s and less than 6m/s, and exits when V is less than 4m/s; the water pump M2 is connected when V is greater than or equal to 6m/s, keeps working when V is greater than or equal to 6m/s and less than 8m/s, and exits when V is less than 6m/s and the water pump M1 is connected; the water pump M2 keeps working when V is great than or equal to 8m/s, and the water pump M1 is reconnected; the water pumps M1 and M2 keep working when V is greater than or equal to 8m/s and less than 10m/s; the water pump M2 keeps working and the water pump M1 exits when V is less than 8m/s; and the unloading device RL is connected when V is greater than or equal to 10m/s. The water pumping control method has the advantages of wide range of wind speed, high usage of wind power, capability of implementing continuous water pumping through the small water pump M1 and the large water pump M2, and high water pumping efficiency.

Description

technical field [0001] The invention relates to a method for controlling water pumping by wind power generation. Background technique [0002] The wind power pump is composed of a wind power device, a controller and one or more water pumps with the same power. When the wind force reaches level five or above, the controller drives the pump to pump water; when the wind speed is too high and the power generation efficiency is too high, the controller controls the water pump to stop working. Therefore, the available wind speed range of the existing wind power pumps is narrow, and the utilization rate of wind energy is not high. In addition, when the wind speed changes greatly, the water pump cannot work continuously, and the pumping efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a wind power pumping control method with high utilization rate of wind energy and high pumping efficiency. [0004] T...
