The invention relates to a wind-solar complementary water lifting device free of a storage battery. The wind-solar complementary water lifting device comprises a solar photovoltaic battery array, a wind generator set, a wind-solar complementary controller and a direct-flow water lift pump. An input end of the wind-solar complementary controller is connected with an output end of the solar photovoltaic battery array, and another input end of the wind-solar complementary controller is connected with an output end of the wind generator set; an output end of the wind-solar complementary controller is connected with an input end of the direct-flow water lift pump, and the direct-flow water lift pump is arranged in a lower-level water reservoir of a water reservoir unit. The water reservoir unit comprises an upper-level water reservoir, and the direct-flow water lift pump is used for lifting water of the lower-level water reservoir and storing the water in the upper-level water reservoir. The wind-solar complementary water lifting device abandons a storage battery in conventional wind-solar complementary generation, solar energy and wind energy are directly used for lifting water after complementary to each other, energy storage is changed into water storage, the problem that conventional photovoltaic water lifting and wind water lifting are low in efficiency is solved, and the defect that an energy storage battery is high in composition cost, short in service life and difficult in maintenance and pollutes the environment and the like is overcome.
Description
Technical field [0001] The invention relates to the technical field of new energy development and utilization, in particular to a wind-solar complementary water pumping device without storage battery. Background technique [0002] Wind energy and solar energy are green and renewable energy, known as the "future energy" for human survival, and have been extensively developed and commercialized on a large scale, such as wind power, solar power, solar photovoltaic pumping, and wind pumping. However, solar energy and wind energy have low energy density and are characterized by instability and discontinuity, which makes the work efficiency of photovoltaic technology and wind power technology widely criticized. Wind energy and solar energy are complementary. In some areas, wind resources are scarce in the summer and solar radiation is reduced in the winter. In some areas, the sun is strong during the day and the wind is weak, and there is no light but the wind is strong at night. Ther...
