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 battery-free wind-solar complementary pumping device. Background technique [0002] Wind energy and solar energy are green renewable energy, known as the "future energy" for human survival, and have been widely developed and commercialized on a large scale, such as wind power, solar power, solar photovoltaic pumping, wind pumping, etc. However, the energy density of solar energy and wind energy is low, with the characteristics of instability and discontinuity, which makes the work efficiency of photovoltaic technology and wind power generation technology widely criticized. However, wind energy and solar energy have good complementarity. Some areas have poor wind resources in the summer half of the year, while the amount of solar radiation decreases in the winter half of the year; some areas have strong sunshine and weak wind during the day, and st...
