The system comprises a photovoltaic power generation system, an intelligent control system, an ultrahigh-lift pumping system and a pipeline system, wherein the photovoltaic power generation system is electrically connected with the intelligent control system; the intelligent control system is in communication connection with the ultrahigh-lift pumping system; and the ultrahigh-lift pumping system is fixedly connected with the pipeline system. The high-altitude ultrahigh-lift high-power solar photovoltaic water lifting technology and system are suitable for high-altitude areas with thin air, and the single-stage lift of a solar photovoltaic pump station can reach 1200m or above. The single-stage power of a water pump reaches 600kW in the environment with the altitude being 2500m or above. In the working process, the fluctuation of voltage and current is monitored inreal time, the working stability of the pump station is guaranteed, and the problem that a traditional photovoltaic pump station is difficult to achieve water delivery of an ultrahigh-lift pump station in a high-altitude area is successfully solved.

Description

technical field [0001] The invention belongs to the technical field of new energy development and utilization, and specifically relates to a high-altitude, ultra-high-lift, high-power solar photovoltaic water extraction technology and system. Background technique [0002] The plateau area in my country is high-lying, and the terrain is composed of a hilly plateau surface and a divided mountaintop surface, resulting in a large height difference between the water source and the farmland. In high altitude areas, the air is thin, the power infrastructure is weak, the topographical drop is large, and the power and head of the pumping station are large, which affects the heat dissipation of the electrical equipment of the pumping station built in the plateau area and affects the strength of the adiabatic medium. [0003] For the demand of ultra-high-lift pumping stations in high-altitude areas, traditional photovoltaic pumping stations adopt two methods: the first is to use the op...
