Problems solved by technology

Since it is impossible for wind power machinery to provide a wide variety of varieties to the market at present, it is impossible to meet the different needs of various environments, different transportation and installation conditions, and different head and flow water lifting systems, which limits the promotion of wind energy water lifting devices. application
[0004] After the advent of solar cells, photovoltaic water pumps appeared again, but due to the high price (the ratio of wind power to photovoltaic prices is about 1:4), the pumps of photovoltaic water pumps are specially manufactured, so it is also impossible for photovoltaic water pumps to provide various varieties to the market. , there is no large power photovoltaic water pump in actual use
At the same time, the pure use of wind or solar energy has limitations in resource distribution.
[0005] At present, there is no commercialized wind-solar complementary water-lifting system at home and abroad that can simultaneously utilize wind energy and solar energy.

Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing.

[0020] As shown in Figure 1, in this embodiment, a single fan or a solar battery array is used as a single power unit, and multiple power units are connected in parallel for power supply, and are composed of a programmable logic controller (PLC), a discharge device and a frequency converter. The intelligent controller is regulated and controlled, so that the submersible pump can maintain a good frequency conversion and speed regulation operation state, and realize variable flow water lifting. The intelligent controller performs program control and automatic management on the system operation, and has the function of maximum power tracking. The system does not need to be equipped with batteries when lifting water, with high efficiency and high reliability.

[0021] Key technology:

[0022] As can be seen from Figure 1, the key technology of this embodiment is to solve the ...

Abstract

The present invention relates to a several wind mills parallelly-connected type wind energy and optical energy complementary water elevation system. Said system includes the following several portions: wind-driven power generator unit, solar cell component, intelligent controller and submersible pump. The described intelligent controller can be used for controlling, managing and tracking said system.

Description

technical field [0001] The invention relates to a water-lifting system, in particular to a multi-fan parallel-connected wind-solar complementary water-lifting system. Background technique [0002] At present, the devices that use wind energy to lift water at home and abroad can be roughly divided into two categories: wind-driven water lifters that directly drive mechanical devices to lift water by wind wheels, and wind-powered water lifters that drive generators to generate electric energy by wind wheels, and then drive water pumps to lift water by electric motors. Power generation and water extraction system. [0003] The wind turbines of these two types of wind energy water lifting devices in the market all work independently by a single wind turbine. Since it is impossible for wind power machinery to provide a wide variety of varieties to the market at present, it is impossible to meet the different needs of various environments, different transportation and installation...
