Photovoltaic pump system and design method

Abstract

The invention discloses a photovoltaic pump system and a design method. The photovoltaic pump system comprises a solar cell module, an inverter, a grid-connected batch meter, a frequency converter, anelectric tower and a water pump. The solar cell module is connected with the inverter in series through a wire. The inverter is electrically connected with the grid-connected batch meter through a wire. The grid-connected batch meter is electrically connected with the frequency converter through a wire. The frequency converter is electrically connected with the electric tower and the water pump through wires. The water pump is arranged in a water storage tank and communicates with a sprayer head arranged at the upper end of the water storage tank through a pipeline. Plants are arranged at thelateral end of the sprayer head. The photovoltaic pump system and the design method have the advantages of being free of pollution, not needing much repairing, not consuming other energies and the like, avoid the problem that the ecological environment gets worse and worse due to the influences of the natural environment and man-made sabotage, prevent great waste of resources, greatly improve theecological environment, and better guarantee the good life of people.

Description

technical field [0001] The invention relates to the technical field of photovoltaic water pumps, in particular to a photovoltaic water pump system and a design method. Background technique [0002] Photovoltaic water pumps are mostly composed of energy system, control system, pump system and connecting pipelines. The energy system is composed of solar panel components or batteries. Control, frequency conversion or inverter control, the pump system is mainly composed of pump body and motor. [0003] Photovoltaic water pump technology involves many disciplines. From the perspective of system composition, it is different from the conventional "power supply + water pump", but is a combination of disciplines such as optics, mechanics, electricity, power electronics, computer technology, and multi-machine group control technology. In general, it has reached the level of mass industrial production at present, and its technical level is comparable to that of foreign developed count...

Problems solved by technology

[0004] Most of the Northwest is my country's remote areas and areas inhabited by ethnic minorities. Due to poor natural conditions and historical inequality between the Han and ethnic minorities, the social development of the Northwest has always lagged behind that of the East. The primary problem in the poor areas of the Northwest is As for the water problem, in some severely arid areas in Northwest China, even the problem of drinking water has not been completely solved. The degree of poverty can be imagined. Thirty percent of the usable grassland area has not been used due to the lack of drinking water for humans and animals. The influence of the natural environment and man-made destruction have led to an increasingly serious ecological environment, resulting in a great waste of resources, which has greatly affected people's good production and life.
