Composition and work principle of photovoltaic water pump system

Abstract

The invention discloses a composition and work principle of a photovoltaic water pump system, and the system comprises a solar cell photovoltaic array, a DC chopper, a frequency converter, a water pump, and a water storage device. The solar cell photovoltaic array is electrically connected with the DC chopper, and the DC chopper is electrically connected with the frequency converter. The frequencyconverter is electrically connected with a motor and the water pump, and the water inlet of the water pump is communicated with a water storage device through a water pipe. The solar cell photovoltaic array is electrically connected with an ASTPM module through a winding group, and the ASTPM module is in bidirectional connection with a central processor. The invention relates to the technical field of photovoltaic water pumps. The system causes no pollution, needs little maintenance, does not consume other resources, prevents the natural environment and human behaviors from causing the severer ecological environment, greatly improves the ecological environment, can prevent the land deterioration and desertification, and guarantees the good production and the life of the people.

Description

technical field [0001] The invention relates to the technical field of photovoltaic water pumps, in particular to the composition and working principle of a photovoltaic water pump system. 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 fo...
