Design and Implementation of a Series DC Water Pump Irrigation System Driven by Photovoltaics

Abstract: [Objective] Agricultural irrigation is an important link in agricultural production, and traditional agricultural irrigation methods often rely on oil-fired generator sets or wiring for electricity, which is not only energy consuming but also environmentally friendly. Therefore, studying a green and sustainable agricultural irrigation method has important practical significance. [Method] Photovoltaic power generation has the advantages of clean, renewable, and green environmental protection, making it an ideal energy source for agricultural irrigation. The author proposes a series DC water pump irrigation system based on photovoltaic drive, which achieves irrigation of high-altitude farmland through the series connection of 20 power units. [Result] 1) It is possible to achieve green and sustainable agricultural irrigation, reduce dependence on oil-fired power generation units or municipal electricity, reduce energy consumption, and reduce environmental pollution. 2) The use of series connection achieves maximum utilization of water pump performance and improves the irrigation efficiency of the system. 3) Real time monitoring of key components such as water pumps and photovoltaic panels has been achieved. When a drive unit malfunctions, the system can detect and suspend the operation of all units in a timely manner, ensuring the safe operation of the system. 4) Implemented remote control of the entire system’s start and stop with mobile phones, improving the system’s operational convenience and real-time performance. 5) Implemented monitoring and control of system status, ensuring stable operation of the system within the normal range of water pressure at all levels.
