摘　　要：针对目前市电灌溉系统存在的依赖电网和灵活性较差问题,本文设计了一种适用于校园绿地的智能化光伏提水灌溉系统,主要包括太阳能光伏发电模块、提水及蓄水系统、灌溉设备和半自动控制系统等模块。以济南市齐鲁工业大学校园绿地为例,考察了制备光伏提水样机的技术可行性、经济可行性及节能减排潜力。实验结果表明,100 W的光伏提水灌溉样机可连续7 h均匀灌溉42 m^2左右的校园绿地,每年可节省电力130 kWh,每年可节约标准煤约52.5 kg,减排二氧化碳约103 kg。因光伏提水灌溉系统的初始投资较高,前6年的总成本高于传统市电提水灌溉系统,但运行7年后其经济效益逐渐显著,总成本低于市电提水灌溉系统。该光伏提水灌溉系统对建设节约型校园和提高大学生的节能减排意识具有重要意义。To solve the dependence on power grid and poor flexibility encountered by municipal power irrigation system,an intelligent photovoltaic water pumping irrigation system was designed for campus landscape,which was mainly composed of solar power generation module,water pumping and storage system,irrigation equipment and semi-automatic control system.Taking the campus landscape of Qilu University of Technology in Jinan City as an example,the technical feasibility,economic feasibility,energy saving and emission reduction potential of the fabricated photovoltaic water pumping prototype were investigated.The experimental results indicated that,one set of 100W photovoltaic water pumping irrigation prototype could continuously and uniformly irrigate about 42 m^2 of campus landscape for 7 hours.The prototype could save 130 kWh of electricity every year,which saved 52.5 kg of standard coal and reduced 103 kg of carbon dioxide emissions.Due to the relatively high initial investment,the total cost of the photovoltaic water pumping irrigation system was higher than that of the traditional grid power pumping irrigation system.However,its economic benefit is gradually significant after 7 years of operation with total cost much lower than that of grid power pumping irrigation system.The photovoltaic water pumping irrigation system is of great significance for building a conservation-oriented campus and improving college studentsawareness of energy saving and emission reduction.
