Abstract

Objective: In the present study, effective methods for managing energy consumption in pumping stations and pressurized irrigation systems have been examined.
 
Method: Energy consumption management methods have been examined in three general approaches: improving system operation methods, improving system operation methods and installing energy consumption management equipment, and improving pump startup methods.
 
Results: The results of the study show that from an economic perspective, the energy costs, repair and maintenance of a pumping system over its lifetime are up to 20 times its initial investment, and the use of energy management technologies, such as energy audits, will increase energy efficiency by 15 to 20 percent, operating the pump near the optimum operating point will reduce energy consumption by up to 35 percent, implementing automation systems in pumping stations will reduce energy consumption by up to 32 percent, and using variable speed pumps will reduce energy consumption in agricultural water pumping stations by up to 19 percent.
 
Conclusions: It is important to note that due to the wide range of factors involved in managing irrigation systems, it is necessary for farmers and operators to choose an appropriate and economical method for controlling energy consumption based on the existing conditions of the farm.
