Application of mobile solar OFF-grid Generator in irrigation system — Case study

The paper presents multi-purpose mobile solar generator with modular structure, which provides power supply for both, single and three-phase consumers, in symmetrical, as well as unsymmetrical conditions. The additional feature of this device — pressure control in irrigation systems with three-phase centrifugal pump, is analyzed in details. The concept of irrigation systems based on the use of sprinklers is applied on a land plot with vegetables. Special attention is paid to the synthesis of PI pressure controller on the basis of a detailed mathematical models of the specific pumping system and mobile solar generator. The paper presents the results of measurements which were obtained in the real conditions on a land plot with irrigation system, with a critical review of the results obtained from the simulation model.
