Abstract

The paper presents the authors' results in documenting, designing and experimenting with a mobile energy subsystem of an irrigation system (SEMSI). The mobile energy subsystem was designed to operate with non-polluting energy (solar and wind energy). The subsystem is designed to work with a small water distribution system, a sprinkler. The subsystem is intended for irrigation in areas that do not have access to electricity but have access to water resources. In order to be able to create such an energy subsystem with the highest possible performance, it is necessary to document in several directions: similar achievements in the field (mobile energy subsystems on non-polluting energy resources), theoretical and practical calculations for the design of such systems, validation of the targeted qualities of these subsystems. For the above reasons, this paper includes some of the basic principles of irrigation and the main irrigation procedures (SEMSI is designed to serve several types of irrigation systems). After presenting the types of irrigation, the latest achievements in the field are presented. Then, some theoretical principles of designing irrigation systems are presented. Next, experimental methods for verifying, studying and validating irrigation systems are presented.

Abstract in Romanian

Lucrarea prezinta rezultate obtinute de autori in procesul de documentare, proiectare si experimentare a unui subsistem energetic mobil al unui sistem de irigatii (SEMSI). Subsistemul energetic mobil a fost conceput sa functioneze cu energie nepoluanta (energie solara si energie eoliana). Subsistemul este conceput sa lucreze cu un sistem de distribuire a apei de mici dimensiuni, un aspersor. Subsistemul este destinat irigatiilor in zone care nu au acces la energie electrica, dar, evident, au acces la resurse de apa. Pentru a putea realiza un astfel de subsistem energetic cu performante cat mai inalte, este necesara documentarea pe mai multe directii: realizarile similare in domeniu (subsisteme energetice mobile pe resurse energetice nepoluante), calculul teoretic si practic pentru proiectarea unor astfel de sisteme, validarea calitatilor vizate ale acestor subsisteme. Pentru motivele de mai sus, prezenta lucrare include cateva dintre principiile de baza ale irigatiei si procedeele principale de irigatie (SEMSI este proiectat sa deserveasca mai multe tipuri de sisteme de irigatie). Dupa prezentarea tipurilor de irigatie, se expun cele mai noi realizari in domeniu. Apoi se expun cateva principii teoreticeale proiectarii unor sisteme de irigatie. In continuare se expun si metode experimentale de verificare, studiu si validare a sistemelor de irigatii.
