In the modern world, special attention is paid to the improvement of pumping stations due to the increased requirements for the uninterrupted supply of fields with water and the development of new arrays, the task is to increase the power of power equipment and the height of the water rise, to improve its design. Most drives of pumping units of machine irrigation systems are built on the basis of an unregulated AC electric drive. This is often the main reason hindering the implementation of the required water supply schedule, optimizing the operating modes of pumping stations (including cascades) according to control criteria, reducing accidents, and increasing their reliability. At the same time, as studies conducted around the world show, the development of electric drives for machine irrigation remains promising. In this regard, an important task is the development of scientifically based technical solutions that ensure the reliable operation of pumping stations and pumping units. |
