【 摘 要 】

The article presents the method of the feasibility study of various methods of regulation on pumping installations of agricultural objects. It was found that the best results are observed in electric drives with frequency converters and valve cascade: here the total losses Qmin mode are only about 10% of the base value, which is explained by minimal losses in pipelines. There is no need to use valves at all. It is shown that with parametric control of the speed of an asynchronous electric drive with a phase-rotor, the loss in hydraulic elements (pump and network) has the same value as with frequency control (about 10% of the base value), but slip losses increase by 12%
