THE DETERMINATION OF ENERGY-SAVING PROPERTIES OF INTERACTIVE CONTROL IN PUMPS INSTALLATIONS

Interactive electromechanical automation multyaggregate pumping installations system reduces power consumption compared to common stabilize pressure systems. An interactive regulator output signal is formed as a result of comparing the values of technical parameters on the current and previous quantization steps. The direction of torque frequency change of controlled electric drive depends on the hydraulic resistance network at the previous quantization step. It was investigated the influence of hydraulic resistance of the system on the reaction of electromechanical system on the parallel and series connected units. The analytical expression of boundary resistance, by which the speed of controllable electrical drive remains constant has been obtained.
