Methods of eliminating hydraulic shocks and variations in fluid head in the pipeline by properlyforming the transients of the start-up and shut-down of the electric drive of a pump assembly aresubstantiated. By representing the long pipeline as a dynamic object, it is possible to determineoptimum parameters for controlling the system electric drive-pump-pipeline in the case of' finitecontrol of the fluid head. Recommendations are given regarding the rate of the pump start-up andshut-down depending on the condition and parameters of the main.
