Automated System of Frequency Control for Drive of Cascade Pump Station of Random Configuration

Abstract

The automated frequency control system of a cascade pump station has been developed. The mathematical modeling of a developed system has been carried out. The parameters of the control system transfer function have been calculated. The system simulation modeling without and with perturbation actions and with the use of the proportional-plus-integral control law has been implemented. The universal functional unit has been developed in the control program. This unit will allow controlling the pumps of a random number and with random power circuit. The use of this control system allows enhancing reliability of the water supply network, improving output characteristics of the system for the consumer, reducing the deterioration of pumping equipment and electric energy consumption.
