Simulink based model of electric drive for throttle valve in pumping application

Centrifugal pump systems are one of the dominant parts in water distribution systems, irrigation networks, oil and chemical industries. Simulation of an electric drive system for throttling purposes in centrifugal pumps is proposed. Specific electric drive model is developed to provide all necessary possibilities for simulation. The model consists of several main components: DC motor, gear box, H-bridge, control system, different sensors and measuring equipment. To validate the developed model, a series of simulations were conducted. The simulation shows that the designed model is accurate and easy to tune. The proposed model of the electric drive for throttling application can be used as a tool for validating different control modes of valves in the centrifugal pump system.
