Control en lazo cerrado de las electroválvulas Rotork para la succión y descargue del bombeo en la Estación Poliducto Osayacu

Abstract

This project is focused on the monitoring and control in closed loop of RotorK actuators located in the OSAYACU station belonging to the Shushufindi-Quito Poliduct of the Public Hydrocarbons Company of Ecuador. Where the actuators fulfill the function of notifying and controlling the increase in pressure in PSI from when the hydrocarbon enters the station until it leaves. At present, the control, monitoring and maintenance of the actuators is manually assisted by the maintenance personnel producing downtime or stopping the pumping when there is a failure. The implementation of this project aims to better control this type of setbacks. The project consists of assigning to each actuator a ModBus network ID that allows communication between the actuators and the master PC through a link bridge that is the Schneider Gateway. Each actuator has an independent address that is entered through the remote control within the Modbus configuration of the actuator. Once the address is assigned, the implementation of the ModBus master / slave network between the PC and the actuators is carried out. Where, when taking knowledge of the ModBus data records that we can obtain and control that can be carried out, the Project is carried out. With the design carried out, the respective functional tests are carried out that will determine the implementation of the project within the main HMI of the Station, this project will provide the company with a greater response time, control and assistance of the actuators.
