The field control system uses PLC which is widely used in the industrial control systems as controller. The main role of the PLC electrical control system is to achieve the start-stop of the fuel supply system, status monitoring of the system, alarms and closed-loop control of flow rate of the fuel. In order to complete the installation of the control system a fuel control cabinet was designed. The main components of the control system were installed in the fuel control cabinet; these components include PLC and its expansion modules buttons, lights, text display instrument, digital display instrument, relays, temperature acquisition instrumentation. Furthermore, in order to prevent electromagnetic interference, a VFD cabinet was designed to install VFD and other strong electrical components. VFD cabinet and fuel control cabinet were connected by a number of three-core cables, and the control signal from the PLC can be transmitted to VFD
