Refinery Telecontrol system
Introduction
The refinery telecontrol system is designed for monitoring and control of pipelines within refineries and between them. The system provides safe operation from a single control station.
Structure
The telecontrol system has three-level architecture.
Control Room Level:
- I/O servers with redundancy support;
- Operator and engineer workstations;
- Communication and office equipment.
PLC level:
- Programmed logic controller;
- Intrinsically-safe converters;
- Uninterrupted power supply system;
- Surge and lightning protection devices.
Field device level:
- Sensors, actuators and valves;
- Fire and security alarm and access control subsystem;
- Container house utility subsystem;
- Electrochemical protection devices.
Main Features
- Monitoring of major and auxiliary process equipment;
- Data processing and transmission to control software (SCADA) via industrial networks;
- Control commands processing and transmission to actuators and other field devices;
- Monitoring and control of fire protection and security systems;
- Remote configuration of operation modes via industrial networks;
- Data exchange via telecommunication channels;
- HMI and process visualization;
- Process data archiving with historical data access capability.
The telecontrol system has a distributed architecture, consisting of operation control center and remote control stations, connected via telecommunication channels.
Benefits
- Flexibility
The system is designed to ensure scalability in hardware and functionality.
- Functionality
The telecontrol system components provide for additional operation modes (simulation, testing, masking) and other features, such as unauthorized access protection and event logging to monitor personnel actions.
- Compatibility
The system provides better integration with third party systems.
