Introduction
Pipeline telecontrol system (PTS) is designed to control and
monitor main pipeline facilities including control and monitoring
stations, block valves, electrochemical protection stations, pig
launching and receiving chambers, feeder disconnectors and electric
power line circuit breakers.
Structure
PTS has three-level architecture.
Control room level:
- I/O servers with redundancy support;
- Operator and engineer workstations;
- Communication and office equipment.
PLC level:
- Programmable logic controller;
- Intrinsically-safe converters;
- Uninterrupted power supply system;
- Surge and lightning protection devices.
Filed device level:
- Sensors and actuators;
- Fire and security alarm and access control subsystem;
- Container house utility subsystem.
Main Features
- Collecting data from managed sites concerning processing
equipment and process parameters state, including data for leak
detection system work;
- Control action on controlled sites (shutoff valves control,
remote regulation setting);
- Availability and quality control of route power line
voltage;
- Security alarm support of sites (breaking of wells, control and
monitoring stations, cabinets);
- Visualization of transportation process;
- Information and alarm messages outputting in the case of normal
pipeline operation mode failure;
- Logging of process parameters trends;
- Equipment diagnostics;
- Reports generation.
Benefits
Support of event-driven data communication model for special
types of signals.
Unified approach to software and hardware elaboration (standard
line of cabinets, standard software) guarantees simple system
extension without additional spares.
Possibility of remote configuration of PLC software.
The system enables transferring equipment control right between
control units in accordance with specified priorities.
