GE Energy OC 6000e* Distributed Control System
In today’s competitive production environment, process industries demand a totally integrated control and optimization solution that can increase productivity, reliability, and quality while minimizing cost. These customers are driven to search for solutions to improve their competitive edge and to enhance their return on investment. GE Energy’s OC 6000e* Distributed Control System is designed to meet these customers’ needs.
System Architecture Control system failure will likely result in the loss of production and equipment damage. This makes control system reliability an extremely important consideration when choosing a control system. The OC 6000e DCS has been engineered with special attention to diagnostic and redundancy features. The results are reduced downtime, improved system availability, enhanced control reliability, and uninterrupted system access.
OC 6000e DCS Typical Topology Network redundancy can be implemented on two levels, depending on whether you install single or dual media. During normal operation in a single ring, the redundant switch-hub will continue to operate without interruptions during a single network fault so there is no impact on network operation. In the event of two simultaneous faults, the network is divided into two isolated parts and continues to operate in this capacity.
World Class Products: Network based I/O (Ethernet) Support Field Bus Simple/DMR/TMR RTFN (Ring) Powerful CPU Compact cabinet Qualified hardware (Test) Safety cerifications Integrated GE controls • Mark Vle • Fanuc • 3500/3700/System 1 • Emap/Coalogic/CBO The control software supports powerful control applications through straightforward configuration of function blocks.
Alarm List I/O Module directly in the field close to operating devices, and then be connected to the OC 6000e network via the optic fiber or shielded twisted pair wire. This reduces field wiring runs and saves system installation expense. Hot-swap capability and comprehensive diagnostics expedite maintenance and reduce downtime. Replacement of I/O modules can be performed under power and will not interrupt the operation of other modules.
engineer, engineer, operator, and null. Each level has specific system operability access, with super engineer being the highest. User management allows add, delete, and modify for user accounts and passwords. Data Acquisition and Management The Operation Management subsystem provides a common interface for plant operators, engineers and maintenance personnel. The same HMI station presents each user class with critical information when and where it is needed.
A library of standard display elements, such as valves, pumps, and switches is supplied with the system. Alarming System and process alarms are essential to safe and efficient operation. The OC 6000e DCS has a flexible alarm-monitoring capability and is specifically designed to attract the operator’s attention during operation upset and allows operators a clear view of unit operating condition. Alarms can be presented either in an alarm list or embedded in operator graphics.
and event-triggered reports can be configured to query real-time and historical data. Periodic reports can be set up for hourly, shift, monthly, etc. Event-driven reports can be configured to record start/end time, duration, time-stamped max/min values, etc., and triggered by a digital point. Fault Detection and Diagnostics Fault detection and diagnostics is central to system stability and reliability.
operated in either fixed pressure or variable pressure operation. CCS is an integrated control design that ensures safe and efficient coordinated unit operation. Boiler Control System (BCS) BCS provides automatic combustion control of the combustion process. Based on the steam load demand, BCS controls combustion by coordinating fuel, air, and furnace pressure.
ECS offers the following advantages over the traditional control systems: • Standardized system configuration for convenient logic analysis • User-friendly graphical interface with detailed instructions and help information • Sequential control functions to prevent operator errors • Grounding management interlocks to provide safe maintenance operation • Highly visible and intuitive indicators for alarming Advanced Solutions Real-time Optimization Efficient management of unit operation requires ti
time and historical operation data for all production systems. Data is presented in tabulated or graphical form. Data includes process data, plant-wide equipment conditions, critical operating parameters, and performance conditions. Operation Performance Instructor This is a set of performance analysis and support tools for plant operators: • The operation performance analysis system delivers thermodynamic performance information for component, unit and plant.
The simulator can support a miniature version of the DCS. This configuration can be used for system hardware troubleshooting. The Mini-DCS can be used for testing suspect I/O cards for fault diagnosis and spare parts. The simulation system is portable and can be installed on a laptop. Troubleshooting can be done live at site. Advanced Control and Optimization Knowledge Cubed* (Kn3) Advanced control and optimization solutions are essential tools for today’s competitive market.
conditions. Coalogic can reduce fuel costs, help emissions control, increase fuel flexibility, and it also monitors fuel costs in real-time. Coal Boiler Optimizer* (CBO) CBO is an optimization application for coal-fired boilers. This on-line optimization can be applied either in open or closed loop. It is designed to improve combustion efficiency and reduce emissions.
