T6200 Compressor and Turbine Unit Controller Features |
A single T6200 can handle centrifugal/axial compressor control applications ranging from a single-stage compressor up to three independent stages, making it a completely integrated compressor control system. This scalable adaptability reduces overall system complexity and cost. The Controller's universal hardware architecture and control flexibility permit configurations from anti-surge to complete performance control (capacity, load-sharing, decoupling, startup/shutdown) as required by each application. This control optimization results in energy savings, operation simplicity and high reliability. The advantages of using the T6200 controllers: • Advanced Surge Control: Operating point tracking, look-up table curve fit and adaptive gain all contribute to the ability to safely operate the compressor close to the surge limit line. • Incipient Surge Detection/Control (T6050 SurgeGard): Detects oscillations that occur as a precursor to surge. The incipient surge detection is independent of the compressor performance map. SurgeGard provides for a wider compressor operating window. • Integrated Performance Control: Includes capacity control, suction and discharge pressure control and motor horsepower override. • Load Sharing: Ensures that load is equally balanced among machines. Results in high load efficiency. • Automated Start-up, Sequencing and Shutdown: Runup, rundown, purge, loading and decoupling control are coordinated between stages, the compressors and the process/pipeline. The process can be put on-line quickly and consistently. • Sequence of Event (SOE): Build-in 1msec SOE resolution enables first-out detection and assists in machine trouble shooting. • Control Strategy Flexibility: Extensive library of control functions allows the addition of custom-defined strategy and the adaption to any field condition. • Redundancy: 100% (1:1) redundancy (including I/O circuits) ensures uninterrupted control. • Fallback Algorithms: Allows for continued, safe operation in the event of a transmitter failure. • Universal Control Board: Integrates intelligence, I/O and communication on one board. Minimizes spares and space. • Open Communication: Supports OPC (over redundant Ethernet) and Modbus communications. The T6200 also features the following HMI qualities: • Advanced Graphics: CE Windows based full dynamic HMI graphics. • Trend and Historian: Allowing machinery and process performance trending. • Alarm and Alarm History: Comprehensive alarm indication and summary. • Communication Services: Publishing real-time dynamic graphic screens, trends, alarms and reports to standard internet browsers. Imports and exports real-time data to XML format. • Unit Asset Management (UAM): Incorporating real-time asset management features for Plant Asset Management (UAM with OPC connectivity). Each T6200 Controller is individually factory pre-configured with the control functions appropriate for the particular compressor application and requires only minor tuning to be placed in service. The T6200 provides better operational efficiency and increased safety through advanced Turbomachinery Control.
