Turbomachinery Package Specification

Titan 250 Generator Set

 

 

a post-lube cycle to protect the gas turbine and driven equipment bearings from thermal damage.

If the shutdown is the result of fire being detected, the turbine is brought to a complete stop and the start of the post lube cycle is delayed for 10 minutes, unless an operator intervenes.

9.4.4Vibration and Temperature Monitoring

In addition to the T5 thermocouples, the system provides continuous monitoring of temperature and vibration levels at key package locations. Refer to the Specification Table for details.

9.5TT4000 Display and Monitoring System

The TT4000 display and monitoring system provides extensive data collection and display capabilities. On a typical project, two standard versions of the product are used.

TT4000 is the fully featured version with extensive data collection and display capability. It is installed in a high performance industrial grade personal computer (PC), in either a desktop or a console panel mounted version. It runs on the Windows 2000 operating system. The hardware is not rated for hazardous areas and must be installed in a non- hazardous area, typically a control room. Note: this full TT4000 version is required for the engine performance map option.

TT4000S is a reduced version of the product specifically designed for the onskid interface. It is installed in a special industrial grade PC that is approved for use in both NEC Division 2 and CENELEC/ATEX Zone 2 areas. It runs on the embedded Windows XP operating system. Due to the environment, it uses no moving media such as disk drives, so data storage is limited. It displays data but without the graphics features of the full TT4000 version.

9.5.1TT4000 Display Screens

A menu bar at the left of each screen allows navigation to any other screen. A status bar at the top of every screen displays up to four alarm conditions. Standard display screens include:

•Operation Summary (complete package data, Figure 15)

•Generator Summary (generator operating data)

•Temperature Summary (all monitored temperature values)

•Vibration Summary (all monitored vibration values)

•Alarm Summary

•Discrete Event Log

•Strip Chart Display (real time data, Figure 16)

•Historical Data Display (strip chart format)

•Program Constants

Optional Display Screens:

•Gas Turbine Performance

Customized screens can be provided to display other product specific information.
