Abstract

A unified data acquisition system (UDAS) includes a portable computer configured to monitor data from a system installation. The system installation may be a gas turbine, steam turbine, combined cycle, or power generation system installation. The UDAS is also configured to log both raw and processed data from a plurality of data sources at the system installation, and to permit relocation and reconfiguration of the UDAS at a different system installation for monitoring and logging of data at the different system installation.

Claims

1. A unified data acquisition system (UDAS) comprising a portable computer configured to:

monitor data from a system installation selected from the group consisting of gas turbine, steam turbine, combined cycle, and power generation system installations;

log both raw and processed data from a plurality of data sources at said system installation; and

permit relocation and reconfiguration of said UDAS at a different system installation for monitoring and logging of data at said different system installation, said UDAS is reconfigurable utilizing a graphical user interface to utilize a plurality of data acquisition instrumentation from a predefined list of said data acquisition instrumentation.

2. A UDAS in accordance with claim 1 wherein to log both raw and processed data from each said monitored installation, said UDAS is configured to log raw data in a comma separated value formatted file and said processed data in a relational database.

3. A UDAS in accordance with claim 2 configured to time-synchronize the logging of raw data from a plurality of sources in said comma separated value formatted file, and to time-synchronize the logging of processed data from a plurality of sources in said relational database.

4. A UDAS in accordance with claim 1 further configured to transmit test status and current data to a remote location.

5. A UDAS in accordance with claim 4 configured deployed as a performance monitor at a monitored system installation to process data from the monitored system installation essentially concurrently as it is received.

6. A UDAS in accordance with claim 4 wherein said UDAS is configurable to perform custom calculations with said data from the monitored installation utilizing instructions specified by a user of said UDAS.

7. A UDAS in accordance with claim 6 wherein said UDAS is further configured to offer a selection of preprogrammed performance testing functions to the user.

8. A method for acquiring data for thermal performance testing, said method comprising:

utilizing a portable data acquisition system to monitor data from plurality of data sources at a system installation selected from the group consisting of gas turbine, steam turbine, combined cycle, and power generation system installations, wherein said portable data acquisition system comprises a personal computer relocatable and reconfigurable for monitoring and logging of data from different system installations;

logging both raw and processed data from the monitored system installation; and

reconfiguring said personal computer via a graphical user interface to utilize a plurality of data acquisition instrumentation from a prefined list of said data acquisition instrumentation.

9. A method in accordance with claim 8 wherein logging both raw and processed data further comprises logging raw data in a comma separated value formatted file and logging said processed data in a relational database.

10. A method in accordance with claim 9 wherein raw data is logged from a plurality of sources and processed data is logged from a plurality of sources, and further comprising time-synchronizing the logging of raw data from a plurality of sources in said comma separated value formatted file and time-synchronizing the logging of processed data from a plurality of sources in said relational database.

11. A method in accordance with claim 8 further comprising transmitting test status and current data to a remote location and processing data from the monitored installation essentially as it is received.

12. A method in accordance with claim 11 further comprising at least one of configuring the personal computer via a graphical user interface to perform custom calculations with said data from the monitored installation or selecting preprogrammed performance testing functions.

13. A machine readable medium having recorded thereon instructions executed by a processor for executed by a processor acquiring data for thermal performance testing, said instructions configured to:

instruct a portable data acquisition system to monitor data from plurality of data sources at a system installation selected from the group consisting of gas turbine, steam turbine, combined cycle, and power generation system installations, wherein said portable data acquisition system comprises a personal computer, and said instructions include instructions for monitoring and logging of data from different system installations;

log both raw and processed data from the monitored system installation;

reconfigure the personal computer via a graphical user interface to utilize a plurality of data acquisition instrumentation from a predefined list of said data acquisition instrumentation.

14. A machine readable medium in accordance with claim 13 wherein to log both raw and processed data, said instructions are further configured to log raw data in a comma separated value formatted file and to log said processed data in a relational database.

15. A machine readable medium in accordance with claim 14 wherein said instructions include instructions to log raw data from a plurality of sources and to log processed data from a plurality of sources, and said instructions further include instructions configured to time-synchronize the logging of raw data from a plurality of sources in the comma separated value formatted file and to time-synchronize the logging of processed data from a plurality of sources in said relational database.

16. A machine readable medium in accordance with claim 13 wherein said instructions further comprise instructions configured to transmit test data and current data to a remote location and to process data from the monitored installation essentially as it is received.

17. A machine readable medium in accordance with claim 16 further having instructions recorded thereon to at least one of configure the personal computer via a graphical user interface to perform custom calculations with said data from the monitored installation and provide preprogrammed performance testing functions selectable via said graphical user interface.
