An improved system for routine performance testing in fossil plants
- Tennessee Valley Authority, Norris, TN (United States); and others
A data acquisition and analysis system has been developed that reduces the time and labor required to perform routine performance tests on power plant components. The system uses modem data acquisition and computation technologies to integrate the process of data acquisition, data analysis, and reporting of results. During a test run, the data acquisition system reads the data and transfers it to a Microsoft Excel workbook via a dynamic data exchange (DDE) link. In Excel, the system computes and displays real-time trend plots. Real-time plots typically include a display of precision errors, thus providing an immediate indication of the quality of the current test. Upon completion of a run, the system saves results and creates plots in a workbook dedicated to test results. The plots can display computed values such as turbine or boiler feedpump efficiency. Benchmark data can also be included in the plots to provide immediate feedback concerning the change in the performance of a component and the dollar cost due to the performance change. The data tables and plots provide a preliminary report that is available immediately upon completion of the test.
