When you rely upon us to design your test, we will give you advices on the best way to achieve the most accurate result, from instrumentation to test execution.
As a centre for metrology, SINT owns a wide range of instrumentation for turbine performance testing. Our pressure transmitters, thermocouples, thermoresitances and wattmeters will come to your site provided with updated calibration certificates traceable to EA-ILAC organizations fulfilling the accuracy requirements of the major international codes.
Our test engineers will cooperate with plant personnel for the achievement of the smoothest test schedule possible, in order to minimize the impact of test execution on plant production.
Temporary additional instrumentation, to be used for the test, will be installed by SINT personnel in parallel to plant permanent one. This will allow to maintain all field measurements relevant to the plant control system active and also to double-check the proper functioning of plant instrumentation.
It is our common practice to check all flow measurement devices against relevant codes (or manufacturer’s datasheets) to confirm their proper calculation. Process gas thermodynamic properties are computed using a library of real gas Equations Of State and choosing the most suitable one.
In steam power plants and combined cycles, the test of the steam turbine performance is tightly bonded to the proper operation of the boiler. Feed water mass flow measurement, using suitable flowmeters as prescribed by ASME PTC 6 Code, is recommended for an accurate evaluation of the steam turbine efficiency.
SINT engineers will set up the Data Acquisition System, recording data from additional instruments and implementing real-time performance calculations. We will take care of checking the thermodynamic stability of your turbine and will choose the best test time interval for performance evaluation.
Gas and steam turbine performance curves, supplied by the manufacturer, are uploaded to the Data Acquisition System in order to provide our Customer with the test results at contractual reference conditions. After the test is completed, a detailed technical report will be issued.
