FIELD PERFORMANCE VERIFICATION TESTING
The objective of site testing is typically to determine that the equipment furnished meets, at a minimum,
the guaranteed performance claimed by the manufacturer. At Solar Turbines, we take this very seriously.
In Section 1.0: Factory Testing of this proposal document, our comprehensive test procedures were
described, including:
Test Facilties
Gas Turbine Acceptance Test
Generator Testing
Generator Set Acceptance Testing
With the availablility of dynamic Generator Set Acceptance Testing of the generator set package, in an
instrumented and calibrated test cell, and a corresponding test report; this might well be considered an
alternative to site testing.
However, where endurance testing of the installed equipment is desired, or site performance verification
testing is otherwise required, Solar offers a service product to meet your specific needs.
Field Performance Verification Test Procedure
The declared Solar gas turbine generator set performance, and reference conditions associated with such
performance are specified in Section 3.0: Performance and Emissions, of this proposal. These
performance values are demonstrated during factory testing, and in instances where Solar has
guaranteed performance, compliance with such guaranteed performance is evaluated based on the
factory test results.
Customers frequently request that performance values demonstrated during the factory tests be verified
through field testing at site, and this document defines the test objectives and procedures for such field
testing, to verify the Output Power and Heat Rate performance of the Solar gas turbine generator set(s).
Solar Turbines has participated in the start up and site performance verification on thousands of gas
turbine generator sets. This procedure has proven to be an effective way to verify proper package
performance (Output Power and Heat Rate) for both the customer and Solar.
Test Description
Test Conditions. Engine performance testing at Solar’s factory allows the engine to be operated in
steady, closely controlled conditions with redundant, calibrated instrumentation. Factory testing
performed by Solar typically allows the most accurate evaluation of engine performance. The field tests
described herein are intended to provide a site verification of the declared performance values for Output
Power and Heat Rate, based on data obtained from the permanently installed package instrumentation,
and other sources, such as Customer instrumentation. Other factors affect the field verification test
results, such as power transformer (PT) and control transformer (CT) accuracy, the accuracy of the fuel
analysis, etc.; many of which are beyond Solar’s scope of control. This results in a field test with an
inherently lower accuracy than the factory test, and an allowance for this uncertainty must therefore be
considered when evaluating the field test results as further explained herein.
