CAT Titan 250 - Manual (Page 65)

Turbomachinery Package Specification Titan 250 Generator Set
• Vibration measurements
• Power and heat rate measurements at partial and full load under ambient
conditions with a unity power factor of 1.0
• Turbine and generator temperature measurement
• Variable guide vane adjustment
• Generator and engine tuning
• Fuel transfers (for dual fuel units)
• Load/speed transient testing
• Malfunction and safety devices testing
• AC metering and control circuitry testing (if AC metering is supplied), calibration
of AC metering circuits is performed by bench testing
The package is usually tested with the generator. When this is not practical due to
schedule availability or test cell limitations, the package may be tested with a slave
generator. Prior to shipment, the contract generator will be mounted and aligned on the
package. Items excluded from standard package testing are inlet and exhaust systems,
ancillary equipment such as filters, silencers, ducting, battery systems, oil coolers,
ancillary skid, switchgear, and any customer-furnished hardware.
16.2.3 Generator Testing
The generator is tested in accordance with the Institute of Electrical and Electronic
Engineers (IEEE) standard specifications and Solar's specifications at the manufacturer's
plant. These tests satisfy both Solar and National Electrical Manufacturers Association
(NEMA) requirements. Supplier testing is performed under periodic quality control review
by Solar to ensure conformity.
16.2.4 Acceptance Test Data
Acceptance test data are reviewed and approved by Test Engineering, Quality
Engineering, and the project manager prior to submittal to the customer. With this review
and approval cycle, the test data are furnished approximately four weeks after completion
of acceptance testing. The test data includes test result comparisons to Solar's
acceptance test specifications using calculations, graphs, strip charts, and descriptions.
Data are provided for each turbine generator set. The acceptance test data generally
includes the following:
• Turbine fuel consumption rates – a comparison of measured fuel consumption
versus specified fuel consumption that shows a correlation between fuel
consumption, power output, and turbine gas temperature at full load.
• Voltage and frequency transients – strip chart traces are provided that show
voltage and frequency deviations during load transitions.
• Operating values – a chart that includes the following operating parameters at
each step load from no load to full load:
− Lubricating oil pressure, temperature, and flow
− Package temperatures
− Generator power
− Generator voltage, amperage, and frequency
− Engine compressor discharge pressure
− Package vibration levels
16.2.5 Additional Testing
As an option, additional testing can include a four hour full-load test using gas and/or
liquid fuel, factory emissions testing, and field performance testing.
