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.

16.2.3Generator 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.

16.2.4Acceptance 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

16.2.5Additional 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.
