Engine & Turbine Technology
met all their specifications long before a prototype was built. Pervasive parameter management was performed quickly and easily by changing design parameters. Tese parameters were propagated throughout the entire design system, from CAD model through meshing and boundary conditions to generation of updated results.
Te next step was building and testing a real-scale
prototype to verify the simulation results and to ensure the generator’s functionality and life expectancy. Two types of testing were performed at the test bench: generator full- load homologation testing to certify generator performance and durability testing to verify its reliability over time.
Te electrical and thermal measurements of the physical prototype matched up very well with the simulation results. For example, the maximum deviation from the voltage shape prediction to the measured values was 0.1 per cent. Te measured efficiency of the new generator was 97.86 per cent, higher than the design target of 97.7 per cent, and nearly exactly what was predicted by the simulation. Te rating is one of the highest levels of efficiency for
any permanent magnet generator on the market. Simulation made it possible to achieve this challenging performance goal in less than half the time that would have been required using conventional build-and- test methods. Te simulation predictions correlated well with physical testing, providing
confidence that Indar can use simulation to optimise its products to deliver high performance under the most demanding conditions. ●

Fuel delivery system crucial to combustion turbine installation
ne of the most critical components of any combustion turbine installation is the fuel
delivery system. Young & Franklin has assembled a fuel
skid comprised of four YF 3010E500 Series Electromechanically Actuated Gas Control Valve Assemblies (two 2-in and two 1-in line
sizes) and one YF 9200D490 Series Double Block & Bleed Isolation Valve Assembly to maximize efficiency and eliminate varnish issues common in hydraulic controls. The first electromechanically actuated
DLN-2.58+ skid was first commissioned on a GE Oil & Gas Frame 5002E, which is a new 34 MW Turbine used for dual application (pipeline compression or power generation) in October of 2007 for field testing on a European site.
This first installation has
been running for nearly four years (accumulating more than 31 000 firing hours) and has had zero issues. This technology is new to GE Heavy Duty Turbines; to date there are 28 of these systems operating in the field. GE Oil & Gas personnel
have had only praise for the all-electric fuel delivery skid: “It runs flawlessly and

is by far the best control system we have seen and used.” The DLN-2.58+ skid described is running
on choked flow valves; Young & Franklin has since developed an unchoked flow valve that opens up this system for many new applications. Founded in 1918 and headquartered in
Liverpool, New York, USA, Young & Franklin Inc is a design and manufacturing company for industrial combustion turbine fuel control systems. Globally, its products are installed on
more than 23 000 turbines used for land as well as offshore platform based power generation and pipeline compressor drives. Currently in development is the
company’s YF8650 Electric IGV Actuator, due for release in 2012. It is designed to improve air control, responsiveness and overall turbine performance by eliminating the use of oil; zero oil = zero varnish issues. ●
