Las Vegas is the 2005 location for what its sponsors describe as the world's largest power generation conference. "This is Global" is the theme for this year's Power-Gen International, which runs Dec. 6%%MDASSML%%8 at the Sands Expo & Convention Center. Products featured at the show include a wide range of primary and standby systems. Here, we offer a brief look not only at power generating equipment, but also related products from companies that will be exhibiting at the show.

Diesel gensets comply with new EPA Tier 3 stationary generator requirements that are scheduled to go into effect Jan. 1, 2007. Based on the manufacturer's 9-liter inline 6-cylinder diesel engine, the sets offer low emissions and fast transient response to load changes. NOx emissions are reduced by 40% from Tier 2 levels without the use of complex external hardware or exhaust aftertreatments. (DSHAA generator by Cummins Power Generation) RS#16

Uninterruptible power supply for factory environments provides battery backup for process-critical devices, such as industrial PLCs, data-logging HMIs and control panels, in case of power outage. Units are offered with an optional integrated network management card, giving the user the ability to monitor UPS from a standard web browser. (1609 by Allen Bradley) RS#17

Gen-drives have gross power outputs up to 755 kWm and are suitable for prime and standby power applications. The product comes as a complete engine package that includes a base engine, cooling system and an air filter. An electronic common-rail fuel injection system is claimed to improve performance, lower noise and reduce fuel consumption. (NEF, Cursor and Vector by Iveco) RS#18

Fuel cells are now a standby power generation option for the manufacturer's modular power and cooling packages for data centers. Systems are comprised of an automatic transfer switch coupled with a diesel generator or a fuel cell. With fuel cells, users can realize zero harmful emissions. Unlike standard extended runtime options, one can monitor and manage the system's ability to operate even when the components are turned off. (InfraStruXure by APC) RS#19

Backup power for security systems offers low- and medium-voltage on-site power with single or multiple generators. The systems will automatically pick up critical loads if normal power is lost, to keep security equipment online and help ensure site security. PLC controls automatically start and stop prime movers, annunciate prime-mover status and alarms and control priority loads. (by Russelectric) RS#20

Aeroderivative gas turbine operates in both simple-cycle and combined-cycle, and in its fourth upgrade, will be available in standard and dry low-emission combustion models capable of burning natural gas, fuel oil or both. The combined-cycle mode relative to the precursor model is expected to have an 8.5% power and 0.75% heat rate advantage. (LM2500+G4 by GE Energy) RS#21

Terminal block product line features a soft pivot actuator design that makes it cost-effective and easy to use for wire gauges up to 14 awg. The product family includes twins, hybrids and a new fusing option. Since there is no need to strip the wire, the connection system can save up to 60% of wiring installation time. (QTC terminal blocks by Phoenix Contact) RS#22

Inverter generators are suited for use with sensitive electronics such as computers, printers and electronic test equipment because they produce a clean sine wave of energy that prevents surging. Three new models are offered, rated at 1,650 watts, 3,200 watts and 4,300 watts maximum. Operating noise levels are 58 to 62 dbA. (by Baldor) RS#23

Ultra-quiet generators have a patented soundproof housing, with sound levels from 56 dBA to 63 dBA full load at 23 ft. The series features an upgraded environmental package with an integrated fuel tank and fluid containment system, improved fuel efficiency and voltage regulation. There are six single- and three-phase models, with outputs ranging from 25 kVA to 150 kVA. (Ultra-Silent by MQ Power) RS#24

Double-conversion online UPS is available in 10-kVA and 15-kVA models, both of which are claimed to feature 91% efficiency, extended battery runtimes and cooler operating conditions. A sleek tower design is said to be half the size of comparable three-phase UPS on the market, reducing the demand for space in crowded data centers. (Powerware 9355 by Eaton) RS#25

UPS system is designed to support full loads for a minimum of 30 sec. and partial loads for a maximum of 60 sec. Medium-voltage systems deliver a maximum of 2.5 MVA (per container) and switch critical loads from the utility service to standby battery source in 2 to 4 milliseconds. As many as eight 2.5-MVA containers can be paralleled to protect larger loads up to 20 MVA. Low-voltage systems are modular and scalable from 313 kVA up to 2,500 kVA for 208%%MDASSML%%600 volt applications. (PureWave by S&C Electric) RS#26

CAD catalog provides users with a complete CAD library for low-voltage drive products. The catalog offerings include items for users of 2-D AutoCAD and 3-D drawings. Access to the catalog is via the web. Users need to create an account to use the software. This provides them the ability to select the drawing formats they need and provides the company with information it needs to send them the drawings via e-mail. (Online catalog by ABB) RS#27

Generator control system is a multiple-mode architecture that allows changing of operating modes without significant addition of components. This allows operators of on-site generators to select the most efficient mode based on fuel costs and other considerations. The system can be used on generated voltages from 120/208 volts through 15 kV. (Evolution by Enercon) RS#28

Gas-turbine genset is a cold-end-drive, single-shaft model for cogeneration, combined-cycle and other industrial power generation applications. Rated at 6000 kW for continuous duty at ISO conditions, the unit is said to be especially suited to CHP applications because of its thermal efficiency, coupled with high exhaust temperature and low emissions. (Taurus 65 by Solar Turbines) RS#29

Power supply is a 30-amp three-phase switching model that features "universal auto-ranging input," which means that the same part can be used with 340- to 550-volt AC and provide a 24-volt DC output. A key feature of the unit is the user-selectable output protection. The user can easily select hiccup or constant power protection based on the application. (DIN Rail Power Supply by ASI) RS#30

Regulated DC power supplies are available in seven new models. Solutions include four new single-phase input, 3-, 5-, 10- and 20-amp, 24-volt output power supplies, as well as three new three-phase input, 10-, 20- and 40-amp, 24-volt models. An added power-boost feature enables each power supply to withstand up to 130% of its rated current for up to 5 seconds, making it ideal for applications with inductive loads. (by Weidmuller) RS#31

Switching power supply is available in five new models. At 6.7 watts per cubic in., the units will deliver up to 130 watts of total power with output voltages of 3.3, 12, 15, 24 and 48 volts, and can deliver their full rated output of 130 watts with 30 cfm forced air or 80 watts with convection cooling. The units feature active power factor correction to minimize input harmonic distortion. (by Emerson/Astec Power) RS#32

Unit substation is equipped with an Ethernet interface and provides access to power system information—including transformer coil temperatures—using a standard web browser. It includes a temperature controller that provides remote access to transformer data, in addition to its primary role in controlling cooling fans. The user can monitor transformer coil temperatures per phase and verify cooling fan status, making it possible to correlate circuit loading with transformer temperatures.
