A Show of Power
With enactment of the Energy Policy Act of 2005 last year, the power industry was dealt a new hand in the power generation game in coming years. This year's PowerGen International, which convenes Nov. 28 through 30 at Orlando's Orange County Convention Center, will provide some answers to attendees' questions about the new power picture.
With enactment of the Energy Policy Act of 2005 last year, the power industry was dealt a new hand in the power generation game in coming years. This year's PowerGen International, which convenes Nov. 28 through 30 at Orlando's Orange County Convention Center, will provide some answers to attendees' questions about the new power picture. Here's a brief look at what the show will offer.
LP vapor-fueled gensets with ratings of 20, 25 and 30 kW are suitable for a wide variety of standby or prime power applications. Powered by a three-liter industrial engine, models are also available to run on natural gas or LP liquid fuel. The series is said to be especially suited to use with remote cell phone towers, telecommunications switching facilities or small commercial buildings. The units feature electronic control systems and an electronic governor that provides fast response to load changes. Several sizes of alternators are for selectable motor starting capability, low wave-form distortion with non-linear loads and fault-clearing capability.

Automatic transfer switch for 600-volt class emergency/standby applications is single- or dual-operator and available in 2-, 3- or 4-pole configurations. The manufacturer claims its ATS models have the industry's highest 3-cycle closing and withstand ratings and are labeled for use with any circuit breaker with instantaneous trip. UL-listed through 4,000 amps and SCADA capable, they offer front-accessible wiring and rapid arc quenching. IEC-certified models are also available. The dual-operator model is suitable for applications that require the switching of large inductive loads such as three-phase motors or transformers used in pumping stations, sewage treatment facilities, elevator systems, or hospital X-ray equipment.

Gas and diesel gensets are delivered as components of a complete integrated prime standby or emergency power system. Engineered to meet or exceed stringent emissions standards, gas generators range from 9 kW to 5.9 MW, diesel sets from 13kW to 16.2 MW. Gensets feature proprietary technology for Advanced Combustions Emissions Reduction to meet EPA standards. A new line is the first to offer 2- to 4-MW of power in a single high-speed package.

Gas engines tap into an available energy sources, such as industrial waste gases, to achieve CO2 emission savings. Steel production processes typically create large volumes of specialty waste gases. Coke oven gas, generated during the processing of bituminous coal into coke in coke oven batteries, mainly consists of hydrogen and methane. Also, LD-converter gas is created during the steel manufacturing process that converts pig iron to steel. In the past, operators used these steel waste gases to only produce steam in gas-fired boilers. This new technology allows steel factories to also generate electricity while avoiding the need to vent these gases into the atmosphere. (Jenbacher by GE Energy) www.gepower.com #18
Thermocouple assembly provides a reliable temperature monitoring sensor for high-purity fluid systems that traditionally use fluoropolymer components. The sensor assembly overcomes perceived weaknesses with current thermocouple sensors that potentially reduce long-term stability, and is expected to deliver considerable cost savings to users over its lifetime. The assembly has been designed as an alternative to sensors for high-purity flow systems that are fabricated by bonding the thermocouple wires between fluoropolymer tubing elements, a form of installation often carried out by end users.

Tagging relays are designed with serial communications capability and can be used to optimize automated breaker control schemes in new or existing power distribution systems. They can also be used to control remote reclosure cutoff and facilitate the expansion of a SCADA system beyond a substation to distribution feeders. A remote operator automatically places and removes eye-catching orange warning tags, ensuring personnel safety are in compliance with worker-safety tag-out rules. The relays offer two positions and up to 10 decks. Their contact ratings (interrupt) are 20 amps at 120 volts AC and 3 amps at 125 volts DC. Coil burdens range from 9.9 amps at 48 volts DC to 6.6 amps at 125 volts AC. (Series 24 by Electroswitch) www.electroswitch.com #20

Other combinations of power and runtime are available. Other benefits claimed by the manufacturer include low operating and maintenance cost, no bearings maintenance or replacement, no vacuum pump maintenance or replacement, an efficiency greater than 99.8%, low power consumption, quiet operation and easy installation. Multiple units can be run in parallel. (VSSdc+ by Pentadyne) www.pentadyne.com #22
Medium-voltage switchgear represents a paradigm shift in communications technology for power distribution systems, with “waveguide” concept that enables switchgear to communicate data via electromagnetic waves without the use of electrical or optical links. Data is transmitted at almost the speed of light and without interference and transmission loss. Modules equipped with waveguide are able to communicate with their entire environment in accordance with the IEC 61850 standard. (E-panel ZX by ABB) www.abb.com #23
Modular UPS is claimed by its manufacturer to be the world's largest in the 400- to 1,600-kW range. Suited to applications such as large data centers, complete buildings, health-care and other critical facilities, the system can be scaled for increased availability through internal N+1 configurability, predictive failure notification and multi-module paralleling features. With low cost of ownership, best-in-class efficiency and a reduction in rating of electrical infrastructure wires, transformers and generators, the system offers slide-in/out power modules, manageable external batteries and self-diagnosing features that reduce mean time to repair.

Engine genset is pre-configured and pre-engineered for quick delivery. With extended size ranges up to 400 kW for diesel and up to 130 kW for natural gas/LP, the units are said to be easy to install, with silencer mounted plumbed, and insulated water jacket heater mounted plumbed and pre-wired to a terminal strip. They also boast a battery charger mounted and pre-wired to a terminal strip, and on gaseous units, fuel inlet, along with the flow control valve (regulator) and solenoid valve, are plumbed to the outside of the base. Available with UL 2200 and CSA labels, the gensets meet NFPA 110. Low profile and reduced size is aesthetically pleasing, and upsized alternators are standard on most models. (SP Series by Katolight) www.katolight.com #28
Transfer switch controller is an upgraded model that is said by the manufacturer to be designed for flexibility and convenience, and provides a platform to accommodate future power system adaptations. Communication to critical power systems provides essential monitoring through Ethernet or RS-485 LAN line, and both are standard. This allows the user to interface to their own management systems or the manufacturer's propriety software program to see critical information. Whether the power system is local, remote or connected directly to the customer's management system, the controller allows for an integrated interface with the power system.

Gas turbine is driven by a type of internal combustion engine that can be viewed as an energy conversion device that converts energy stored in the fuel to useful mechanical energy in the form of rotational power. The term “gas” refers to the ambient air that is taken into the engine and used as the working medium in the energy conversion process. This air is first drawn into the engine where it is compressed, mixed with fuel and ignited. The resulting hot gas expands at high velocity through a series of airfoil-shaped blades transferring energy created from combustion to turn an output shaft. The residual thermal energy in the hot exhaust gas can be harnessed for a variety of industrial processes. (by Solar Turbines) www.mysolar.cat.com #33
