INDuSTRY PRODuCTS grates directly into the pipeline and completely eliminates the need to change filter bags or clean filtration baskets. The filter element is kept continuously clean, ensuring optimum filtration efficiency. Because of its self-cleaning design, cleaning the filter between batch runs is quick and easy with minimal disruption during production changeovers. The Eco Filter fits neatly into existing production lines, in many instances adding significant capacity without requiring excessive space. Because it’s totally enclosed, it also prevents outside pollutants from contaminating product and protects operators from any fumes or spillage. Russell Finex, Inc. 704.588.9808 Pineville, NC www.russellfinexusa.com generator through to the utility or transmission switchgear, also can be configured in various ways to optimize the number of power modules needed, as a function of the wind power or turbine speed/velocity to the generator,” notes Ari Hedemaki, product line manager for the product line, ABB Low Voltage Drives, North America. “This modular, parallel converter/inverter module configuration also enables wind turbine owners to optimize efficiency – and the system is completely redundant, in that the converters will continue to operate at partial load, even if one of the inverter modules in the system goes offline for some reason.” From 1.5 MW upwards, a full converter system can be configured from two or three individual subsystems, which can be operated together, or one at a time. This approach not only provides redundancy, but also the freedom to choose the optimum location of the frequency converter within a turbine system. The liquid-cooled converter is available for full converter systems with permanent magnet or asynchronous generators, and for doubly-fed asynchronous generators covering powers up to 5 MW as standard. Higher ratings are engineered according to customer demand. The liquid-cooled converter is equipped with the latest software and hardware developments to support the grid compliance of an individual turbine in any given locale. Compliance with local grid codes is essential and highly dependant on the functionality of the frequency converter. ABB has extensive experience in providing converters that support compliance of wind turbine with grid codes such as E.ON, R.E.E and FERC Order 661. The new products are available with output ratings in the 1 to 5 MW range. As a result, the drive can be factory-installed by the turbine manufacturer or OEM, avoiding costly and time-consuming work on site. Scalability means that the same modules can be used for different turbine designs, allowing easier maintenance and servicing, and reduced training needs. Direct Torque Control (DTC) is used to provide fast and accurate speed and torque control, without the need for pulse encoder feedback from the shaft. DTC offers a number of benefits, including robust operating characteristics, high availability and reliability, and high-quality output with low harmonics. Thanks to DTC, the drives maintain good output quality in different wind conditions that vary from light to gusting, and they also tolerate fluctuations in the power network. The use of DTC also helps to decrease audible noise from the generator, which reduces the overall environmental impact. Electrical and reactive power can be controlled independently. PC-based tools make commissioning and service operations straightforward. In addition to the normal fieldbus communications options, a built-in intelligent Ethernet module permits remote maintenance, monitoring and even control. Diagnostic routines can be performed via the Internet or a telecoms line, and the module can trigger alarms in the event of a malfunction. Remote access helps to reduce maintenance costs and minimize downtime. ABB 262.785.3400 New Berlin, WI www.abb.com ABB New Enclosed Liquid-Cooled Frequency Converter BB’s new drive for wind turbines combines advanced technology with totally enclosed cabinet construction. The active and passive power-converting components and controlling electronics are liquid-cooled and enclosed by the cabinet construction with no air inlet or outlet openings. This ensures that harsh ambient conditions do not infiltrate the cabinet – and the electronics are stabilized; the environment inside the cabinet is protected against dust, salt and extreme temperatures. The new converters are offered as part of ABB’s wind turbine drive family, and the model number is ACS800-77LC. “This converter, which transfers AC power from the turbine A Be sure to mention, “I read about it in Food Protection Trends”! 678 FOOD PROTECTION TRENDS | SEPTEMBER 2008 http://www.russellfinexusa.com http://www.abb.com
