Turbine systems are supported by hydraulic pumping and cooling systems that are used to transfer heat losses from equipment, such as converters and generators, outside of the turbine. ABB products such as motors and drives are used in these systems.
Motor control and protection
ABB produces safe and reliable products and solutions for all motor applications. These solutions are available for different motor types, and enable different starting methods as well as coordinated solutions for protection and control of motors. Products include AC and DC drives, softstarters, contactors, manual motor starters, back-up breakers/short-circuit limiters, temperature monitoring relays, and overload relays. In addition, motor starters can be integrated on the SMISSLINE plug-in system to reduce space, wiring complexity and installation time.
Motor for pumping
ABB AC motors are used in hydraulic pump applications in the turbine. They are available from 2 to 8 poles, 0.06 to 55 kW, for all common voltages, and are available with IE3 premium efficiency requirements.
Motor for generator cooling
ABB’s motors are used to power the generator’s heat exchange and ventilation systems. They are tailored for the operating requirements unique to the installation in the turbine’s nacelle.
− Typically 0.75 to 7.5 kW
− 2, 4, or 6 pole motors
− Two speed 2/4, 4/8, or 4/6 pole motors available
Low voltage AC drives for pumps and fans
ABB has developed drives with built-in pump and fan applications that are designed to improve pump and fan performance and efficiency. The drives also reduce mechanical wear on systems by providing pump and fan protection functions such as soft pipe filling, multi-pump control, preventing pump dry-run, and configurable fan application settings.
ABB softstarters are used for reducing mechanical stress from motor startup. They are used with motors for hydraulic systems. They reduce initial motor starting current draw and enable smooth motor acceleration and deceleration.
Back-up breaker/Short-circuit limiter
ABB’s short-circuit limiter breakers, WT63 and S800S-SCL-SR, are used for coordinated protection in motor applications up to 690 V, enabling selectivity and minimized installation space when used as back-up for several motor starters.
