6 FAQs about [Water-cooled generators in power plants]

How does a water cooling generator work?

Water Cooling Generator: Generators with more than 400 MVA ratings require a more efficient cooling method. For this Hydrogen-Water Cooling System is used. The Stator windings are directly cooled by deionized water, supplied by a closed-loop auxiliary system, which flows through hallow copper strands located in the stator windings.

Can a generator be air cooled or water cooled?

The generators can be air-cooled or water- cooled. The cooling is realized by a closed system that circulates the cooling medium (water or oil) over the components and a heat exchanger where it releases the heat to secondary cooling water.

Which components in hydro power generation require cooling?

The following components in Hydro power generation require cooling: Electricity generation in the hydro-generator that is powered by the turbine releases heat that needs to be removed to be able to keep running at optimum capacity. The generators can be air-cooled or water- cooled.

What are the advantages of water cooled generators?

One of the advantages of water-cooled generators is the direct water-cooling of the rotor winding. This cooling method was de-veloped by ABB more than 25 years ago. Technical advances since then have per-fected the method and enhances its effi-ciency. Numerous generators with water- Two-pole, water-cooled ABB generator of advanced design.

Can direct water cooled generators increase equipment capacity?
