Hydroelectric generators have up to 70% more power

Two series of efficient, high quality and compact hydroelectric generators – GH11 and SH11 – with up to 70% more power density than previous models have been announced by WEG.

Engineers can benefit from a low weight and space-saving solution for easier installation, says the company. The generators are  available with short lead times, helping hydroelectric power stations to reduce downtimes and increase productivity. With rated capacity from 500 to 18,000 kVA., the GH11 and SH11 8-pole to 36-pole hydroelectric generators are available with frame sizes from IEC 630 to IEC 1800 and output voltages from 400 V to 13.8 kV at 50 or 60 Hz.

The hydroelectric generators provide reliable performance, says WEG. The GH11 series is designed for standard applications with relatively small and simple turbines, while the robust SH11 series is designed to meet more demanding specifications for turbines and complex hydroelectric power stations. The SH11 generators have a modified mechanical and electrical design that allows them to be operated with higher inertial forces and relatively large axial and radial loads despite their compact construction. They can also withstand adverse conditions such as high continuous speeds or load shedding.

WEG’s generators are easy to install and commission in existing plants because the design is based on a standard technology platform.  WEG has standardised the production of the new generators and key components are provided in the preliminary design stage.  As a result, the manufacturing process is therefore similar to series production and end users can benefit from shorter delivery times. The generators are highly versatile and can be easily adapted to individual application specifications.

“WEG is committed to helping its customers increase efficiencies throughout its process, and this includes reducing downtime. By delivering products to customers as fast as possible means they can get their process up and running quickly, therefore maximising productivity and profitability,” says Marek Lukaszczyk, European & Middle East Marketing Manager at WEG.

Both the GH11 and SH11 can be installed either horizontally or vertically and are available in versions for brushless excitation (with or without an auxiliary exciter) or static excitation with brushes.
