Alternator for cogeneration applications

- Advertisment -

Nidec Leroy-Somer announces the launch of the LSAH 44.3, an alternator designed for cogeneration applications in district heating. This new alternator incorporates an optimised heat recovery system directly connected to the heating circuit, enabling it to reach leading electrical and thermal efficiency values.

The unit was designed to be built into small natural gas generator sets for applications which require both heat and electricity. The main application of these gensets is central heating in residential and public buildings.

To maximise the heat recovery process, this alternator was designed with a high-performance liquid cooling circuit which connects directly to the heating system’s piping network. It has been optimised and qualified to operate at high temperature, with a maximum operating temperature set at 80°C.

The unit delivers a rated power of between 50 and 94 kVA at 50 Hz in continuous service. The alternator is fitted as standard with an AREP excitation system and a D350 regulator. Paralleling with the public network for the resale of surplus electricity generation is also possible. Thanks to its cooling and heat recovery system, the unit offers a range of high-performance features:

  • Electrical efficiency reaches 97% and generally remains above 95%, allowing optimised operation and quicker profitability
  • The optimised cooling system extends the machine’s lifespan even in continuous operation without risk of failure due to hotspots.
  • Water cooling allows the unit to be used in non-ventilated – and silent – generator sets, making their integration in buildings much easier.
  • Mechanically, the unit offers two-bearing or single-bearing couplings and regreasable bearings.
  • The structure has also been strengthened and stiffened for better resistance to vibrations.caused by gas engines, and the machine itself has been optimised to limit generated vibrations.
  • The unit is compatible with the most demanding grid codes or network requirements.
