Hydrogen Cooled Generators and Water/Hydrogen Cooled Generators
Hydrogen cooled generators are lower maintenance than water/hydrogen cooled generators and can produce higher efficiency at the same capacity. Moreover, through the latest technologies such as the application of the High Heat Transmission (HHT) insulation system developed in-house by Mitsubishi Power on the stator winding, 900 MVA class capacities previously only supported in water/hydrogen cooled generators can now be achieved with hydrogen cooling. On the other hand, water/hydrogen cooling can support capacities exceeding 1,000 MVA, and a more compact generators can be set up for a given capacity compared to a hydrogen cooled generator.
Hydrogen Cooled Turbine Generator
- A generator that uses hydrogen gas as its coolant to indirectly cool the stator winding and directly cool the rotor winding.
- As no stator cooling water equipment is required, this type offers superior performance in terms of operation and maintenance.
- Higher efficiency compared with a water/hydrogen generator of the same capacity.
Water/Hydrogen Cooled Turbine Generator
- A generator that uses water as the coolant for the stator winding.
- Achieves high capacity in a compact footprint through high cooling performance.
- Single generator capacity of greater than 1,000 MVA can be achieved.
