Coupled Electromagnetic-Fluid- Thermal Analysis in Large Scale Water-Hydrogen-Hydrogen Cooled Generator-Condenser Under Different Operations

In this article, the electromagnetic performance and stator thermal field of the 350MW/300Mvar water-hydrogen-hydrogen-cooled generator-condenser under different operating conditions are compared and analyzed by electromagnetic-fluid-thermal coupling model. The calculation results from the two-dimensional field-circuit model and the global ventilation network serve as coupling boundary conditions for the solid-fluid solution domain. The conclusions drawn provide useful references for the design and renovation of this type of generator-condenser.
