The steady-state initialization of large object-oriented thermo-hydraulic networks is a difficult problem; because of the sensitivity of the convergence to the initial guesses of the iteration variables. This paper proposes an approach to this problem based on homotopy transformation; detailing specific criteria for model simplifications in this physical domain. The approach is successfully demonstrated on large power plant test cases; having several hundreds of iteration variables.
