Development of a Numerical Model of a Turbogenerator to Create a Database for Monitoring

The paper discusses the results of scientific work on the creation of a digital model of the turbogenerator for online monitoring. The feature of the developed model is the use of numerical modeling of electromagnetic fields to obtain a database of parameters in various operating modes. The numerical model of a turbogenerator in a two-dimensional formulation is presented, intended to determine parameters in steady-state operating conditions. Method for determining model parameters for given operating modes is described. The developed model was verified based on comparison with data from the automatic process control system (APCS) of a real turbogenerator.
