Synchronous generator system is a complicated dynamical system for energytransmission, which plays an important role in modern industrial production. Inthis article, we propose some predictor-corrector methods andstructure-preserving methods for a generator system based on the firstbenchmark model of subsynchronous resonance, among which thestructure-preserving methods preserve a Dirac structure associated with theso-called port-Hamiltonian descriptor systems. To illustrate this, thesimplified generator system in the form of index-1 differential-algebraicequations has been derived. Our analyses provide the global error estimates fora special class of structure-preserving methods called Gauss methods, whichguarantee their superior performance over the PSCAD/EMTDC and thepredictor-corrector methods in terms of computational stability. Numericalsimulations are implemented to verify the effectiveness and advantages of ourmethods.
