要約(英語): One of the models for rotating machines such as synchronous machines and induction machines is the phase-domain model, which is characterized by formulating the circuit equations of the rotating machine in the phase domain and solving them simultaneously with the external system to which the rotating machine is connected. Although this model has excellent numerical stability and calculation accuracy, it requires refactorization of the subcircuit including the rotating machine at each calculation time step, which degrades the calculation speed. This paper describes the results of an attempt to improve the calculation speed when using the phase-domain model by using partial refactorization, which makes the refactorization process more efficient.
