This paper presents a new general‐purpose state‐space synchronous machine model based on the voltage‐behind‐reactance (VBR) formulation which accounts for main flux saturation. The proposed model has a numerically efficient constant‐parameter decoupled RL branch interfacing circuit comprised of the stator and field windings. Consequently, the new model can be interfaced directly with arbitrary power networks and exciter circuits. The presented studies, executed using the Simulink toolbox PLECS, demonstrate the superior combination of numerical accuracy and efficiency of the new VBR model compared with existing state‐of‐the‐art models. As a result, the proposed model would be a desirable addition to the built‐in component libraries of many industry‐grade state‐variable‐based transient simulators.
