A full-order, voltage-behind-reactance synchronous machine model has recently been proposed in the literature. This paper extends the voltage-behind-reactance formulation for the electromagnetic transient program (EMTP)-type solution, in which the rotor subsystem is expressed in qd coordinates and the stator subsystem is expressed in abc phase coordinates. The model interface with the nodal-analysis network solution is non-iterative and simultaneous. An example of a single-machine, infinite-bus system shows that the proposed model is more accurate and efficient than several existing EMTP machine models
