A Voltage-Behind-Reactance Synchronous Machine Model for the EMTP-Type Solution

Summary form only given. 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 EMTP-type solution, in which the rotor subsystem is expressed in q-d 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.
