In this paper the static var compensator (SVC) has been accurately incorporated into the structure preserving energy function (SPEF) with a detailed generator model including flux decay and transient saliency, automatic voltage regulator (A VR) and damper winding. The SVC can be modelled for transient stability studies using the steady-state control characteristic and is treated as a voltage-dependent reactive power load. This simplifies simulation and results in the derivation of an exact path-independent energy function to account for the effect of the SVC inclusive of its limits. Application of this SPEF to transient stability evaluation is illustrated with a numerical example including the critical case of a three-phase fault with line outage.
