A case study of transient and dynamic performance of saturated core reactor Static Var Compensator

Abstract

Abstract. This paper presents results related to transient, dynamic and steady state response of a Saturated Core Reactor Static VAr Compensator (SCR-SVC) at regulating a real radial 230 kV transmission line supplying a low density and highly distributed load in a developing area of Brazil. The studies are carried out using a time domain computational simulator in which a comprehensive model for a given twin-triple saturated reactor compensator model was implemented to cope with the receiving end load requirements for voltage regulation. Investigations are then performed to highlight the overall system and reactive compensator behavior at the occurrence of the reactor switch on conditions, final load relief and harmonic distortions.
