Analysis of Leakage Inductances in Shunt Reactors: Application to High Voltage Transmission Lines

Abstract

Inductance is one of the main parameters directly related to the reactive powers of Shunt Reactors (SRs) in electrical systems. Thus, the definition and computation of leakage inductances and the ratio of leakage to total inductances play an extremely important role in the design and manufacturing of SRs. In this study, a finite element approach was developed to compute leakage and total inductances and define a relationship between them with different SR powers and high voltage levels. The expanded method is presented with the magnetic vector potential formulations.
