Application of orthogonal-core transformer to series compensation for power system

Kenji Nakamura; M. Kawakami; Mitsuru Maeda; Hiromichi Sato; O. Ichinokura

This paper presents an orthogonal-core type series compensator for a power flow control in an electric power system. The orthogonal-core type series compensator is constructed with the variable inductors using the orthogonal-cores and capacitors. For reduction of harmonic currents, the orthogonal-core utilizes wedge gaps and third windings. The orthogonal-core type series compensator is able to control the active power and its flow direction.
