Stabilization of Longitudinal Power System by Means of Superconducting Magnetic Energy Storage

Abstract

A power system stabilization by means of the superconducting magnetic energy storage (SMES) has already been proposed, wherein the firing angle α of the SMES thyristor bridge is controlled, based on the angular velocity deviation ⊿ω of the generator rotor. In this paper, a simple longitudinal system is taken up as a sample system, and the optimum position of the SMES is investigated from the stabilizing point of view. Also studied is the effect of the distributed installation of the SMES from both sides of the steady-state stability by means of the eigenvalue method, and the transient stability by the simulation method.
