Static reactive-power (Var) compensators (SVCs) are finding wider use in both industrial and transmission system applications. In higher power industrial applications, static reactive-power compensators are a well established means of reactive-power control, especially for the reduction of voltage fluctuations caused by arc furnace loads. These systems are being applied to transmission systems to provide voltage regulation, reactive-power support, improved damping and an increase in system stability. This paper presents simulation results of a typical power system with a static reactive-power compensator of the thyristor-controlled reactor type. This static reactive-power compensator has linear optimal controller for the system stability. When the principle of linear optimal control is first applied to a power system, the main difficulty in design is the selection of the weighting matrices. This paper, therefore, presents the weighting matrices are decided automatically by an eigenvalue sensitivity.
