Title: Damping Control with FACTS Aiming at Damping Inter-area Oscillation
Abstract: Electromechanical oscillations are composed of local oscillation and inter-area oscillation. With the development of electric power systems, inter-area oscillation has been a major concern. Inter-area oscillation, which aroused by many generators in different areas, will not be damped effectively if only a few generators install power system stabilizer which could be very effectively to damp local oscillation, while flexible ac transmission system(FACTS) may have a good effect because of its installing flexibly and good dynamic performance. So FACTS is used to damping inter-area oscillation in this paper. With the developing of power electric, FACTS have a good progress, and are used widely in power system. In this paper, four kinds of FACTS are introduced while their models are based in power system analysis software package(PSASP). The power in area oscillation is constant in non-damping power system, which is testified in this paper. So a damping controller of FACTS is designed with the theory of deducing the power in area oscillation. In this paper, SVC is taken for example to design the damping controller, and proved the effect by simulation in PSASP. Damping controllers of other kinds of FACTS including TCSC, STATCOM and SSSC are also designed, which also have good effect to damping inter-area oscillation by simulation. The power oscillation between two areas is damped quickly while these FACTS are installed. The results indicated that it is effective to damp the inter-area oscillation through FACTS.
