Abstract

SVC is a kind of FACTS device which is used in power system primarily for the purpose of voltage and reactive power control. Based on wide area signal, this paper presented a systematic approach for design of SVC supplementary control which is used to improve damping of power system oscillation. The principle of SVC damping oscillation is first analyzed and the concept of synthetic residue index is then presented which is used to choose the proper input wide area signals. Parameters of the controller are determined by means of test signal method and residue root locus. Eigenvalue analysis and time domain simulations were performed on a two-area system and the results demonstrated the effectiveness of the proposed controller
