Monitoring and Estimation of Interarea Power Oscillation Mode Based on Application of Campuswams
نویسندگان
چکیده
Based on application practices of the CampusWAMS developed in Western Japan 60-Hz power system and Thailand power system, this paper presents a single-mode-oriented monitoring and estimation scheme of power system small-signal stability. The data filtering technique based on FFT is employed to extract oscillation data for single mode. The auto spectrum analysis is employed to compute the dominant frequency of oscillation mode, which is used to set filter frequency band. An output-only-based simplified oscillation model is developed to estimate the characteristic of interarea power oscillation based on extracted oscillation data. Finally, some analysis results on Western Japan 60-Hz power system and Thailand power system based on measured phasor data illustrate the validity of developed methods and techniques.

A Robust FACTS Damping Controller Design to Mitigate Interarea Oscillations in a Multi-machine Power System
In this paper, damping of interarea oscillations using simultaneous coordination of static Var compensator (SVC) and power system stabilizer (PSS) is considered. To be effective in damping of oscillations, the best-input signal of power oscillation damper (POD) associated with SVC is selected using Hankel singular values (HSVs), and right-hand plane zeros (RHP-zeros). The 4-machine-2 area...

This paper introduces a new nonlinear control of flexible ac transmission systems (FACTS) controllers for the purpose of damping interarea oscillations in power systems. FACTS controllers consist of series, shunt, or a combination of series-shunt devices which are interfaced with the bulk power system through injection buses. Controlling the angle of these buses can effectively damp low frequen...
