AN ADAPTIVE POWER SYSTEM STABILIZER
IFAC Proceedings Volumes, 1987Abstract The evolution of the adaptive control concept in which a controller continuously tunes itself to the changing plant characteristics, has provided an attractive design alternative to the conventional approach. A microcomputer based power system stabilizer using the self-tuning adaptive control concept is described in this paper. The recursive

AN ADAPTIVE POWER SYSTEM STABILIZER
IFAC Proceedings Volumes, 1988This paper presents an adaptive power system stabilizer utilizing the eigenvalue control strategy. The control algorithm is based on the identification of decoupled subsystem model parameters in real-time from local measurements only. The concept of decentralized stabilization of power system electromechanical oscillatory modes is discussed and control

The goal of this project, part of the Power Industry Consortium, was to design a power system stabilizer for a small grid-connected three phase synchronous generator. Power System Stabilizers control the excitation of synchronous generators to reduce lowfrequency oscillations on the grid and increase overall power system stability.

Improving dynamic stability of power system using derivative power system stabilizer
2016 13th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON), 2016The main function of power system stabilizer (PSS) is suppressing the low-frequency oscillation of the power system to improve the dynamic stability of power system. In this paper, the pole-placement approach and full phase-compensation method are used to design the parameters of a derivative power system stabilizer (DPSS) base on electrical torque ...

Monitoring power system stability
IEEE Computer Applications in Power, 1989A description is given of Utah Power & Light's transient stability monitoring system, a system that monitors the parameters of stability quickly enough to assist in guarding against transient (sudden and major) instabilities. A system overview is given, followed by a discussion of the encoders, decoder, real-time displays, postmortem displays, and ...

Robust power system stabilizer
2001 IEEE Porto Power Tech Proceedings (Cat. No.01EX502), 2002This paper presents the development of /spl mu/-power system stabilizer (PSS) based on the active power measurement to enhance damping characteristics of the single-machine infinite-bus system. The standard design procedure of the PSS requires the nominal structured model to be formulated. It is obvious that this linearized model loses some information

Power System Voltage Stability
2020Understanding the voltage instability phenomenon and its effects in detail facilitates the research community to develop methodologies that can detect instability in a timely manner. Traditionally voltage instability in the system is identified through P-V and Q-V curves that are plotted using repetitive runs of load flow programs.
