This paper presents a self-organizing power system stabilizer (SOPSS) which use the fuzzy Auto-Regressive Moving Average (FARMA) model. The control rules and the membership functions of proposed the fuzzy logic controller are generated automatically without using any plant model. The generated rules are stored in the fuzzy rule space and updated on-line by a self-organizing procedure. To show t...

In this paper, transient stability improvement using bridge type fault current limiter (FCL) is presented in single machine infinite bus (SMIB) system with a double circuit transmission line. Three single-phase sets of the proposed FCL are installed at the beginning of feeder. The proposed FCL inserts an inductance and a resistance in the fault current pass. The insertion inductance and resista...

The present paper treats the rotor angle estimation problem in a singlemachine infinite bus setup. The components of the infinite bus voltage phasor are estimated in a coordinate frame that turns with the rotor by means of a Kalman-like filter from exclusively local measurements. Therefore, in addition to the rotor angle, the observer also provides an estimate of the infinite bus voltage. The p...

Transient stability problem for multi-machine infinite bus system with the generator excitation was addressed via the non-certainty equivalent nonlinear re-parameterization method. The system need not to be linearized. The damping coefficient uncertainty was considered. A non-certainty equivalent excitation controller and a novel parameter updating law were obtained simultaneously via adaptive ...

This paper presents a parameter modeling to Power System Stabilizers (PSS) using MLP and RBF neural networks. The application of neural networks in PSS aims to improve the dynamic stability of electric power systems by reducing the machine eletromechanic damping oscillation when a disturbance occurs. According to the current plant operating conditions, the PSS parameters are automatically adjus...

The paper presents the project to Power System Stabilizer applied to the generators of the gas turbines of Combined Cycle Power Station. The project developed used MATLAB software for the stabilizer’s parameters calculation. The calculation was gotten from the linear model based on a machine connected on an infinite-bus. The stabilizers had been used to increase the machine eletromechanic oscil...
