Thyristor-controlled series capacitor (TCSC) as one of the most important FACT devices can be used for various purposes such as reactive power compensation, voltage control, dynamic stability improvement and power oscillation damping in power systems. Practical aspects on sizing of TCSC elements must be considered to have the fast and reliable switching from capacitor to inductive region and vi...

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...

This paper introduces a fuzzy PI controller as a power system stabilizer. The fuzzy PI controller has been designed to prepare an auxiliary signal to the excitation system of the synchronous generator. The proposed controller utilizes a combination of a fuzzy logic controller (FLC) and a PI controller. In comparison with the conventional fuzzy controllers, the proposed fuzzy PI controller incor...

Galileo noted in the 16 century that the period of oscillation of a pendulum is almost independent of the amplitude. However, such a pendulum is damped by air friction. The latter may be viewed as resulting from air molecules getting in contact with the pendulum. It follows that air friction, not only damps the oscillation, but also introduces randomness. In the so-called “grand-mother” clock, ...

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...

Both fixed-speed squirrel-cage induction generators and variable-speed doubly-fed induction generators are used in wind turbine generation technology. Modeling and simulation of induction machines using vector computing technique in Matlab/Simulink provides an efficient approach for further research on wind generation system integration and control. In this paper, the vector computing technique...
