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...

in this paper, the performance of two types of facts devices in order to enhance the power system static voltage stability has been investigated. these devices include static var compensator (svc) and thyristor controlled series capacitor (tcsc). the modeling of the single machine infinite bus (smib) and aforesaid devices has been made up in steady state mode with disregarding of the generator ...

The transient stabilization and voltage regulation problem for a synchronous generator connected to an infinite bus is addressed, in this article, the presence of all uncertain physical parameters. First, new interpretations desensitized four loops regulator, here referred as robust coordinated power system stabilizer automatic regulator (PSS-AVR) are derived terms minimum phase properties with...

This paper presents a new approach for determining the effective control signals for damping of oscillations by performance comparison of Unified Power Flow Controller in coordination with Power Oscillation Damping Controller and Power System Stabilizer. For the analysis Modified Phllips-Heffron Model of Single Machine Infinite Bus system is established with Unified Power Flow Controller. Impac...

Power-system stability improvement by a static synchronous series compensator (SSSC)-based controller is studied in this paper. Conventionally, the lead-lag structure was used to modulate the injected voltage. But, in this paper PI, PID, PIDD structures are proposed to modulate the injected voltage. The design problem of the proposed controller is formulated as an optimization problem and Diffe...

In this paper a comparison of discrete time PID, PSS controllers is presented through small signal stability of power system comprising of one machine connected to infinite bus system. This comparison achieved by using a new approach of discretization which converts the S-domain model of analog controllers to a Z-domain model to enhance the damping of a single machine power system. The new meth...
