An improved web information summarization based on SSSC

2010 2nd International Asia Conference on Informatics in Control, Automation and Robotics (CAR 2010), 2010
This paper proposed a new method of web news summarization via soft clustering algorithm. It used search engine to extract relevant documents, and mixed query sentence into sentences set which segmented from multi-document set, then this paper adopted efficient soft cluster algorithm SSSC to cluster all the sentences.

Design and analysis of SSSC-based supplementary damping controller

Simulation Modelling Practice and Theory, 2010
Abstract Power-system stability improvement by a static synchronous series compensator (SSSC)-based damping controller is thoroughly investigated in this paper. The design problem of the proposed controller is formulated as an optimization problem, and real coded genetic algorithm (RCGA) is employed to search for the optimal controller parameters ...

Novel reactive power controllers for the STATCOM and SSSC

Electric Power Systems Research, 2006
Abstract The paper investigates the dynamic operation of both static synchronous compensator (STATCOM) and static synchronous series compensator (SSSC) based on a new model comprising full 48-pulse GTO voltage source converter for combined reactive power compensation and voltage stabilization of the electric grid network.

Effects of statcom, sssc and upfc on voltage stability

Thirty-Sixth Southeastern Symposium on System Theory, 2004. Proceedings of the, 2004
The purpose of this paper is to study the effects of three FACTS controllers: STATCOM, SSSC and UPFC on voltage stability in power systems. Continuation power flow, with accurate model of these controllers, is used for this study. Applying saddle node bifurcation theory with the use of power system analysis toolbox (PSAT), the optimal location of these

Modular SSSC for the future power system in the SEERC region

European Energy and Climate Journal, 2021
Recently, the world has seen disruptive innovation and change regarding the ways that energy is produced and consumed. The power industry is facing systemic challenges in planning and operation of the whole system. Particularly, high penetration levels of Renewable Energy Sources (RES) bring additional design considerations due to their variable nature

Effects of SSSC on Distance Relay Tripping Characteristic

2006 IEEE International Symposium on Industrial Electronics, 2006
This paper presents the measured impedance at the relaying point in the presence of one of the series connected flexible alternating current transmission system (FACTS) devices, i.e. static synchronous series compensator (SSSC). The presence of SSSC on a transmission line greatly influences the tripping characteristic of distance relays. Distance relay

Harmonic Modeling of multi-pulse SSSC

2009 IEEE Bucharest PowerTech, 2009
The aim of this paper is to propose a Dynamic Harmonic Domain model for a 24-pulse Voltage Source Converter based Static Synchronous Series Compensator. The model is developed converting a state-space system to the Dynamic Harmonic Domain, having the advantage over Time Domain models of showing the evolution in time of the harmonic components that ...

A combined multipulse-multilevel inverter based SSSC

2009 International Conference on Power Systems, 2009
In this paper a new combined multipulse-multilevel inverter topology is proposed for the static synchronous series compensator to regulate power flow over the line. A closed loop controller for operating the SSSC in the automatic power flow control mode is developed. To analyze the performance of the SSSC connected in series with the transmission line,

Switching-level simulation model for SSSC with EMTP

IEEE Power Engineering Society. 1999 Winter Meeting (Cat. No.99CH36233), 1999
This paper describes a switching level simulation model for a static synchronous series compensator (SSSC) with EMTP, which can be useful for analyzing the dynamic interaction between the SSSC and the power transmission system. A detailed simulation model with EMTP was developed to verify the SSSC operation with control system, and the increasing ...

Robust control of SSSC to improve torsional damping

2001 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat. No.01CH37194), 2002
In this paper, the H/sub /spl infin// optimal control theory has been used to design a robust controller for regulating DC link voltage of a static synchronous series compensator (SSSC). Subsynchronous resonance (SSR) analysis of the robust SSSC compensated power system is presented. The power system used in this study is the IEEE first benchmark model
