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

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 ...

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

Performance Analysis Of A SSSC-Based Damping Controller

Michael Faraday IET International Summit 2015, 2015
This paper deals with the performance analysis of a damping controller for a Static synchronous series compensator (SSSC) for enhancing the power system dynamic stability of a single machine power system connecting to an infinite bus. Following a disturbance in the power system, there will be a miss-match between the input mechanical and output ...

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

Design and performance evaluation of subsynchronous current suppressor with SSSC

TENCON 2009 - 2009 IEEE Region 10 Conference, 2009
A long transmission line needs controllable series as well as shunt compensation for power flow control and voltage regulation. This can be achieved by suitable combination of passive elements and active FACTS controllers. In this paper, series passive compensation and series active compensation provided by a static synchronous series compensator (SSSC)
