Abstract
This paper presents analytical frequency domain method for harmonic modeling and evaluation of Space Vector Pulse Width Modulation (SVPWM) based static synchronous series converter (SSSC). SVPWM is the best among all the PWM techniques. It gives a degree of freedom of space vector placement in a switching cycle. Dynamic modeling technique is used for space vector modulation (SVM) based voltage source converter that is adapted as a static synchronous series converter (SSSC) for harmonic analysis using dynamic harmonic domain. Performance of the SSSC is evaluated in dynamic harmonic domain simulation studies in MATLAB environment. The switching function spectra are necessary for harmonic transfer matrix which is calculated using Fourier series. This paper presents the analysis of harmonics for space vector based SSSC during steady state and dynamic condition.

Harmonic in power system caused by highly non-linear devices degrades its performance
Due to recent development in the semiconductor technology and availability of high power switches e.g. Insulated Gate Bipolar Transistor (IGBT) and Gate Turn Transistor (GTO) have widespread acceptance in for high power Voltage Source Converter (VSC)’s, which are used for flexible AC transmission system (FACTS) controllers
To extend the results obtained by other authors in the modeling of synchronous series converter (SSSC) FACTS device, the proposed Space Vector Pulse Width Modulation (SVPWM) VSC based SSSC model is developed in order to be able to obtained the evolution in the of harmonic components of the SSSC signal
Summary
Harmonic in power system caused by highly non-linear devices degrades its performance. One attracting method for modeling the steady state performance of these devices is frequency domain analysis [1]. Second method is more suitable for calculation of instantaneous power quality indices, protection analysis and real time application all through it is violating causality and spurious dynamics result provided enough harmonic consideration [3]. To extend the results obtained by other authors in the modeling of SSSC FACTS device, the proposed SVPWM VSC based SSSC model is developed in order to be able to obtained the evolution in the of harmonic components of the SSSC signal. This paper presents the dynamic analysis of SVPWM based SSSC during steady state and dynamic condition. This gives the information about harmonic indices during transient condition . The fourth section deals with DHD modeling of SVPWM VSC used for SSSC
