Harmonic Domain Modelling of Space Vector Based STATCOM

Abstract

This paper presents frequency domain method for harmonic analysis of space vector based STATCOM. Space Vector Pulse Width Modulation (SVPWM) method is an advanced PWM method. It is a best method among all the PWM techniques. It provides a freedom in a switching cycle for placement space vector. In this paper, the SVPWM is used for switching of STATCOM. The harmonic (or frequency) domain is a steady-state form of harmonic analysis method, which represents converters to their harmonic spectra. This paper presents harmonic analysis by means of harmonic domain for space vector based Static shunt converter (STATCOM). Performance of the STATCOM is evaluated in harmonic domain simulation studies in MATLAB environment.

Power Quality Enhancement in a Wind Farm Connected Grid with a Fuzzy-based STATCOM

“…The current produced due to sags/swells or flickers affects the switchgears and the protection system of the PCC. Therefore, various compensators with filters have been adopted to mitigate these power quality problems [9][10][11][12]. Many power quality conditioners have been implemented to address power quality issues in distribution networks, such as UPQC, DVR, and DSTATCOM [4,9,13,14].…”

“…Many power quality conditioners have been implemented to address power quality issues in distribution networks, such as UPQC, DVR, and DSTATCOM [4,9,13,14]. Among the different FACTS controllers, SVC and STATCOM play an important role in reactive power compensation [12,16]. In [8], two types of FACTS controllers, SVC and STATCOM, were considered to mitigate power quality issues.…”

“…However, it does not work on highvoltage transmission lines because the cost of APF is higher with multilevel structures. Some studies investigated the use of PI controllers [12]. Furthermore, controllers such as PI and PID require an intensive mathematical model of the system, making them more sensitive to changes in the system parameters [20].…”
