SSSC's Adaptive Neural Control

The 2006 IEEE International Joint Conference on Neural Network Proceedings, 2006
The aim of this paper is to present the control of a solid-state series compensator (SSSC) by a B-spline neural network (NN) in order to regulate the active power flow on a transmission line. Such control drives the phase of the series source to the desired value so as to achieve the reference power flow.

Control algorithm for a SSSC

2009 Compatability and Power Electronics, 2009
The power grid in most of the countries is aging and under increasing stress. The modern industrial infrastructure demands increasing amounts of affordable and reliable electricity. Solutions based on Flexible AC Transmission Systems (FACTS) can be used to control power flow on the grid.

SSSC switching functions model

IEEE Transactions on Power Delivery, 2006
This letter proposes a static synchronous series compensator switching functions model based on a 48-pulse voltage-source inverter in abc coordinates. The effectiveness and accuracy of the model are validated against simulations carried out in the professional computer program PSCAD/EMTDC.

VSC-HVDC Station With SSSC Characteristics

IEEE Transactions on Power Electronics, 2004
Commercial installations of voltage-source converter-high voltage direct current (VSC-HVDC) are now in service as asynchronous link and as underwater/underground DC transmission. The research reported in his paper is directed to providing VSC-HVDC with synchronizing power and damping power so that after a transient the steady-state is reached in ...

Modeling of SSSC with EMTP RV

2006 IEEE International Symposium on Industrial Electronics, 2006
This paper presents the model of a Static Synchronous Series Compensator with the simulation package EMTP RV. The model uses a neutral point clamped (NPC) voltage source converter (VSC) to generate a high quality waveform. The model operation is verified with two types of controllers: Direct and Indirect to validate their mode of operation.

Modeling of SSSC in harmonic domain

2007 42nd International Universities Power Engineering Conference, 2007
In this paper a linear model for SSSC1 in harmonic domain is presented. In this model the harmonic voltages that SSSC injects in to the power system can be calculated. It is assumed that SSSC uses a 6-pulse PWM converter. The third harmonic is assumed to be eliminated by conducting angels of the switching functions equal to 120 degrees.
