Hexagram converter for static VAR compensation

2008 IEEE/PES Transmission and Distribution Conference and Exposition, 2008
A new multilevel converter - Hexagram converter is proposed for static VAR compensation in high-voltage high- power applications. The new converter is composed of six three- phase two-level standard voltage source converter (VSC) modules interconnected through inductors.

Laboratory realization of a Static VAr compensator

2013 International Conference-Workshop Compatibility And Power Electronics, 2013
In a low voltage distribution network, wisely applied local reactive power generation can improve voltage profiles and reduce loses related with the energy transmission. This paper deals with the laboratory realization of a Static VAr compensator (STATCOM) suitable for adjustable local reactive power generation. In the case study, the basic design of a

Nonlinear control for static VAR compensator

Proceedings of TENCON '93. IEEE Region 10 International Conference on Computers, Communications and Automation, 2002
A nonlinear control design approach based on differential geometric control theory is presented briefly. It is taken the nonlinearity of a power system with static VAR compensator (SVC) into account by the mathematical model of the system for the SVC controller design.

A novel concept for static VAR compensators

2013 IEEE 8th International Conference on Industrial and Information Systems, 2013
A new configuration to replace the Thyristor Controlled Reactor (TCR) of a Static VAR Compensator (SVC) by a DC link voltage controlled inductor is proposed in this paper. In this proposed technique, the reactor current contribution is regulated by controlling the peak current through the reactor which conducts for a complete cycle. This is in-contrast

Static VAr compensation system for industries

Power Quality '98, 2002
Industrial power supply networks today are polluted by various loads connected to them and their method of control. Consumers are required to meet the stringent requirements imposed by electric utility authorities at the supply network. Hence, it is very much essential for industrial plants to have a static VAr compensator (SVC) for both reactive volt ...

Equivalent Circuit for Frequency Response of a Static Var Compensator

IEEE Transactions on Power Systems, 1986
A model at harmonic frequencies is developed for a static VAR compensator. The model consists of a harmonic voltage source in series with a variable source admittance. The model is shown to be useful in predicting resonance problems using digital simulation.

Static VAr compensators in the Malaysian grid

Conference Record of the Power Conversion Conference - Yokohama 1993, 2002
The National Power Corporation (TNB) have ordered and placed into operation three static VAr compensation systems (SVCs) at its Kuala Lumpur North (KLN) and Yong Peng (YP) substations. The project was commissioned in the middle of 1991, and over the last one and a half years, TNB have gained considerable experience in operation and maintenance of the ...
