A New Static Var Compensator for an Arc Furnace

IEEE Transactions on Power Systems, 1986
This paper presents the design of an electronic compensator that can compensate the reactive current drawn by an arc furnace. Consisting of three independent single-phase pulse-width modulated (PWM) inverters, the proposed compensator responds quickly to any sudden load changes and compensates both the fundamental displacement current and the harmonic ...

A Static Var Compensator Using a Superconducting Coil

IEEE Transactions on Power Apparatus and Systems, 1982
A superconducting coil has virtually no losses for a dc current. To utilize this feature in a static VAR compensator application the conventional conversion equipment between the three phase system and the coil must be modified to obtain variable ac currents with a constant coil current.

Power flow models of static VAR compensator and static synchronous compensator

2012 IEEE Fifth Power India Conference, 2012
Power flow models for static VAR compensator (SVC) and for the static synchronous compensator (STATCOM) are presented in this paper. The SVC model incorporates both the representations — the variable shunt susceptance as well as the firing angle as the state variables.

A Practical Control Strategy for Hybrid Static Var Compensator

2021 20th International Symposium on Communications and Information Technologies (ISCIT), 2021
This paper proposes a simple and practical control strategy for the previously proposed hybrid static var compensator (SVC). The source-side currents are not detected, and the electric angle of the receiving-end voltage is also not calculated in the proposed control strategy.

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

Utility Application of Static Var Compensation

Proceedings of the 1987 IEEE Southern Tier Technical Conference, 1987., 2005
The Marcy South Project, 200 miles of 345KV (kilovolts) transmission lines, is-being constructed to permit the cost-effective north-south transfer of low cost hydro-produced power from Canada, downstate to New York City by 1988. This project has involved new and interesting technology in its design and construction.

Refurbishment of the static VAr compensator at Laurentides

2003 IEEE Power Engineering Society General Meeting (IEEE Cat. No.03CH37491), 2004
This paper provides a case study of the refurbishment of a 1978 SVC at Laurentides. A historical overview of the operating experience is provided with an evaluation of the state of the equipment prior to refurbishing. A full description of the justification to extend life at a minimum cost is given. Finally, a retrospective of the key technical aspects

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
