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.

Novel four-bridge PWM static VAr compensator

IEE Proceedings - Electric Power Applications, 1997
A novel four-bridge PWM static VAr compensator is presented. Theoretical analysis shows that the harmonic pairs of [(2k + 1)fs ± f] and [(4k + 2)fs ± f)] generated in each bridge are effectively eliminated through appropriate phase shift control. To satisfy the same 5% total harmonic distortion requirement, this new compensator can work at 200 Hz ...

Series-type solid-state static VAR compensator

IEEE Transactions on Power Electronics, 1993
A fast response, electronically controlled, continuously variable, equivalent capacitive reactance for series compensation of a utility transmission line is described. Unlike compensation by series dielectric capacitors, there is no fear of subsynchronous resonance (SSR) instability.

A three-level advanced static VAr compensator

IEEE Transactions on Power Delivery, 1996
An advanced static VAr compensator (ASVC) employing a three-level inverter has been investigated for three-phase applications. The paper describes the operating principles of the ASVC using an elementary single phase ASVC circuit. The construction of a hardware model of the three-phase, three-level ASVC is then presented. The performance of the ASVC is

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.

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 ...

Self‐tuning control of static var compensators

Electrical Engineering in Japan, 1989
On elabore un modele de perturbation d'energie reactive a partir d'un four a arc comme charge d'une alimentation alternative triphasee. Pour cela on realise des simulations analogiques a l'aide d'une structure de commande d'allumage du type retroaction, comprenant une inductance commandee par thyristor.

Static VAR compensator using recurrent neural network

Electrical Engineering, 2013
In this paper, an internal model control recurrent neural network method is used to control the switching of thyristor-controlled reactor in a static VAR compensator (SVC) system for regulating the voltage. The novel controller scheme contains several feedback loops instead of only a feed-forward loop as in the conventional recurrent neural network ...

Modelling a static VAr compensator using EMPT

38th Midwest Symposium on Circuits and Systems. Proceedings, 2002
A digital simulation of a static VAr compensator (SVC) using a thyristor controlled reactor (TCR) and fixed capacitor (FC) is presented. This configuration is widely used in power system applications. The model is tested under EMTP (ATP version).

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
