Nonlinear control for static VAR compensator
Proceedings of TENCON '93. IEEE Region 10 International Conference on Computers, Communications and Automation, 2002A 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.

Designing of static VAR compensators with voltage regulators
2019 IEEE International Conference on Environment and Electrical Engineering and 2019 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2019The approach to the designing of controlled reactive power compensators with AC sinusoidal voltage regulators is presented. Different topologies of VAR compensators with voltage regulators are analyzed. An example of sinusoidal voltage regulator realization based on a transformer with a controlled transformer ratio is considered.

A Static Var Compensator Using a Superconducting Coil
IEEE Transactions on Power Apparatus and Systems, 1982A 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, 1997A 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, 1993A 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, 1996An 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., 2005The 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.
