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 compensator protection

IEEE Transactions on Power Delivery, 1995
Static VAr compensator (SVC) protection practices are presented. Protection schemes comprise a combination of conventional protective relays as well as protection functions performed by the control system. This paper describes different protection functions applicable to SVCs and includes a tabulated overview of possible SVC protection methods.

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), 2019
The 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 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.
