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.

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.

Multi-step static VAr compensators analysis

IEEE Power Engineering Society Summer Meeting,, 2003
Since the concept of FACTS was introduced, a new family of power electronic equipment has emerged for controlling and optimizing the performance of power systems, e.g. STATCOM, SSSC and UPFC. The use of voltage-source inverter (VSI) has been widely accepted as the next generation of reactive power controllers to replace the conventional VAr ...

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.

Clapham static VAr compensator control retrofit

IEEE Transactions on Power Delivery, 1998
The performance of the Clapham SVC after a control retrofit is described. The replacement of an analogue with digital control was completed in 1995. The retrofit was accomplished well within the ten days of allotted shut down time. With the original control system, AC system voltage unbalance caused by untransposed lines had to be balanced by manual ...

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.

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.
