An Improved Nonlinear STATCOM Control for Electric Arc Furnace Voltage Flicker Mitigation
Abstract
Electric arc furnaces (EAFs) are prevalent in the steel industry to melt iron and scrap steel. EAFs frequently cause large amplitude fluctuations of active and reactive power and are the source of significant power-quality (PQ) disturbances. Static synchronous compensators (STATCOMs) provide a power-electronicbased means of embedded control for reactive power support and PQ improvement. This paper introduces a new nonlinear contr ....etc

Abstract
In this paper, the mathematical model of
STATCOM based on space vector theory is presented. The
voltage equations are transformed into the synchronous rotating
reference frame (dq-axis). The relationship between STATCOM
parameters and stability, transient and steady state
performances are determined. Stability investigation with Routh-
Hurwitz criterion indicates that the STATCOM is a stable
system and the numerical values of resistors, inductors and
capacitors in the STATCOM equivalent circuit have no effect on
stabil ....etc

ppt on voltage flicker compensation using STATCOM

Voltage flicker is considered as one of the most severe power quality problems (especially in loads like electrical arc furnaces) and much attention has been paid to it lately. Due to the latest achievements in the semiconductors industry and consequently the emergence of the compensators based on voltage source converters, FACTS devices have been gradually noticed to be used for voltage flicker compensation. This paper covers the contrasting approaches; dealing with the voltage flicker mitigat ....etc

In this seminar a method for wideband harmonic compensation is presented. The main circuit configuration of the system is shown in Fig. 2. The system compensates the low order harmonics using a simple computational control delay compensation method, while the high order harmonics are filtered with a small passive high pass filter. In the system the whole filtering band of the APF is utilized and the filtering performance is recovered with an HPF when the ability of the APF to filter harmonics effectively is impaired. This way the size of the pa ....etc

reactive power compensation using d statcom ppt

Abstract

We present a solution to the problem of reactive power compensation and harmonic compensation in a general case when both the source voltages and the load currents are unbalanced and contain an arbitrary number of harmonics. For the compensation purpose, a d-statcom is connected in parallel to inject the required currents, so that from the source terminals the same apparent resistance is observed in all phases and at all frequencies. A controller based on the ideas of passivity theory, ....etc

Abstract
STATCOM can provide fast and efficient reactive power support to maintain power system voltage stability. In the literature, various STATCOM control methods have been discussed including many applications of proportional-integral (PI) controllers. However, these previous works obtain the PI gains via a trial-and-error approach or extensive studies with a tradeoff of performance and applicability. Hence, control parameters for the optimal performance at a given operating point may not be effective at a different operating point. This p ....etc
