VOLTAGE SOURCE CONVERTER TOPOLOGY FOR HVDC GRID CONNECTION OF OFFSHORE WIND FARMS
ABSTRACT
Large offshore wind farms are recently emerging as promising alternative power Sources. Long distances between offshore generation and onshore distribution grid demand new solutions for their connection to the AC network. HVDC systems based on voltage source converters (VSC) are a promising alternative to conventional AC transmission above a certain cable length. This paper p ....etc

A High Input Voltage Three-Phase ZVZCS DC-DC Converter with Vin /3 Voltage Stress on Primary Switches
Abstract
A high-voltage three-phase ZVZCS dc-dc converterwith low voltage stress is presented in this paper. The voltagestress on the primary switches is only one-third of the inputvoltage. By using the phase shift pulsewidth modulation (PWM)and secondary snubber, four of the six primary switches areoperating with zero-voltage switching (ZVS) and two of them areoperating with zero-current switching (ZCS), in order to reducethe switch ....etc

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 cont ....etc

Static VAr Compensation with a voltage source converter

abstract
Electrical utilities and heavy industries face a number of challenges related to reactive power. Heavy industrial applications can cause phenomena like voltage unbalance, distortion or flicker on the electrical grid. Electrical utilities may be confronted with phenomena of voltage sags, poor power factor or even voltage instability. Reactive power control can resolve these issues. ....etc

Study of Evaluated a STATCOM Application for Voltage Stability by Dynamic PV Curves and Time Simulations
Abstract:
In this paper; voltage stability is evaluated by both
dynamic PV curves and titne-domain simiilations. considering the
combined a'ynamic contsol effects of a static compensator
(Sl:4TCOA.I) and transfosnier on-load-taps (OLT). The studied
system is heavily loaded at hvo locations and an 80 Mvar
SPITCOM is connected to impsore the voltage stability of entire
system for a contingency of a three-tesminal line o ....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
stabi ....etc
