This paper discusses the incorporation of a Superconducting Magnetic Energy Storage (SMES) coil into a voltage source inverter based static synchronous compensator (StatCom) in damping dynamic oscillations in power systems. A 100 MJ 96 MW (peak) SMES coil is attached to the voltage source inverter front end of a 160 MVA StatCom via a dc-dc chopper. The performance of the StatCom, a self-commuta...

This paper presents a study of a D-STATCOM (Distribution Static Compensator) used for mitigating voltage sag. The basic idea of the voltage sag mitigation, using a D-STATCOM is to dynamically inject a current of desired amplitude, frequency and phase into the grid line. The proposed method extracts the active and reactive parts of the positiveand negative-sequence component for generating refer...

The optimal placement of STATic synchronous COMpensator (STATCOM) for voltage stability improvement in power system is the important optimization problem. There are so many research works are carried out in the optimal placement of STATCOM to achieve the various objectives using Particle Swarm Optimization (PSO). In conventional optimization technique the weight-age of objective functions are c...

This paper introduces an approach to detect the existence of the faulted switch, identify which switch is faulty, and reconfigure the STATCOM. This approach is illustrated on an elevenlevel STATCOM and the effect on the dynamic performance and the total harmonic distortion (THD) is analyzed Many static synchronous compensators (STATCOMs) utilize multilevel converters due to the following: 1) lo...

This paper introduces a multilevel STATCOM for electric arc furnace power quality enhancement. An eleven level cascaded multilevel converter is used to alleviate the impacts of an unbalanced arc furnace load. The STATCOM provides a power electronic-based means of embedded control for reactive power support.

facts technology has considerable applications in power systems, such as; improving the steady stateperformance, damping the power system oscillations, controlling the power flow, and etc. statcom is oneof the most important facts devices used in the parallel compensation, enhancing transient stability andetc. since three phase fault is widespread in power systems, in this paper statcom is used...
