This Paper presents the orientation procedure for diagnosing the power quality problems in different fault occurring conditions by using Distribution STATCOM (DSTATCOM) with linear loads. Here the resistance switching is used to get the pure sinusoidal voltage compensation. This modelling and simulation of D-STATCOM is achieved by using pure sinusoidal Pulse Width Modulation Technique. The majo...

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...

A current source converter (CSC) based static synchronous compensator (STATCOM) is a shunt flexible AC transmission system (FACTS) device, which has a vital role in stability support for transient instability and damping support for undesirable interarea oscillations in an interconnected power network. A robust pole-shifting based controller for CSC-STATCOM with damping stabilizer is proposed. ...

Flexible ac transmission systems (FACTS) controller can provide better control than conventional control and achieve fast control response time. Static synchronous compensator (STATCOM) is one of the key FACTS devices based on voltage source converter (VSC) technology whose capacitive or inductive output current can be controlled independent of the ac system voltage. In this review paper, the a...

A delta-connected STATCOM with cascade multilevel full H-bridge (FHB) converter has been applied for phase balancing and power factor correction of unbalanced load in a three-phase, three-wire power distribution system. In this paper, a feedforward compensation formula is presented for the STATCOM by using the symmetrical components method to compensate unbalanced load. Computer simulation is p...

Fig. 1.1 Shows the circuit configuration for a 19-level (lineto-neutral) H-bridge StatCom (H-StatCom). Each stack ofH-bridges essentially forms one phase of a threephase currentcontrolledvoltage source. The purpose of the H-StatCom isto modulate the voltage at the output of each stack so thatthe current through the inductors can be controlled to providepower factor correction, compensate for sy...

In this paper, an optimal power flow based approach has been applied for multi-transactions deregulated environment for ATC determination with SVC and STATCOM. The main contribution of the paper is (i) OPF based approach for evaluation of ATC with multi-transactions, (ii) ATC enhancement with FACTS devices viz.

The objective of this paper is to investigate the enhancement of damping the low frequency oscillations via tuning of static synchronous compensator (STATCOM) damping controller. The problem of STATCOM based damping controller is formulated as an optimization problem according with the time domain-based objective function which is solved by a quantum-behaved particle swarm optimization (QPSO) t...

Voltage control and fast reactive power compensation are two main application area of Static Synchronous Compensator (STATCOM), which is a shunt connected voltage source converter (VSC) based FACTs controller using power semiconductor devices (particularly IGBT, GTO etc.).However, the total Statcom circuitry has complex and coupled system dynamics which require advanced controllers to achieve w...

Static Synchronous Compensator (STATCOM) is a device capable of solving the power quality problems at the power system. These problems happen in milliseconds and because of the time limitation, it requires the STATCOM that has continuous reactive power control with fast response. In this way, optimal exploitation of STATCOM by classical controllers has been a controversial issue in reputable jo...
