This paper investigates the role of Static Var Compensator (SVC) on stability of voltage in grid system due to the presence of harmonics.. Here the design of SVC is based on the combination of Thyristor switched capacitors (TSC’s) and Thyristor controlled reactor (TCR) . TSC’s are used for switching the capacitor banks on and off while the TCR continuously controls the reactive power by varying...

Voltage stability analysis is essential for a secure power system operation.This study demonstrates the use of latest Power System Analysis Toolbox (PSAT) package for network analysis of alternative means of improving existing transmission system voltage stability. This project presents the investigation on steady state voltage stability improvement by determination of best location of Flexible...

In this paper presents a fast new PI controlled DSTATCOM used to compensate for harmonic distortion in threephase system. The DSTATCOM employs a simple Method for the calculation of the reference compensation current based. The presented DSTATCOM is able to operate in balanced, unbalanced and Variable load conditions. Classic filters may not have satisfactory performance in fast varying conditi...

In the previous studies the effect of Static Var Compensator (SVC) and Power System Stabilizers (PSS) has not been considered specially for various faults in a three phase system. For improvement in inductive and capacitive power flows Shunt Flexible AC Transmission System (FACTS) devices can be used and when they are placed in the center of transmission line of a electrical power transmission ...

Encountering series-compensated transmission lines, sub-synchronous resonance (SSR) may strike the power system by jeopardizing its stability and mechanical facilities. This paper aims to verify the capability of static synchronous series compensator (SSSC) in mitigating the mechanical and electrical oscillations such as SSR in wind farm integrations. A wind turbine with a self–excited inductio...
