Problem statement: Static Synchronous Compensator (STATCOM) and Static Synchronous Series Compensator (SSSC) have been individually applied to improve stability of power system. Approach: This study presents the coordination of a STATCOM and SSSC for improving power system stability. The swing curves of the three phase faulted power system with various cases are tested and compared. Results: Th...

This paper proposes a flexible D-STATCOM (Distribution Static Compensator) and its new controller system, that be able to mitigate all types of faults (LG, DLG, LL, LLL and LLLG), and improve the distribution system performance. This paper validates the performance of D-STATCOM system to mitigate the power quality problems such as voltage flickers, voltage sags/swells harmonics and improve the ...

صخلملا The aim of this study isto examine whether radiofrequency (RF) used in cellular phone communications at a specific absorption rate (SAR) less than 1.2 w/kg could increase the spontaneous rate of sister chromatid exchanges (SCE) or elicit alterations both in the cell replication index (CRI) and mitotic index (MI) in human peripheral blood lymphocytes. Whole blood samples were obtained fro...

In emerging electric power systems, enlarged communication often lead to the situations where the structure no longer remains in secure operating region. The flexible Ac transmission system (FACTS) controllers can take part in an important role in the power system security enhancement. However, due to high capital investment, it is necessary to locate these controllers optimally in the power sy...

This paper presents an analysis of the three-phase self-excited induction generator (SEIG) with staticcompensator {STATCOM) as a voltage regulator. Current controlled voltage source inverter (CC-VSI) is used as STATCOM, which provides fast dynamic response to maintain constant voltage at SEIG terminals during severe load perturbations and acts as a source and sink of reactive power. The perform...

Original scientific paper The scope of this paper covers the investigations of discontinuous PWM (DPWM) control of the Distribution Static Synchronous Compensator (D-STATCOM). Various DPWM methods have been widely used in motor drives for controlling the inverter and reducing power losses. With the rising demand for energy, energy efficiency has currently become an issue of vital importance. As...

This work deals with modeling and simulation of multi bus system using D-STATCOM. Voltage sag is increased by connecting a heavy load. The sag is mitigated using D-STATCOM. The circuit models and simulation results are presented. The Simulation results are compared with the analytical results. KeywordsDistribution Static Synchronous Compensator (D-STATCOM)
