In this paper, a three-phase advanced static compensator (STATCOM) is proposed to compensate reactive power either for regulating ac supply voltage at a constant value or for unity power-factor and balancing of unbalanced reactive loads. An insulated gate bipolar transistor (IGBT) based current controlled pulse width modulated (CC-PWM) and voltage source inverter (VSI) is employed as the STATCO...

In this Space Vector PWM Control technique is designed for a three-phase voltage source converter (VSC) which act as a Static Synchronous Compensators to provide reactive power compensation. The VSC as STATCOM provide efficient damping for sub synchronous resonance that enhance the Power System Stability in addition to RPC. Among different Pulse width modulation techniques SVPWM technique is im...

The electric arc furnaces are a very large power load, determining the negative effects on the power quality (harmonics currents, unbalanced load, and reactive power). For a maximum efficiency of the power consumption it is necessary to use an automat system for control the harmonics filters, the reactive power compensation installation and the electrodes position, in order to obtain a high val...

Reports of various committees set up to review the 2003 North American major power outages pointed out that a major exacerbating factor has been lack of situational awareness by power system operators. To improve reactive power compensation and contribute to the mitigation of power outages associated with the present near-limit operated commercialized grid, a bus voltage stability (BVS) index b...

Due to the wide spread of power electronics equipment in modern electrical systems, the increase of the harmonics disturbance in the ac mains currents has became a major concern due to the adverse effects on all equipment. Power electronic converters are commonly used for interfacing distributed generation (DG) systems to the electrical power network. However, the unbalanced voltage compensatio...

This study presents the auxiliary damping control with the reactive power loop on the rotor-side converter of doubly-fed induction generator (DFIG)-based wind farms to depress the sub-synchronous resonance oscillations in nearby turbogenerators. These generators are connected to a series capacitive compensation transmission system. First, the damping effect of the reactive power control of the ...

Optimal reactive power flow is an optimization problem with one or more objective of minimizing the real power losses. The ancillary service for a generator has two components that have been recently recognized, i.e., one for sustaining its own real power communication and the other for providing reactive demand, enhancing system security, and scheming system voltage; and that only the next par...
