This paper proposes a hybrid control algorithm to maximize utilization and functionality of distribution static compensator (DSTATCOM). This control algorithm combines the different aspects of DSTATCOM operation and tries to mitigate the voltage and current harmonics, balance the source currents, improve the power factor, compensate for voltage disturbances such as sag and swell, reduce the losses...
This paper presents a proposal for a new algorithm and a modification for variant of delta modulation technique that is used for generating the control signals for main devices of PWM converters. Moreover, modeling and a simulation is developed for this modified variant of delta modulation technique. The effect of this algorithm is tested by using the developed simulation of quasi-stationary states...
This paper presents a novel control method for PWM boost rectifier based on instantaneous power. Unlike most of the existing control strategies implemented in synchronous or p-q (active-reactive power) frame, the proposed method can provide unity power factor on the AC side in stationary frame. Rotating transformation and phase detection are eliminated, offering a very simple solution. Based on the...
The principles and technologies of var compensation implemented with static capacitors, static Var compensator and static Var generator are concisely presents. The simulation and study for these methods are made. These methods' merits and faults are also compared through the wave analysis after simulation. It is shown the SVG is even more advantageous to dynamically improve voltage regulation, stability,...
