This paper introduces a control algorithm for generation of reference voltages based on single-phase SOGI (Second Order Generalized Integrator) for DVR (Dynamic Voltage Restorer). The proposed DVR is a series active compensator used for compensation of voltage sag and swell to the desired level. The proposed control algorithm is capable of generating reference voltages in sag, swell and phase jump...
This paper introduces an improved control algorithm based on single-phase SOGI (Second Order Generalized Integrator) for the generation of DSTATCOM (Distribution Static Synchronous Compensator) reference currents. In a distribution system, DSTATCOM serves as an optimal choice for power quality compensation. The power quality (PQ) compensation under adverse grid conditions and varying load conditions...
This paper introduces a control algorithm for generation of reference voltage and current based on single-phase SOGI (Second Order Generalized Integrator) for UPQC (Unified Power Quality Conditioner). The proposed UPQC is a combination of shunt and series active compensators used for load and source compensation such as voltage harmonics, current harmonics, sag and swell. The proposed control algorithm...
In this paper, a new Second Order Generalized Integrator - Phase Locked Loop control algorithm for reactive power compensation, load balancing, harmonic elimination and neutral current compensation is presented. The strategy is proposed for DSTATCOM to function under distorted load conditions and to improve the power quality at the supply mains. This control algorithm extracts the fundamental component...
