   Mitigation of Unbalance Voltage Sag with Phase Jumps by UPQC with Minimum Real Power Injection
By Siva Kumar G, Kalyan Kumar B, Mahesh K MISHRA [View]
[Download]

Abstract: In this paper, a new methodology is proposed to mitigate unbalanced voltage sag with phase jumps by Unified Power Quality Conditioner (UPQC) with minimum real power injection. Particle Swarm Optimization (PSO) has been used to find the solution of the objective function derived for minimizing real power injection of UPQC along with the specified constraints. The proposed method is validated through detailed simulation studies.

   Modified four leg DSTATCOM Topology for Compensation of Unbalanced and Non linear loads in Three Phase Four wire System
By Nagesh GEDDADA, Srinivas Bhaskar KARANKI, Mahesh Kumar MISHRA, Kalyan Kumar B [View]
[Download]

Abstract: This paper proposes a modified four leg Distribution Static Compensator (DSTATCOM) topology forcompensation of unbalanced and nonlinear loads in three phase four wire system. This proposed modifiedtopology uses a capacitor connected in series with the interface inductor at the point of common coupling(PCC). This Modified topology requires a lower value of dc link voltage (Vdcre f ) across the dc storagecapacitor of voltage source inverter (VSI) for compensation of source currents, when compared with thebasic four leg DSTATCOM topology. The reference filter currents are generated using instantaneoussymmetrical component theory and are tracked using hysteresis current control technique. A detailedsimulation study to compare the performances of basic and modified topologies are carried out usingPSCAD 4.2.1.

   Simulations of a Current-Source Shunt Active Power Filter with Carrier-Based PWM and Periodic Sampling Modulation Techniques

Abstract: This paper presents a Shunt Active Power Filter that is built using a current-source inverter. The control of the Active Filter relies in the p-q Theory with the “Sinusoidal Currents at Source” algorithm implemented. The Active Power Filter was simulated using two modulation techniques: Periodic Sampling and Carrier-Based Pulse Width Modulation (CBPWM). To assess the performance of the Active Filter, the simulations were made using two different loads. The first load was a RL balanced load. The second was a non-linear load, namely a full bridge rectifier with a RL load in the DC side. These loads allowed determining the performance of the Active Filter when compensating current harmonics and power factor, using the two modulation techniques.
