DC bus imbalance in a three phase four wire grid connected inverter
DC bus imbalance in a split capacitor based rectifier or inverter system is a widely studied issue. In this paper the DC bus imbalance problem has been studied for a three phase four wire grid connected inverter where the midpoint of the split capacitor is connected to the neutral of grid. The problem has been analysed from common mode point of view and subsequently a low frequency common mode ...
متن کاملA Novel Control Strategy for a Single-phase Grid-connected Power Injection System
In this paper, a novel and simple control strategy, based on state feedback method is suggested to control the power injection system (PIS). The considered PIS is composed of, a DC voltage source, a voltage source inverter (VSI) and a L-C-L filter. The DC source includes the battery source with boosted voltage. The battery can be charged with photovoltaic cells. Since, the grid voltage acts as ...
متن کاملA Reference Compensation Current Control Strategy for Grid-Connected Inverter of Three-Phase Distributed Generators
Renewable energy resources (RES) are being increasingly connected in distribution systems by utilizing power electronic converters. However, the extensive use of power electronics has resulted in a rise in power quality (PQ) concerns faced by the utility. A novel control strategy implementing reference compensation current was proposed in this paper. So that these grid-connected inverters can a...
متن کاملanti-islanding protection of grid connected distributed generators
a critical protection requirement for grid connected distributed generators (dg) is anti-islanding protection. in this paper, a new islanding detection method for any possible network loading is proposed based on utilizing and combining various system parameter indices. in order to secure the detection of islanding, eight intentional disturbances are imposed to the system under study in which t...
متن کاملComparative Power Quality Analysis of Different DSTATCOM Topologies
This paper presents the three topologies of three-phase four-wire DSTATCOM for reduction of harmonics, reactive power compensation, increasing power factor, which occur due to a nonlinear load, environment problem and polluted grid. The performances of the above topologies have been compared for the magnitude of source current, power factor improvement, DC-link voltage regulation, and total har...
