A SOLAR PV MULTILEVEL INVERTER FOR ENHANCEMENT OF POWER QUALITY IN TRAM WAYS

electrical engineering

This paper presents a transformer less hybrid series active filter is proposed to enhance the power quality in single-phase systems with critical loads. The energy management and power quality issues related to electric transportation and focuses on improving electric vehicle load connection to the grid. The control strategy is designed to prevent current harmonic distortions of nonlinear loads to flow into the utility and corrects the power factor of this later. While protecting sensitive loads from voltage disturbances, sags, and swells initiated by the power sys- tem, ridded of the series transformer, the Configuration is advantageous for an industrial implementation. This polyvalent hybrid topology allowing the harmonic isolation and compensation of voltage distortions could absorb or inject the auxiliary power to the grid. Aside from practical analysis, this paper also investigates on the influence of gains and delays in the real-time controller stability. The simulations results presented in this paper demonstrating the effectiveness of the proposed topology using MATLAB software.
