PROJECT TITLE :

Power quality enhancement for a grid connected Wind turbine energy system - 2017

ABSTRACT:

A comprehensive management of a wind turbine system connected to an industrial plant is discussed during this paper, where an algorithm has been developed permitting a management structure that utilizes a four-leg inverter connected to the grid side to inject the obtainable energy, also to work as an active power filter mitigating load current disturbances and enhancing power quality. A four-wire system is considered with three-section and single-section linear and nonlinear hundreds. Throughout the affiliation of the wind turbine, the utility-facet controller is intended to compensate the disturbances caused in presence of reactive, nonlinear, and/or unbalanced single- and intra-section loads, additionally to providing active and reactive power as required. When there's no wind power on the market, the controller is meant to improve the power quality using the dc-link capacitor with the facility converter attached to the grid. The main distinction of the proposed methodology with respect to others in the literature is that the proposed management structure is based on the conservative power theory decompositions. This choice provides decoupled power and current references for the inverter management, providing very versatile, selective, and powerful functionalities. Real-time software benchmarking has been conducted so as to evaluate the performance of the proposed management algorithm for full real-time implementation. The management methodology is implemented and validated in hardware-in-the-loop primarily based on the $64000 time simulator “Opal-RT” and a TMSF28335 DSP microcontroller. The results corroborated our power quality enhancement control and allowed to exclude passive filters, contributing to a more compact, versatile, and reliable electronic implementation of a smart-grid based control.
