Also Available Domains DC - AC Converters|AC Drives

Project Code :TEPGPS123

Objective

Main objective of this project is regulating the DC link voltage by reducing harmonics contents and DC offset in single-stage PV fed system.

Abstract

In this project, to operate water pump by using induction motor through PV-grid integrated system   is introduced. A simple approach to controlling DC link voltage is adopted for the power transfer. This scheme is used to feed the induction primarily Motor-driven water pump, and if no pumping of water is needed, the electricity is distributed to the utilities. 

This scheme includes two current Sensors and two voltage sensors for sensing and estimation purpose. Induction motor phase currents are calculated from the DC link current by updated SVM methodology. The estimate of speed in this the method is accomplished by a model based on the Artificial Neural Network (ANN) based Model Reference Adaptive System (MRAS) for Estimation of flux and is able to regulate the flow of power as per Demand. Field-Oriented Control (FOC) is used to speed control of induction motor.

A third-order integrator-based unit voltage generation algorithm is used to control the power transfer in both the direction between utility and the IMD with water pump by regulating DC link voltage. The appropriateness of the system is justified by simulated results on MATLAB/Simulink platform results procured with the help of a simulation during varying solar irradiances.
