Design of Solar-PV Powered BLDC Motor Drive for Water Pumping System with Grid Integrated Features

Electrical & Electronics Engineering

The full utilization of a PV array and motor-pump is made possible in addition to an enhanced reliability of the pumping system. A single phase voltage source converter (VSC) with a unit vector template (UVT) generation technique accomplishes a bidirectional power flow control between the grid and the DC bus of voltage source inverter (VSI), which feeds a BLDC motor. Additionally, regulation of DC capacitor voltage in UVT controller at a desired level using a PI controller is not suitable for enhanced PQ features. But, this controller is unpopular due to tuning issues of current controller; the above-mentioned issues are regulated by using novel intelligent based Fuzzy-Logic controller achieving good performance features. The proposed intelligent Fuzzy control schemes are highly used in several applications, has been greatly recognized due to enhanced performance over the classical PI controller. This work compares the performance of solar-PV and grid integrated water pumping system with classical PI and intelligent Fuzzy-Logic controller in PQ enhancement. The maximum power point (MPP) operation of a PV array and power quality improvements such as power factor correction and reduction of total harmonic distortion (THD) of grid are achieved in this system by using Matlab/Simulink platform, results are presented.
