Dynamic Performance of PV Array fed Vector Drive Unit

Abstract

In emerging applications of solar powered units the significance of its operation and control plays vital role. Industries to home, in all applications need induction motors due to its robust, simple and reliable.so this type of machines used widely in variable speed applications. In the scenario this paper presents the operation and dynamic performance of vector drive fed by PV array. Any drive unit equipped with power management unit, signal conditioning, drivers and controllers and control unit. This system powered by the excitation from PV array with MPPT controller and the load here is a vector drive. Vector control is advantageous over scalar control due to its low speed regulation, low maintenance and minimum speed at Rated torque and wide base speed range. The proposed system consists of PV array, MPPT Controller, vector controlled drive. Solar panel output boosted using Dc-Dc converter with Maximum power point tracking controller Using Incremental Conductance method and the performance curves(P-V, I-V,V-I) presented. Dynamic modelling and analysis of Individual units and the respective performance curves presented here and the simulations done in MATLAB/SIMULINK Platform.
