Design and Implementation of Solar Water Pumping System using Kalman Filter MPPT Technique

Abstract

Demand of renewable energy sources is gradually increasing because of the high cost and limited conventional energy sources like oil, gas, coal. In renewable solar based power systems is gaining recognition due to the availability of high solar insolation in India. Application of solar photovoltaic technology as a stand alone system has many advantages such as no maintenance required, long lifetime, environment friendly etc. The objective of this project is to develop a high efficiency solar water based pumping system. Therefore, maximum power point tracking (MPPT) method is essential in a PV system. Because of the nonlinear behavior of PV systems maxi-mum power point varies based on the solar irradiance level and temperature. So, it is necessary to track maximum power point at different solar irradiance and temperature variation to achieve maximum efficiency. The investigation includes discussion of various MPPT algorithms and control methods. MATLAB simulations verify the system and functionality of MPPT. These MPPT algorithms are implemented in floating point DSP TMS320F28069 and results are verified. A prototype of solar water pumping system having motor rated 1hp, three phase induction motor will be employed.
