Abstract

Earlier the PV system used to offer about 10 % efficiency only due to solar intermittency, generation losses etc. But with the increasing demand of enhancing the efficiency of a PV system, its power quality is also decreasing. For the purpose of better penetration and efficiency MPPT controllers, 6 pulse inverters etc. are being implemented which leads to the presence of harmonics at output. In this paper we have considered a grid connected PV system having MPPT controller, Inverter. Analysis is made to find the optimum maximized real and reactive power by varying no. of cells in series and parallel respectively.

Abstract

Operational control system reliability and efficiency is the important factors of the smart grid system. In this paper implementation of generalized photovoltaic and wind turbine hybrid system is developed. It consists of PV cell, wind turbine, induction generator, controller and converter this system is implemented by MATLAB SIMULINK software. The MPPT technology used here, this model  is observed under different conditions as taking solar  irradiance and temperature, this enables the PV/WIND system to be easily simulated and analyzed.

Keywords

PV Cell, Wind Turbine, MPPT, Irradiance, PI Controller.

Abstract

Objective of this project work is designed to operate as an Automated Irrigation Control and Security System with Wireless Messaging option. The main objectives of our work are to optimize proper use of water, to reduce the cost of labor and to provide high security. This project monitors the required water level in the field and throws up excess water due to heavy rain fall by controlling two electrical dewatering pumps. A wireless communication system is designed to provide field related information to the owner of the land. To ensure the security of the dewatering pumps and other electrical equipment’s, there is a password protected locking system allowing the control to the authorized person only.
