Remote Power Stand Alone System Using Solar-Wind-Biomass Energy

ABSTRACT- Due to the limited reserves of fossil fuels and global environmental concerns for the production of electrical power generation and utilization, it is very necessary to use renewable energy sources. By use of hybrid systems we can implement renewable energy sources which are very economical for remote villages, homes etc. In particular, rapid advances in wind-turbine generator, biomass generator and photovoltaic technologies have brought opportunities for the utilization of wind and solar resources for electric power generation world-wide .So by the use of hybrid systems consisting of Biomass, PV and also wind for production of electrical energy in these remote areas can be more economical. If the development of a computer-based approach for evaluating, the general performance of standalone hybrid PV- Biomass-wind generating systems are analyzed ,then these results are useful for developing and installing hybrid systems in remote areas This paper focuses the economical consideration and simulation approach for a standalone hybrid systems having PV, wind and Biomass for electrical production in remote areas. In this paper we are taken the average solar radiation, quantity of biomass, average wind speed for the remote area for prediction of general performance of the generating system.

Full Wave Bridge Rectifier With Capacitor Filter

Full Wave Bridge Rectifier With Capacitor Filter The voltage obtained across the load resistor of the full-wave bridge rectifier described above has a large amount of ripple. A capacitor filter may be added to smooth-en the ripple in the output, as shown below. Figure 21: Full wave Bridge rectifier with capacitor filter The rectifier circuits discussed above can be used to charge batteries and to convert AC voltages into constant DC voltages. Full-wave and bridge rectifier are more commonly used than half-wave rectifier.

BLDC Motor Driven Solar PV Array with Battery Fed Automatic Irrigation System Employing Zeta Converter

Objective The main objective behind this project is to design a simple, cost effective and efficient brushless DC (BLDC) motor drive for solar photovoltaic (SPV) array fed water pumping system. The project includes automatic changeover circuit to switch power source between solar panel and battery based on the presence and absence of light. The pump works on the signals received by the sensors used for automatic irrigation system. Abstract This project proposes a simple, cost effective and efficient brushless DC (BLDC) motor drive for solar photovoltaic (SPV) array fed water pumping system. A zeta converter is utilized in order to extract the maximum available power from the SPV array. The proposed control algorithm eliminates phase current sensors and adapts a fundamental frequency switching of the voltage source inverter (VSI), thus avoiding the power losses due to high frequency switching. No additional control or circuitry is used for speed control of the BLDC motor. The

SMART HOME AUTOMATION USING DTMF

1. INTRODUCTION We use many different types of communication in control applications to control home appliances, industrial appliances, and other type of automation. There are two types of communication that is we generally use - one is wired and other one is wireless. In wireless communication we transmit signal wirelessly, like using radio frequency (RF) and in wired communication in which we use wires like copper wire. In this project “DTMF Based Home Automation System” we are going to control our home appliances wirelessly. Other important feature of this project is, that we are not going to use any microcontroller in it. . The remote control used in home automation systems, is a wonderful feature that everyone would like to enjoy, if they were not expensive to install, maintain, and able to be use from long distance. With such automation one can switch ON and OFF lights, Ac etc. from a remote distance. In our project we have tried to implement this home automation technique u
