A SMALL WIND ENERGY SYSTEM TO SAVE HOME ELECTRICITY



ABSTRACT
Wind is the motion of air about the earth caused by its rotation and by the
uneven heating of planet surface by the sun. The basic concept of the wind energy
generation by using the wind flows to rotate a turbine generator. Even though, wind
power is not popular in Malaysia but it is widely used in United Kingdom, United
State and France. Nowadays, our electricity bill always increases every year cause of
increasi ....etc

ENHANCED PERFORMANCE OF A DOUBLY FED
WIND-POWER INDUCTION GENERATOR AT WIND-
RANGE BOUNDARIES
ABSTRACT
The doubly fed induction generator (DFIG) is one of the largest generators used
with MW-class wind turbines. This paper focuses on the weak performance areas
of grid-connected DFIG-based wind turbines. Basically, the DFIG performance at
low wind speeds, close to the cut in speed, and around the full rating operation (in
the vicinity of rated wind speed) is investigated. For low wind speed region, the
causes of decreased efficiency ....etc

Introduction

Power supply from PHCN or NEPA has been epileptic and always irregular with outages which last up to 8 hours in a single day. When power is restored, sparks, fluctuation and voltage surge has been a common occurrence. Undoubtedly, this is not adequate or conducive for our equipment and other sensitive gadgets. This equipment can easily be damaged by voltage fluctuation, sudden power cut due to lack of constant power source.
Electrical generator which serves as an option for many people cost a l ....etc

Formally known as a salinity gradient solar pond, solar ponds are an alternative source of harnessing the suns energy to heat water that can be converted to electricity. This technology is very basic and easy to use with adequate land space and proper design. For residential use, ponds need to be at least 12x12 feet and 3 feet deep and for commercial use ponds must be sized according to their functionality. Solar ponds require lots of sunlight and salt water. The first solar pond was discovered in the early 1900s in Tr ....etc

INTEGRATED SOLAR-WIND SYSTEM FOR GENERATION OF ELECTRICITY



I. INTRODUCTION

Geothermal power plants are an established technology to provide base load electrical power generation. In a northern climate, there are two annual peak electrical usage periods, in the summer due to air conditioning and in the winter due to structure heating and low daylight hours. Direct solar systems match the summer electrical load, but they provide almost no output during the cold and dark winter ....etc

Abstract :
A stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gases (working fluid) at different temperature levels such that there is a net conversion of heat. The general cycle of a stirling engine consists of compressing cool gas, heating the gas, expanding the hot gas, and finally cooling the gas before repeating the cycle. The working fluid inside the stirling engine in this case is heated gas using solar energy from the sun.
The main components of this project are:
Stirling En ....etc

Introduction

Windpower technology dates back many centuries. There are historical claims that wind machines which harness the power of the wind date back beyond the time of the ancient Egyptians. Hero of Alexandria used a simple windmill to power an organ whilst the Babylonian emperor, Hammurabi, used windmills for an ambitious irrigation project as early as the 17th century BC. The Persians built windmills in the 7th century AD for milling and irrigation and rustic mills similar to these early vertical axis designs can ....etc
