Wind Electrical System

Description

A wind electric system is made up of a wind turbine mounted on a tower so as to provide better access to stronger winds. A turbine and a tower aside, small wind electric systems also require balance-of-system components. The wind resource determines energy production, and the swept area of a wind turbine is second-most in the line of significance. The circle swept by the blades of the windmill is the collector area. It’s not possible to get a large amount of energy out of a small collector area. Betz’ theorem says we can only get about 60% of the energy out of the wind, before its performance starts decreasing.
Both upwind is when the wind hits the turbine before it hits the tower, and downwind is when the wind hits the tower before it hits the turbine, can be exceedingly effective. Wind turbines should be sited at least 30 feet or 9 metres higher than anything within 500 feet or 152 metres. Three common types of towers are tilt-up, fixed-guyed, and freestanding. Towers must be specifically engineered for the lateral thrust and weight of the turbine, and should be adequately grounded to protect your equipment against lightning damage.
This book assumes no prior knowledge in the field and therefore would be very relevant for readers with a non-electrical-engineering background. The author of this book is a well-regarded expert in this subject.
