How to choose optimal locations for installation of wind turbines in rural areas

Abstract

To choose optimal place for wind turbine, you need to know two basic parameters:1. Vavarage – the average wind throughout the year. The total amount of kilowatt hours of electricity you will get depends on this parameter. 2. Vmax – the maximum possible dangerous gust of wind during a storm. The required strength depends on this parameter and hence also the cost of construction. In order to evaluate the chosen place, it is possible to combine these two parameters to only one physical parameter Vbojat. In this article it is called: “Average wind speed which is devaluated by hurricanes” or BOJAT speed. These measurements must be done for a year or few years in advance. Two devices for such measurements are described in this article: the Anemometer and the Brazmometer. Both are purely mechanical, and that means – they are reliable and cannot loose dates because of some electrical shock. Both are made in Latvia. Also, recommendations how to make simple and cheap wooden mast for such measurements in rural area are given.
