Abstract

The article covers issues related to non-traditional sources of electricity, namely wind energy. It is shown that every year wind energy is used on an increasingly large scale in order to satisfy the need of mankind for reliable and environmentally friendly sources of energy. It is noted that in many European countries a significant amount of energy was produced in wind energy, which is approximately 2% of its global consumption. In the developed countries of Europe, wind energy already makes up a fairly significant share of all electricity. Compared to the countries of Western Europe and the Mediterranean, Ukraine is a windless region, where winds blow more stably only in the Carpathians and on the Azov coast. Despite this, a significant number of wind power plants have already been built in Ukraine. The wind speed for the operation of industrial wind power plants must be at least 3 m/s. As a result of weak wind or its temporary absence, wind turbines operate on average at 35% of the calculated capacity. The goal of the research is to develop an ejection wind power plant that can operate at 100% of the calculated capacity due to the creation of a constant upward flow of air. The article proposes the design of an ejection vertical wind power plant, which will ensure efficient operation and will be able to operate at 100% of the calculated capacity. The methodology uses an analytical research method, which is based on the calculations of the main indicators of the ejection power plant. Also, the methodology provides means of determining the speed of the air flow, which ensures the efficient operation of power plants. In the work, the calculations of the speed of the air flow on the ejection wind intake, the dynamic pressure of the fan, the impulse of the force of the air flow on the rotor blade, the projected power, and the payback period were performed. The indicators of the linear movement of the fairing, which is in the design of the ejection power plant, depending on the drop in atmospheric pressure, are given. The developed ejection wind power plant will ensure electronic independence, environmental protection, operational safety and economy.
