Introduction

The limited global reserves of fuel and energy, the uneven distribution of them throughout the world, the worsening of the ecological situation are raising the question of the worldwide use of unconventional clean energy technologies and the use of renewable energy resources. The active use of environmentally friendly energy sources is now a kind of a sign of good tone, in every way is welcomed by both the world community and the governments of developed countries. Of such energy, the most common and affordable is wind. Wind turbines do not require fuel or water, they can be fully automated, the territory to be alienated is minimal and is estimated to be 3-5 m2/kW of installed capacity. These installations are almost fully factory ready, and their installation requires a minimum of time – the foundation and the connection to the network.

1. Theme urgency

Wind power in recent years has become one of the most sought-after sources of alternative energy. People have long thought about how to use the powerful force of air masses. At the moment, the potential of wind energy is enormous and is developing quite quickly. The climatic conditions of almost any region make it possible to actively develop wind energy in vast territories in hundreds of different countries. Wind energy does not depend on the season and the place where it is planned to accumulate. In winter or summer, in the snowy north or in the hot south – the wind is everywhere, which makes this method of obtaining energy quite promising. Wind power is the most profitable (and therefore more common) in regions with an average annual wind speed of at least 6 meters per second. And also in regions where there are very few other energy sources, and the delivery is quite problematic and has a high cost. For such regions, the use of wind power is a way out of a difficult situation and independence from any conditions dictated from outside. Wind energy is very popular and is used in all branches of human life: in private houses, on farms and large industrial productions, you can see different wind installations. Wind energy is an environmentally friendly way of obtaining energy, which is paid a lot of attention in modern society. Its potential is great and it is very likely that, thanks to the efforts of specialists, in 10-20 years it will become an integral part of our life.

2. Goal and tasks of the research

The main goal of the work is to create a model for studying the various modes of operation of a wind generator installation.

Main tasks of the research:

  1. Research of existing types of wind turbines;
  2. Selection of the main components of the wind wind turbines;
  3. Selection of the method for implementing the task in the Matlab software package;
  4. Calculation of wind turbine parameters.

Research object: wind turbine.

Research subject: simulation of wind energy unit operating mode.

As part of the master's work, it is planned to obtain relevant scientific results in the following areas:

  1. Development of a model for research the operating modes of a wind turbine;
  2. Modification of the known models of the wind turbines installation and evaluation of their effectiveness.

Conclusion

In the course of the scientific research work of students was studying the works of the wind generator installation. In particular, the main components were studied, the quality of the efficiency of the wind-generator installations was assessed. The principle of operation, types and application of the wind generator installation were considered. Studied various models of operating modes of wind turbines.

This master's work is not completed yet. Final completion: June 2019. The full text of the work and materials on the topic can be obtained from the author or his head after this date.
