This chapter describes the features of the work of wind-receiving devices in the insufficient power mode when the current wind speed is below the construction value of the wind power plant. The term “effective angle” is introduced. The importance of this problem is shown and the amount of time in the insufficient power mode, for example, wind power plant, is calculated. The main characteristics of an electrical generator and a wind receiving device are considered. The importance of the mapping the characteristics of the wind-receiving device and the electrical generator is shown.

Wind Flow

The questions connected with increase of efficiency of functioning of a wind power plant with a vertical axis of rotation are considered.Such plants convert the energy of the wind flow into rotational energy of the generator shaft, pump or other actuators. An overview of the design options for wind turbines of this type is presented. For vertically-axial wind power plants, in comparison with horizontally-propeller ones, it is possible to increase their efficiency by providing insensitivity to wind direction change. This is possible provided that the angular position of the blades with respect to the wind flow is continuously and purposefully changed as the wind turbine rotates. The principle of increasing the efficiency of the wind power plant is proposed due to the synchronous control of the position of the blades, depending on the direction and speed of the wind flow. The implementation of this principle is considered in detail for a four-bladed wind turbine. Depending on the direction and magnitude of the wind flow, as well as the angular velocity of rotation of the turbine, the value of the angle of the initial installation of the blades was analytically obtained, which ensures the maximum efficiency of using the wind plant. The functional scheme of the control system of the orientation of the four blades is formed. This system uses information about the current power of the generator, the rotation speed of the wind turbine, the direction and speed of the wind flow, obtained from the respective sensors. A detailed functional diagram of one channel of the control system has been constructed taking into account the initial exposure of the blade, which additionally uses information about the current angular position of the blade and the speed of its turn. Each such channel contains a proportional-differential controller or fuzzy logic controller. The proposed fuzzy controller has two inputs of linguistic variables - the angle of rotation of the blade and the speed of its rotation. As a kind of membership functions, a triangular distribution is chosen. A system of rules for adjusting the fuzzy controller has been developed. The computer simulation of the channel functioning of the control system with two types of regulators for the mode of initial setting of the blades with a change in wind direction was performed. Comparison of the quality of the control system with a proportional-differential and fuzzy controller is performed

A prototype of a wind power plant had been created using a ventilator  as a generator spiner. This power plant utilizes wind speed as its propulsion. Electricity generated in the DC voltage form between 0 volts up to 7.46 volts. The MT3608 module is used to stabilize and raise the voltage installed in the input and output of the charging circuit. For instrument testing, the wind speed on 0 m/s up to 6 m/s interval used. Maximum output of this tool with a wind speed of 6 m/s is 7.46 volts.
