    This article discusses the concepts of harnessing electrical energy from wind power with piezoelectric crystals. In recent years, the invention and development of power electronic devices has grown rapidly and steadily, and these devices have been used in people's daily lives to make their work easier and more comfortable. The feasibility of a piezoelectric power generation system for the electric power system, with the conventional wind turbine, is discussed in this paper. Say no to plagiarism.

The wind turbine of our design consists of two main components: 1. The blades connected to the axis of the tower through which the normal operation of the wind turbine can be obtained and 2. The piezoelectric component (flag or leaf) attached to the top of the tower. from which additional energy can be obtained. When the wind blows, the pressure of the wind contributes to producing electrical energy, which is also the principle of the piezoelectric component. As the output output here is variable frequency and low voltage type, we need constant frequency and high voltage output to operate the load. Therefore, a suitable converter is used to obtain the constant frequency AC output which is then transmitted to a suitable load for testing. In today's world, energy is the most important thing, especially electricity. Renewable energy sources should be the appropriate solution to solve the problem of energy crisis. As natural resources and fossil fuels are on the verge of disappearing, researchers are working to find an alternative source of energy from nature. Due to the depletion of fossil fuels and drastic changes in climatic conditions, the use of natural renewable energy for electricity generation has become essential. Fossil fuels are being exhausted for electrical power generation and scientists predict that fossil fuels will be exhausted in the near future. Alternatives must not be harmful to the environment. Human beings on this planet have started using energy harvesting technology in the form of wind, geothermal and solar energy. Today, renewable energy resources are more focused and researchers are currently interested in the use of piezoelectric crystals. After solar energy, wind energy is the most efficient energy because wind is a clean and renewable energy source that has been used to produce electrical energy and in addition, piezoelectric transducers are used to convert vibrational energy into electrical energy. Piezoelectric crystals are generally inexpensive and easy to maintain and are available in abundance. The piezoelectric crystals used are ceramic quartz crystals and are one of the small-scale energy sources. Whenever piezoelectric crystals are subjected to mechanical vibration, they generate a small voltage. Wind turbines could also be used in shaded environments. The proposed system consists of a conventional wind turbine with piezoelectric component boost circuits and filter circuits. The topology of piezoelectric wind turbines uses twoenergy production systems, according to which two principles are used. The first is a wind turbine which works on a simple principle which converts the kinetic energy of the air into mechanical energy and which in turn is converted into electricity. The second processor is described as the piezoelectric crystal which converts the mechanical energy or vibrational energy of the air into electrical energy. The piezoelectric effect converts mechanical stress into electrical current or voltage. It is based on the fundamental structure of a crystal lattice. Some crystal structures have a charge balance with negative and positive polarization, which neutralize each other along the imaginary polar axis. When this balance of charges is disrupted by an external constraint on the crystal mesh, the energy is transferred by electric charge carriers creating a current in the crystal. Conversely, with the piezoelectric effect, an external charge input will create an imbalance in the neutral charge state causing mechanical stress. The main objective of the system is to generate continuous electrical energy of considerable amount from wind energy with piezoelectric crystals. The system consists of carrying out the operation of a wind turbine which exploits wind energy with a minimum collection speed to produce electrical energy in addition to the electrical energy which is obtained using piezoelectric transducers which convert the energy vibration or air pressure into electrical energy that is used to operate the appropriate light load. EQUIPMENT REQUIRED: The following devices are required to design the piezoelectric wind turbine? Wind turbine prototype? Piezoelectric crystals? Inverters? Rectifiers? Step-up transformers? Load (e.g. bulb, fan, etc.) PIEZOELECTRIC TRANSDUCERS: The piezoelectric material described above in the block diagram is the mechanical energy or vibrational energy of the air into electrical energy, as the name suggests, piezoelectric means electricity caused by pressure. Today, the most commonly used piezoelectric transducers are lead zirconate titanate compositions and piezopolymers have also gained importance and acceptance in today's market. The advantage of piezoelectric transducers is that they are available at low cost and flexible and can be obtained in any desired shape. BOOST CONVERTER: A boost converter (boost converter) is a DC-DC power converter that increases the voltage from its input supply to its output (load). The advantage of this boost converter is that it is able to increase the voltage to the lowest possible level and the input is continuous and desirable. Boost converters or regulators are used in many cases to provide small power supplies where higher voltages may be required, too high power requirements may be required. AUTOMATIC VOLTAGE REGULATOR: A voltage regulator is designed to automatically maintain a constant voltage level. Automatic voltage regulator is used to regulate voltage. It takes fluctuating voltage and turns it into constant voltage. Voltage fluctuation mainly occurs due to load variation on the power system and automatic voltage regulators are commonly used. STEP-UP TRANSFORMERS: The step-up transformer is used in the above circuit to step up the 12V or 24V AC output of the inverter to 230V or the required level in order to operate the appropriate load. As the name suggests, STEP UP means INCREASE the voltage level. THE6.
