Wind turbine by engr. ALI AKHTAR
Wind turbines convert the kinetic energy of wind into mechanical energy using rotor blades, a shaft, and a generator. As wind passes through rotor blades, aerodynamic forces cause them to spin and transfer the wind's kinetic energy into rotational mechanical energy. This energy spins the attached shaft, which then spins the generator to produce electricity through electromagnetic induction. In this way, wind turbines are able to harness wind energy and generate electricity in a three-step process of capturing wind energy, converting it to mechanical energy, and then converting that to electrical energy.

Session 15 wind power
Wind energy is a variable resource that is difficult to integrate into electric grids due to its high variability and lack of correlation with demand. A study in Minnesota found that increasing wind penetration from 15-25% would increase costs to load by $2.11-$4.41/MWh due to balancing needs. The study also found that combining balancing areas and utilizing a wider geographic footprint reduced costs by making the wind output more stable. Significant transmission upgrades would be required to access the best wind resources.
Generation of electricity
Electricity is generated through various processes that convert other forms of energy into electrical energy. Historically, ancient Greeks discovered static electricity and Ben Franklin experimented with electricity using a kite. Modern generation uses processes like Faraday's law of induction. Common methods include burning fossil fuels in power plants to heat water and power steam turbines, using nuclear fission in nuclear plants, and harnessing the kinetic energy of moving water in hydroelectric dams. Renewable sources also generate electricity through technologies that convert wind, solar, tidal, and geothermal energy. Electricity is transmitted through power lines using alternating current of a standard frequency.
Intro to wind energy
This document discusses factors to consider when installing a wind power plant. It compares wind power to nuclear and solar power, noting wind power plants are less complex and costly than nuclear but require more land and maintenance than solar. Key factors for installing wind power include wind resources, environmental impacts, economics, and grid connection requirements. The document also provides an example analysis for installing a 100MW wind farm in Visakhapatnam, India to help meet the region's energy needs.
Wind power plant
Wind power plants harness the power of wind to generate electricity. They work by using wind turbine blades to capture the kinetic energy of the wind and convert it into rotational energy to spin a shaft. This shaft spins a generator to produce electricity. India has over 19,000 MW of installed wind power capacity as of 2013, the fifth largest in the world. The state of Tamil Nadu generates the most wind power in India. Wind power is a renewable and clean energy source but suffers from intermittent availability due to fluctuating wind speeds.
Wind energy and its application
The document discusses wind energy and its applications. It explains that winds are caused by solar heating of the Earth's surface and its rotation. It notes that the potential wind energy available is large, at 1.6x107 KW, and is a free and clean source. However, utilizing wind energy can be challenging because the energy is available in a dilute form, requiring large conversion machines, and availability varies with location and over time. Windmills convert the kinetic energy of wind into mechanical or electrical energy. The document describes different types of horizontal and vertical axis windmills, including their components and design considerations. It concludes by noting both the advantages of wind energy being free and renewable, and the disadvantages of its intermittent nature
Wind Power Plant
This document summarizes information about wind power. It discusses how wind is formed due to uneven heating of the Earth's surface creating low and high pressure regions. Wind power depends on wind speed, turbine availability, and turbine arrangement. There are two main types of wind power plants: on-shore and off-shore. On-shore plants have lower costs but off-shore plants access stronger winds. Wind turbines work by converting the kinetic energy of wind into rotational motion that spins a generator to produce electricity. The document also describes the different types of wind turbines, including horizontal axis wind turbines and vertical axis wind turbines, noting their various advantages and disadvantages.
Wind turbine slide show 1
Wind farms consist of wind turbines that convert the kinetic energy of wind into electrical energy. Wind turbines work best in open, windy areas and use blades attached to a generator to harness the wind's movement and produce electricity. The generator is powered by the spinning blades, and the electricity is transmitted through a system that controls the constant movement of the blades.
Wind Energy Systems & It`s working
Wind power harnesses the kinetic energy of wind to generate electricity through wind turbines. It works by converting the kinetic energy of wind into mechanical energy with the turbine's blades, which then drives a generator to produce electricity. The sun provides the original source of energy for wind by differentially heating the earth's atmosphere and surface, which causes air currents and wind patterns. The United States generates over 7% of its electricity from wind power as of 2020, with Texas, Iowa, Oklahoma, and California leading in installed wind capacity.
Wind turbines basics & betz law
Betz's law indicates the maximum power that can be extracted from the wind, independent of the design of a wind turbine in open flow. It was published in 1919, by the German physicist Albert Betz.[1] The law is derived from the principles of conservation of mass and momentum of the air stream flowing through an idealized "actuator disk" that extracts energy from the wind stream. According to Betz's law, no turbine can capture more than 16/27 (59.3%) of the kinetic energy in wind. The factor 16/27 (0.593) is known as Betz's coefficient. Practical utility-scale wind turbines achieve at peak 75% to 80% of the Betz limit.[2][3]
The Betz limit is based on an open disk actuator. If a diffuser is used to collect additional wind flow and direct it through the turbine, more energy can be extracted, but the limit still applies to the cross-section of the entire structure.A wind turbine is a device that converts kinetic energy from the wind into electrical power. The term appears to have migrated from parallel hydroelectric technology (rotary propeller). The technical description for this type of machine is an aerofoil-powered generator.
The result of over a millennium of windmill development and modern engineering, today's wind turbines are manufactured in a wide range of vertical and horizontal axis types. The smallest turbines are used for applications such as battery charging for auxiliary power for boats or caravans or to power traffic warning signs. Slightly larger turbines can be used for making contributions to a domestic power supply while selling unused power back to the utility supplier via the electrical grid. Arrays of large turbines, known as wind farms, are becoming an increasingly important source of renewable energy and are used by many countries as part of a strategy to reduce their reliance on fossil fuels.
WIND ENERGY (A SOURCE OF RENEWABLE ENERGY)
Wind energy provides a clean, renewable source of electricity. Wind is caused by differences in the heating of the Earth's surface by the sun, which causes air to move from higher to lower pressure areas. The growth of wind energy has been driven by declining costs as turbine technology has advanced, with larger and more efficient turbines able to generate electricity for less than 5 cents per kWh. While wind farms can power many homes, their development requires consideration of potential impacts on property values, wildlife, and noise levels through proper siting.

CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECT
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.
Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Comparative analysis between traditional aquaponics and reconstructed aquapon...
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
