1. The wind is always changing, and the power fluctuations can be extreme. We need to harvest it when it is there, and either store it for periods of calm, or use some other power source as a back-up. In the days of corn-grinding windmills, the millers kept a store of grain, and ground it as and when they could. Nowadays, small wind-electric systems use batteries, which absorb surplus power during windy weather, and keep the supply going during calm periods [1]

2. There are varieties of clean energy sources available on the world. The sustainable resources such as sun, water and wind are very important and significant renewable sources of nature. Many of scientists and technologists are trying to produce the clean and effective energy from natural sources. Among renewable energy sources for Myanmar, wind is the most widely used resource due to its commercial acceptance, low cost and ease of operation and maintenance, and least adverse effect on the environment.[2]

3. The most special feature about wind turbines is the fact that, unlike other generation systems. the power inflow rate is not controllable. In most power generation systems. The fuel flow rate, or the amount of energy,[3]

4. As the technology of wind power generation is improved; the blade of wind … The present effort of understanding the nature of wind power technological developments, existing performance is an initiative to contribute towards the national wind energy development program[4]

5. Composites have been the material of choice for wind turbine blade construction for several decades. This chapter explains why. It also shows how wind turbine blade materials and our understanding of their fatigue behaviour have developed recently, and the gaps that still exist in the knowledge.[5]

6. Furnaces are most commonly used for melting of materials. Induction furnaces are more beneficial as no fuel is required. It is a problem to find life of Induction Melting Furnace wall under thermal fatigue. The induction melting furnace wall is made of alumina ramming mass which is one kind of refractory material. The failure occurs due to cyclic thermal stresses. Temperature distribution and thermal stress distribution fields of the induction melting furnace refractory wall were calculated by using ANSYS finite element analysis software based on the physical description of its failure under thermal fatigue conditions.[6]

7. Magnet permanen bonded dibuat dengan mencampurkan bahan serbuk magnet

8. Neodymium besi Boron (NdFeB) komersil type MQP 16-7 dengan bahan polimer serbuk phenol formaldehyde (bakelite) dan serbuk resin pvc.[7]

9. Data potensi energi angin yang baik merupakan salah satu faktor yang menentukan keberhasilan suatu pengembangan energi angin.[8]

10. kumparan kawat konduktor yang berada pada medan magnet yang berubah terhadap waktu maka pada ujung-ujung kawat akan timbul tegangan atau gaya listrik (ggl)induksi.syarat utama, harus ada perubahan fluks magnetik, jika tidak maka tidak akan timbul listrik.[9]

11. Daya yang dihasilkan pada turbin angin savonius ini berdasarkan pengujian dengan sudu pengarah tidak sesuai dengan daya rencana awal yaitu 132 watt sedangkan daya yang dihasilkan adalah 35,964 watt.[10]

12. Pada dc-dc boost converter, arus masukan dan tegangan keluaran masih menghasilkan ripple yang cukup besar. Ripple merupakan masalah yang mengurangi kehandalan dari konverter itu sendiri[11]

13. Wind Energy Comes of Age is the most thorough assessment ever published of the technology, economics, and politics of generating electricity with wind. It provides an up-to-date status report on the modern wind industry worldwide[12]

14. Green Technology is an eight-volume set that examines the relationship between human activities and their sometimes harmful consequences for the environment and explores new methods of repairing and restoring the Earth.[13]

15. The paper presents an algorithm to rate off-grid systems. Fraunhofer WiBACK Wireless Backhaul Repeater represents the load of these systems.[14]

16. The present invention relates to a maritime power plant system with processes for producing, storing and consuming regenerative energies whereby the power plant system may comprise an individual power plant or may be a network of power plants, whereby the power plant has a common support structure for the devices producing energy and for the devices carrying out other processes.[15]

17. Der Autor bereitet in seiner Arbeit erstmals den Rechtsrahmen für die Errichtung von Kleinwindanlagen umfassend und praxisorientiert auf. Er analysiert dabei zahlreiche Einzelprobleme und führt diese einer rechtswissenschaftlich fundierten Lösung zu. Der erste Teil der Arbeit fokussiert das formelle Anlagenzulassungsrecht.[16]

18. biotypes is a challenge to insect resistance breeding programs. The aim of this study was to detect the existence of biotypes within two Russian wheat aphid populations sampled[17]

19. The model implemented in this work gives the best agreement between experimental and simulated Comparison between different mathematical models for the simulation of a wind turbine In fluid dynamics wind turbine design, maximization of the power coefficient C P[18]

20. brief historical part explaining the development of wind power, as well as a part dealing with economy and wind turbine design[19]

21. performance of rotors designed with a blade-element based opti- mum design procedure.The second part considered rotors with constant-chord, untwisted blades[20]
