Simplified Method for Substation Grounding System Design

This paper focused 230 66 kV, substation grounding system and calculation results of required parameters at location of Kalay region. The grounding system is essential to protect people working or walking in the vicinity of earthed facilities and equipments against the danger of electric shock. It provides the floor surface either assures an effective insulation from earth potential or effectively equipment to a close mesh grid. Calculations of grounding grid system in the substation area where the top soil layer resistivity is less than the bottom layer resistivity can be less the number of ground rod used in the grid because the value of Ground Potential Rise GPR is insignificantly different. To get desired parameters such as touch and step voltage criteria for safety, earth resistance, grid resistance, maximum grid current, minimum conductor size and electrode size, maximum fault current level and resistivity of soil are designed in detail consideration.

3kw Propeller Turbine Blade Design Based on Tidal Range

Tidal energy is a largely untapped, renewable energy source based on lunar gravitation rather than solar radiation. The generation of electricity from tides is very similar to hydroelectric generation. Tidal energy is clean and not depleting. The tidal schemes may be of single pool or double pool or multi pool. Two types of tidal power plant are barrage style tidal power plant and tidal current power plant. Among them, barrage style tidal power plant was chosen to suit local condition and facilities in Myanmar. Several different turbine configuration are possible. The propeller turbine designed is based on tidal head and flow rate of Kanbalar Creek. The maximum and minimum head of tidal range is 5 m and 2 m. The available flow rate is 0.46 m3 s. The type of turbine is chosen by using 2 m head and 0.46 m3 s flow rate. Therefore, 3 kW propeller turbine is designed in this paper. Then, calculated runner diameter is 280 mm, hub diameter is 112 mm and number of blade is four. Two dimensional blade profile is calculated by using MATLAB program software and drawn Auto CAD software.

Design and Construction of Pedal Operated Water Pump

This paper describes the design and construction of the pedal operated water pump are done especially discharge rate at different speed and height. The proposed pump is a rotary pump operated by pedal power. In the rotary pump, water enters axially through the vane eyes and exits radially. In this paper, necessary dimensions are calculated for the design point of 6.096 m 20 feet height, 0.00018 m3 sec flow rate and rotational speed 260 rpm. Pedal operated water pump is purposed to use in small irrigation and garden irrigation and drinking water where electricity is not available.

An Experimental Study on Stabilization of Clayey Soil by Using Granulated Blast Furnace Slag

Many of the areas in India contains clayey soil, for these soils Geotechnical properties are a week, which affects the stability of the soil. As Ground granulated blast furnace slag contains in this study, we received the Ground granulated blast furnace slag from steel plant waste mixing with clayey soil to enhance geotechnical properties and make it more suitable for use. In this effect of stabilized soil and change in geotechnical properties. Treatment of clayey soil using with GGBS is very simple, economical and pollution control. Ground granulated blast furnace slag GGBS and this material are obtained from the blast furnace of cement plant, which is the by product of iron from ACC plant, Sindri . It is generally obtained in three shaped one is air cooled, foamed shaped and another is in granulated shaped. The use of by product materials for stabilization has environmental and economic benefits. Ground granulated blast furnace slag GGBS material is used in the current work to stabilize soil clay . Ground granulated blast furnace slag which can be used as a stabilizer. GGBS were mixed in clayey soil in different proportions and various geotechnical characteristics are investigated through Unconfined Compression Test, Compaction Test, CBR test results show that addition of Ground Granulated blast furnace slag has a significant effect in geotechnical Characteristics of clayey soil.

Soil Stabilization by Using Lime and Fly Ash

For any type of structure, the foundation is very important and it has to be strong to support the entire structure. In order for the strong foundation, the soil around it plays a very critical role. To work on soils, we need to have proper knowledge about their properties and factors which affect their behaviour. By consolidating under load and changing volumetrically along with seasonal moisture variation, these problems are manifested through swelling, shrinkage and unequal settlement. In this paper the experimental results obtained in the laboratory on expansive soils treated with industrial waste fly ash and lime are presented. A study is carried out to check the improvements in the properties of expansive soil with fly ash and lime in varying percentages. The test results such as liquid limit, standard proctor and differential free swelling test obtained on expansive clays mixed at different proportions of lime and fly ash admixture are presented and discussed in this paper. The results show that the stabilized clay has lesser swelling potential whereas an increase in optimum moisture content has been observed.

Carrot dessert with rice balls were prepared from different proportion of carrot puree, rice flour, sugar, milk and water i.e. T1 formulation was 27 16 16 21 20 carrot puree milk rice flour sugar water for T2 formulation was 22 21 21 16 20 carrot puree milk rice flour sugar water whereas T3 21 27 11 21 20 carrot puree milk rice flour sugar water. For this carrot dessert rice balls physicochemical and sensory analysis was carried out. The results showed that sensory evaluation and overall acceptability of carrot dessert with rice balls of treatments T1, T2 and T3 were noted as 8.3,7.9 and 7.4 respectively. It was observed that the carrot dessert with rice balls T1 was most acceptable and ranked between like very much. T1 showed moisture 61.57, fat 2.5 , protein 4.2, Carbohydrate 28 , total sugar 24.0 ash 3.8, energy by formula calculated 151.3Kcal respectively. Hence T1 have rich nutritive value and literature also showed for carrot with nutrient such as Beta carotene precursor of vit. A, Minerals, Amino acid, Calories, Antioxidants etc. Hence this recipe of carrot dessert suitable for supplementation of Vit A deficient, heart patient and cancer patients which are having good therapeutic value.

Active and Reactive Power Control of DFIG Based Grid Connected Wind Energy System

Wind power is the most reliable and developed renewable energy source. This paper gives a study on power flow control of a grid connected Doubly Fed Induction Generator DFIG wind turbine. Doubly Fed Induction Generator DFIG has widely used for large wind farms. A back to back converter is incorporated between the stator and the rotor windings of a DFIG, in order to obtain variable speed operation. The controller design methodology is presented and active and reactive power is verified. The main objective of the paper is to control the flow of the active and reactive powers produced by the DFIG based wind energy conversion system. In order to decouple of active and reactive powers generated, the vector control method is applied. A vector control strategy with stator flux orientation is applied to both the grid side converter and the rotor side converter for the independent control of active and reactive powers produced by the DFIG based wind energy conversion system. Simulation results on a 2MW DFIG system are provided to demonstrate the proposed control strategy and the variations of active and reactive power, rotor speed, and converter dc link voltage.
