Wing Tip

Indonesia currently has a growing need for energy, this will experience an energy crisis, dependence on fossil fuels will at least have a serious threat, therefore there must be alternative energy as a substitute and reserve such as wind energy, water energy, solar energy, and other. This study aims to develop a wind power plant as an alternative source to produce electrical energy, namely a wind turbine. This tool is used to meet energy needs and also as an alternative energy so that fossil fuels will not run out. Because Indonesia is an archipelagic country and is located on the equator, Indonesia is a country that has abundant resources, one of which is wind. Wind turbine is a tool that functions to convert wind power into mechanical power in the form of a shaft rotation, this shaft rotation is then used for power generation or for water pumps. Therefore I tried to develop my ideas to utilize abundant natural resources to be used as a source of electrical energy by means of a wind turbine using a Naca 0018 blade. This study aims to determine the effect of the number of blades, the effect of profiles, the effect of the wing tip of the rotor blades. , naca 0018, and the resulting energy efficiency. This study uses the type of experimental research.

Much human energy needs are obtained from fossil fuels. This fossil energy is decreasing day by day. So that the utilization of natural energy such as solar energy, water energy and wind energy is being developed. Wind energy is energy that we can find, so it is very easy to use by using a turbine as the driving force. The vertical axis wind turbine is a type of wind turbine that is easier to apply in places where wind potential is not too large. This research was conducted by means of simulation using Qblade v0.963 software by comparing the influence generated from several numbers of wind turbine rotor blades. From the simulation process, it is known that the wind turbine rotor blades with 4 blades are the wind turbines capable of producing the greatest power, which is 75 Watts at a low TSR. So that in the manufacturing process it does not require large costs, but it still has to be built rigid and solidly.

Abstract Eastern side of Indonesia has a group of scattered Islands and have a great distance from the main Island. Fossil fuels are the main option for meeting the needs of electrical energy in the outer Islands. But the availability of fossil fuels is very dependent on the weather and modes of transportation. In addition, fossil energy also causes emissions and environmental pollution, so efforts to diversify alternative energy by utilizing renewable energy are needed to meet energy needs. Ut Island, Maluku is one of the Islands which is not yet powered by utilities. In this paper, the HOMER software is used to determine the optimal hybrid power plant configuration from a techno-economic perspective by utilizing energy resources available on the Island. From the simulations that have been carried out wind speed has a significant influence on the optimal configuration of the PLH system. Load value affects the amount of NPC and COE. The greater the load is fulfilled, the higher the NPC. But contrary to NPC, COE value will decrease.

Energy Needs

On the increase of energy needs and rising environmental concern forces the use of renewable and to search the alternative source of energy for the polluting fossil fuels. The best alternative energy is solar which is being emitted by the sun and is collected and is stored in various thermal storage medium. Solar pond is one of the best ways to collect solar energy in that shallow solar pond is one of its type. From the name it implies the pond depth is small so the solar pond can be fabricated in a simple manner with very low cost covering large area. Previous research they have used baffle plates to find out the thermal performance, but this research brings out using CuO nano particles and has been examined experimentally. The shallow solar pond is built with a surface area of 1.7m2 with a depth of 0.5m. The experiment has been carried out during the month of April of 2016 under the climatic conditions of pachapalayam [Latitude 10.950N, Longitude 76.890E]. It was examined for the six successive sunny days and its temperature of lower convective zone varies from 1.3°C to 9.2°C, with the maximum rise in temperature is obtained when adding 0.8% concentration of nano particles.

Wind power is an important direction of new energy, which has no pollution, no consuming fossil fuels, and no producing waste, which is widely used at this stage of clean energy. The small stand alone wind power has been paid more and more attention due to its low cost, flexible installation, strong adaptability. This paper introduces the mechanical and electrical structure, which are used in KW level stand alone mode wind turbine automatically track and yaw system. The motion rules and control strategies of the tracking and yaw system are discussed and then the control program flow is provided. The PIC16F873 chip is used as controller for this part in this system. It can fully meet the design requirements, which will reduce costs and increase the system's control ability.

Savonius Wind Turbine

Nonrenewable fossil fuels are finite resources that will ultimately deplete in near future. Nature sheds colossal amount of renewable wind energy but humans harvest a morsel. Taking this into account a numerical study is proposed on wind energy harvesting from a speeding subway train. Subways trains generate a remarkable gust of wind that can be transferred to useful electrical energy on daily basis. To this aim, a numerical analysis is modeled by placing Savonius wind turbine in a subway tunnel to crop the wind energy produced from the speeding train. The passage of train in the tunnel generates very high velocity slipstreams along the length of the tunnel. The slipstream phenomena develop a boundary layer regime that will be absorbed by the Savonius wind turbine to self-start and generate power. In the present study, a two-dimensional numerical simulation with modified turbine blade design is carried out using open source tool OpenFOAM® with PimpleDyMFoam solver coupled with six degrees of freedom mesh motion solver sixDoFRigidBodyMotion and k–ɛ turbulence modeling, to measure the amount of torque predicted by the rotor from the gust of wind produced by the speeding train in the tunnel. Being a self-start turbine with no yaw mechanism required the turbine collects air from any direction and converts it into useful power.

This research discusses the fulfillment of the electricity needs of remote communities that are closely related to electrification ratios. Electrification ratios in some isolated areas and scattered islands in Indonesia are still very low. To date, most of the electricity needs in Indonesia is still supplied by Diesel Power Electricity Generator (PLTD) which uses diesel as its fuel. Therefore, it is necessary the utilization of renewable energy as one step to fulfill the electrical energy needs. This research studies about the utilization of wind energy with PLTB by using low speed wind turbine to fulfill the electricity needs of remote communities and scattered islands in Indonesia. NT1000W is the latest technology of low speed wind turbine that can operate at wind speed of 1 m/d up to 60 m/d appropriate to the wind conditions in Indonesia. Testing conducted in west Sumatera particularly in Padang city and Kapo-Kapo Island provide a feasibility of PLTB NT1000W technically and financially.
