Access to energy is a major challenge for the socio-economic well-being of populations. In Benin, the electric energy sector is characterized by a low rate of access to energy in rural area (6.6% in 2017) and dependence on the outside at 40%. In the village of Ahouandji (Ouidah commune) located on the coast of Benin and far from the conventional network, the surface winds are regular and permanent. However, this wind resource is untapped despite the unavailability of electrical energy. To cope with this difficulty, this study therefore addresses the design and sizing of a micro-wind power plant to supply the region. Wind data at 10 m above the ground recorded over the period January 1981 to December 2014 by the Agency for the Safety of Air Navigation in Africa (ASECNA) were used. Based on the socio-economic study of the locality and the statistical study of the winds by the Weibull distribution and the power law, the sizing of the wind power plant components was carried out. The economic study of the system then made it possible to assess the profitability of the project. It emerges from this study that at 25 m above the ground the Weibull shape parameter is estimated at 2.94 and the scale parameter at 6.07 m/s. The most frequent speed is estimated at 5 m/s and the one giving the maximum energy at 10.2 m/s. The micro-power plant is made up of two wind turbines with a nominal power of 29.7 kW for a daily production estimated at 355 kWh, a three-phase converter rated at 30 kW, 06 inverters/chargers with a power of 11.5 kW and 120 batteries (3000Ah/2V). The selling price of kilowatt-hour estimated at 0.17 euro/kWh is quite competitive. The establishment of this micro-wind power plant is therefore an asset for these rural populations.

ABSTRAKPertumbuhan dan konsumsi listrik yang tidak berimbang serta tingkat polusi yang terus meningkat, mendorong banyak penelitian tentang pembangkit listrik energi baru dan terbarukan. Salah satu energi terbarukan yang menghasilkan energi listrik adalah pembangkit listrik tenaga bayu. Turbin angin jenis savonius merupakan turbin yang sesuai dioperasikan dengan kecepatan angin yang relatif rendah dan cocok digunakan sebagai pembangkit listrik berskala kecil. Pada penelitian ini penulis juga mengkaji konfigurasi variasi kemiringan sudu bilah savonius tipe u overlap dan tipe u non-overlap. Agar mengetahui spesifikasi teknik pembangkit listrik tenaga bayu ini, penulis merancang prototype pembangkit listrik tenaga bayu turbin savonius dengan variasi kecepatan angin 0-8 m/s, variasi kemiringan sudu turbin sebesar 00, 150 dan 300. Berdasarkan percobaan yang telah dilakukan turbin dengan kemiringan sudu 150 pada bilah savonius non overlap menghasilkan tegangan dan RPM paling tinggi. Rata-rata tegangan yang dihasilkan pada kemiringan sudu tersebut adalah 3,61V pada 1081 RPM, dan arus keluaran mencapai 950mA dengan beban resistor 10Ω. Data logger digunakan untuk menyimpan data berbagai sensor tersebut kemudian di plot dalam bentuk grafik dengan komunikasi serial ke PC untuk selanjutnya dianalisa. ABSTRACTThe growth and disproportionate consumption of electricity as well as the level of pollution continues to increase, prompting a lot of research on new and renewable energy power generation. One of the renewable energies that produces electrical energy is wind power generation. The savonius type wind turbine is a turbine that is suitable for operation with relatively low wind speeds and is suitable for use as small-scale power plants. In this study, the author also examines the configuration of the savonius blade slope variations, type u overlap and type u non-overlap. In order to know the technical specifications of this wind power plant, the author designed a prototype of the Savonius turbine wind power plant with wind speed variations of 0-8 m/s, turbine blade slope variations of 00, 150 and 300. Based on experiments that have been carried out turbines with blade slopes 150 on non-overlap savonius blades produces the highest voltage and RPM. The average voltage produced on the slope of the blade is 3.61V at 1081 RPM, and the output current reaches 950mA with a load resistor of 10Ω. The data logger is used to store data on various sensors and then plotted in the form of a graph with serial communication to a PC for further analysis.

Resilience Index

A wind energy system transforms the kinetic energy of wind into mechanical or electrical energy that can be harnessed for practical use. Mechanical energy is most commonly used for pumping water in rural or remote locations. Electrical energy is obtained by connecting wind turbine with the electricity generator. The performance of the wind power plant depends on the wind kinetic energy. It depends on the number of design parameter of the wind turbine. For the wind power plant the wind kinetic energy conversion depends on the average wind velocity, mechanical energy conversion into electricity, and electricity transmission. Resilience of the wind power plant is the capacity of the system to withstand changes of the following parameters: wind velocity, mechanical energy conversion into electricity, electricity transmission efficiency and electricity cost. Resilience index comprise following indicators: change in wind velocity, change in mechanical energy conversion efficiency, change in conversion factor, change in transmission efficiency, and change in electricity cost. The demonstration of the resilience index monitoring is presented by using following indicators, namely: average wind velocity, power production, efficiency of electricity production, and power-frequency change. In evaluation of the resilience index of wind power plants special attention is devoted to the determination of the resilience index for situation with priority given to individual indicators.

To supply small cities with electric and thermal energy it is proposed to create selfcontained energy complex based on gas turbine plants (GTP), wind generators and electric storage cell. A scheme for the joint operation of these plants is offered, a methodology for calculating the quantitative characteristics of a wind power plant, gas turbines and electric storage cell is developed. Electric storage cell provide coverage the peak portion of the daily electrical load curve. The heat load is ensured by the operation of the waste-heat boiler and the peak boiler. Using the example of a power complex with an electric load of 5 MW and a heat load of 17.5 MW, the generation of electric energy by wind driven power plant and gas turbine plants, the supply of electric energy from electric storage cell, the heat loads of the waste-heat boiler and peak boiler by months of the year are calculated. When the power share of the wind power plant is 0.2, the electric storage cell provide for an annual period from 5.2 to 10.7 % of the daily demand of the electric load schedule. The electric power of the gas turbine plant in winter is reduced to 70 % of the maximum load of the consumer, in summer - up to 55 %. An increase in the relative share of the power of a WDPP reduces the electric capacity of a gas turbine plants, its cost, while the cost of electric storage cell increases.
