The most critical component of a wind power plant is the transmission line, which carries two key tasks – the transpor-tation and distribution of electricity. The transmission line is also responsible for the various substations, wind power stations to contact to its safe and smooth operation. As the competition order of wind power projects is more chaotic, the quality of the project cannot be supervised and controlled by the whole process. The quality control of the project is not up to standard, and the overall quality of the transmission line will be affected. This paper focuses on two aspects of the elaboration, one is the wind turbine transmission line project common quality problems; the other is how to build wind power plant transmission line quality assurance system.

The simple principle of wind power plant is use wind as main exciter to rotate the turbine. The turbine convert wind to electric energy. The output signal is alternating (AC) current. This current was changed to direct current (DC) by rectifier circuit. The DC current was used as charge the energy storage, battery. Next step, the DC current from battery convert to AC current using inverter circuit. The result of inverter shows that the error is 20% with 240V no load.

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.

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.

Design Structure

The purpose of the work is to select the design concept of the wind power plant and the method of transformation of mechanical wind energy into electric energy depending on the wind speed in the given area. In order to solve the first task, it is proposed to approximate the distribution of wind speed with the help of the Raleigh Law, to use incomplete gamma functions and to compare the average annual power of wind plants with the vertical and horizontal spin axis. At low wind speeds dependence of wind plant mass with vertical spin axis with different types of generators is analyzed. The multiplication unit design is selected. Friction forces are determined in planetary multiplication unit having high efficiency. The effect of these forces on wind power plant efficiency is analyzed.
