In this research, a study of solution to the problems of transmission in wind turbines, where the electronic appliances and gearboxes components responsible for much of the wind turbine problems as they increase the cost of operation and maintenance of wind turbines and here comes the role of variable transport systems ratios, which is a solution more efficient than in fixed proportions regimes where create a dynamic model of the turbine wind using the aerodynamic properties of the blade wind and calculate torque when the wind changing speeds values and this for each of the wind turbine with proportions variable order and fixed ratio using MATLAB software and after study shows that energy production is slightly higher and more importantly, so it is possible to say that the CVT system is a candidate to be the subject of research for future developments of the technology of wind turbines.

This paper treats the issue of wind energy storage, mechanically, using the flywheel device. We control the speed of the wind turbine and the flywheel by means of traditional PID controllers. These controllers are designed depending on the system m odel and its parameters. Speed control is achieved by electromagnetic rotor flux orientation as called vector control. Speed reference value of the wind turbine will be generated in order to track the maximum power point. The flywheel reference speed is generated based on a second order filter of power which is considered as a new contribution in this field of research. Frequency converters are not modeled but we only consider the control strategy. The results of modeling and simulation in Matlab satisfy the power smoothing issue and reflect the importance of this study.
Our research includes the transmission mechanism of the wind turbine and the calculation of losses, such as loss of mechanical ventilation and friction loss and the loss of lubrication between the gear teeth design. Aims and access to high reliabili ty work and thus obtain high efficiency and taking advantage of electronic programs, We observed that each type of previous losses have an impact on the overall loss of Gearbox, Depending on the working conditions, For example, at low speeds, loss of friction between the teeth is a great percentage of the total loss, And thus controls the overall efficiency of the transport system, while at high speeds noticed this low percentage of loss, while the loss of lubrication and ventilation rate rose.
It is the automatic control engineering knowledge forum, as it should monitor and control the variables that interact in all industrial processes to perform functions equipment installations constructed for her. The automatic control system techno logy has a big role in easing the burden of daily life, and make them more luxury. automatic control applications in most appliances, such as: air conditioning and stoves, washing machines, etc.Automated control concepts has been used in various areas of knowledge such as biology, economics, sociology, medicine and education .
This paper presents a strategy of variable speed wind turbine connected to a permanent magnet synchronous generator; the goal is to get the most possible wind turbines. We used a wind energy conversion system model consisting of a wind turbine, perma nent magnet synchronous generator, rectifier, buck-boost chopper, inverter, load, and traditional controller PI to stabilize the voltage obtained from the wind turbine and synchronous generator at a variable wind speed. Then we used one of the artificial intelligence techniques represented by the genetic algorithm to get the maximum possible wind turbine. The traditional controller PI and the genetic algorithm we modeled using the Matlab R2014a program and from it we obtained the advantages of mechanical power for wind turbine and determined maximum power points at each wind speed.
reliance on new and renewable sources of energy has grown in order to obtain electric power without the use of traditional fossil fuel sources. And thus solve the problems of the global energy crisis and also maintain a clean environment, through the fight against the dangers of global warming and its negative results Wind power is considered as one of the most important of these alternative energies. We will work in this research in order to be able to control wind turbine with variable speed through pitch angle control in order to organize power and control the rotational speed in order to make the power ideal. Where we will be using a fuzzy controller to control pitch angle instead of the traditional controllers, which is expected to improve system response and provide ease in the application and modification and reduction in the cost. By reference study we came to the result showing that most previous studies in advanced wind energy systems have addressed to control wind turbine using conventional controllers from PI or PID type. Show we have the problem of the need to know the exact mathematical model of the system. Where traditional controllers of wind turbines that operate at variable speed are based on mathematical models which may be complex and non-linear and neglect often physical phenomena, for example, magnetic saturation which leads to complexity in the calculation and unexpected performance of the driven system. The proposed research aims to provide a complete study through modeling and simulation using the Matlab about the use of fuzzy controller to control the wind turbine where traditional controllers of type PI will be designed to control the pitch angle and to control the rotational speed and fuzzy PI controllers to control the pitch angle. Results will be get and discussed and conclusion will be extracted from them. Research Results showed that the fuzzy control improves transient state behavior, but the steady-state behavior is better controlled when we use PI controller. So and based on the result we got, the PI controller can't be replaced actually with the fuzzy controller.
