In this paper, the technical and economic feasibility of innovative renewable energy systems, solar wind hybrid power generation capability is provided for collecting rainwater. Part of the energy required for tall buildings where the system is installed it provides. The system is compact and can be built on top of tall buildings and the construction of renewable energy required in the space provided. PAGV shape and appearance of the surrounding wind turbines can be combined with the architecture of the building and no negative impact on demand. (Part of the building). This design improves the starting behavior of wind turbines. Also for the people around safer and reduces noise pollution. Technical and economic analysis was conducted using life cycle cost. (LCC) LCC method, taking into account the full range of costs and cash flow of time makes the cost equation. Evaluations show that for a PAVG (with a diameter of 30 m and height 14 m) and wind turbine rotor vertical H- axis (diameter 17 mm and a height of 9 m) mounted on top of the building with 60 meters high, the estimated energy savings annual 195.2mwh/year.

With the increasing dependence on electrical power generation resources, achieve a good level of reliability, quality and safety, along with cost-efficient day to day for consumers is more important Another necessary thing that should take into consideration the safety of electric power.One of the first requirements of each feeding system is that such a system be designed well and in the next step be to good maintenance until the number of errors that might occur, it is limited. In this article, we try to have a variety of errors found in the distribution system should be evaluated and appropriate with such a solution provides dynamic protection of these errors as much as possible to a minimum of time.

In this paper a method for automatic power regulation, with the Elimination of the two-mass system provide winding of volatility has been eaten. Intensification ratio control method is effective in controlling system of two mass. Intensification ratio control method is effective in controlling system of two mass. In this method, the intensification of the frequency ratio between the motor and the shaft torque feedback automatically according to the image (s) have been estimated for reaction with the torque reactions are determined by a clear picture-maker is estimated position (PSD). Accordingly, in estimating the parameters do not need to diagnostic and information with particular accuracy of bolt corrosion in the hands of will. Move the system to be compatible with the environment by having a torque reaction force sensor, a picture can be observed. Automatic power regulation system based on PD control than conventional and controlling is intensifying. In this article, determine the method of optimum PMU pole studied and are caused by the environment, the control of producer-driven disorders by observation axis and will discussed without it. Automatic power regulation system, proposed in the present article, may be narrow and quench internal screw Torque with recipe and photos are also eaten with input of external resources to match the unknown forgive fulfillment. The results of numerical simulation and the possibility of combining the proposed method shows.

The production of energy is not a new term scattered. The traditional structure of the electric power industry has always been based on the absence of active electrical energy production resources in a distributed network, has been based. By increasing the amount of installed capacity, production and these resources because of the different technologies in the construction and use of productive resources, the effects of such resources in parallel operation and connect them with the distribution network to prevent degradation of power quality, reliability and the ability to control the distribution network is very important.

Incorporated in electrical systems, electrical energy in the form of large central power stations by takes place. In the early years of the emergence of continuous systems, usually with annual growth of about 6 to 7 percent in electric energy consumption was met. In the 1970's oil crisis issues, such as environmental issues and new problems for the electrical industry expressed, in such a way that in the1980s the invoices and the economic changes, resulting in a reduction of approximately 1.6 times growth to 3 percent per year, respectively. At the same time the cost of transmission and distribution of electric energy as well as to increased significantly. Therefore, the production of large central power stations by, often due to the cost increase slowdown time, transmission and distribution, getting acute environmental issues and technological changes and different legislation were impractical. In this article, we try to study the general definition has been scattered resources will be carried out in different countries, then the evaluation of the benefits and disadvantages of them.
