Renewable energy is the development tendency in the future. Its not only save energy but also protect the environment. And the wind power generation has more competitive potential compared with other renewable energy, so it develops so quickly. According to the bad environment of the wind farms, wind turbines control system requires multipoint, high speed and real-time communication. This paper puts forward a kind of wind turbines control system based on the CAN bus architecture and realizes the real-time communication and decentralized control between the master control system and submodule. This paper analyses the system structure, the hardware composition of control module, the expansion of CAN bus, the communication mechanism in master-slave module.

In order to meet the increasing requirements for express elevator control system and its intelligence and security, ARM chip is applied to construct hardware platform of elevator's main-board in this paper. BootLoader and the uCLinux are transplanted to this platform, and CAN-Bus and other related drivers are designed. A single elevator's operation algorithm is presented to achieve the elevator control logic. And the store and access of parameters of elevator are accomplished by real-time SQLite database. The main high-speed counting circuit is designed based on CPLD while the auxiliary one is based on AVR MCU, which guarantee the stability and reliability of the system. The operational results in elevator simulator verify the feasibility and efficiency of the control system.

Abstract Energy production by wind turbines has many advantages. The wind is a renewable energy that does not emit greenhouse gases and has caused a considerable increase in wind farms around the world. However, this type of energy is not completely free of impact. In particular, wind turbines displace and kill a wide variety of wild species what forces us to plan their location well. In any case, the determination of the effects of wind farms on fauna, especially the flying one, is difficult to determine and depends on several factors. In this work, we will try to establish a mathematical algorithm that allows us to combine all variables that affect the species with the idea of quantifying the effect that can cause the installation of a wind farm with certain characteristics in a given place. We have considered specific parameters of wind farms, the most relevant environmental characteristics related to the location of the wind farm, and morphological, ethological and legal characteristics in the species. Two types of assessment are established for the definitive valuation. Total Assessment and Weighted Assessment. Total Valuation is established based on a reference scale that will allow us to establish categories of affection for the different species while Weighted valuation allows us to establish which species are most affected.

In order to fulfil the European Energy Performance of Buildings Directive (EPBD) requirements regarding the reduction of energy consumption in buildings, much attention has been paid to primary energy consumption. Wind energy is one type of primary energy. The analysis of the literature has revealed that wind energy is evaluated by different methods. Therefore, the aim of this article was to calculate the effect of the parameters of wind sources on the primary energy factor of wind turbines. In order to achieve this aim, the primary energy factor of 100 investigated wind turbines and 11 wind farms operating in Lithuania was calculated. Investigation results showed that the difference of the non-renewable primary energy factor between wind turbines due to capacity is 35%. This paper provides a recommendation with regard to EU energy efficiency and renewable energy directives and regulations: All EU member states should use the same or very similar methodology for the calculation of the primary energy factor of renewable and non-renewable energy sources.
