9、rol and supervision systems have proved very important in production systems. The need to acquire information to be placed in several locations at the same time, with real time results constantly increases the presen

10、ce of data communication networks in production processes, suggesting a ceaseless search for new techniques and ways of establishing this communication (CAPELLI, 2007). Research in several areas of energy production

11、 grew apace as the need for renewable energy sources arose. This form of sustainable development is outstanding for its low environmental impacts and an inexhaustible source of wind energy (BALARINE, 2009). In this a

12、rticle we present a study on a prototype of a system to acquire and monitor data using communication via PLC- Power Line Communication, applied to monitoring and supervising the rotor temperature of a small wind power

13、. The purpose is to acquire and analyze this information on wind power operation in order to generate rapid, reliable information providing an easily accessed data base. The data generated by the variable monitored w

14、ill be placed on the worldwide computer network, WEB, increasing the perception of the current status of the process, enabling the continuous evaluation of operational conditions without the need to travel to the are

15、a where the system is installed, thus reducing costs, response time, and action at a distance on the equipment monitored, as well as ensuring greater reliability of the results achieved. Distance monitoring aims at ma

17、ned allows diagnosing problems during a process and correcting them easily and speedily (BENAISSA et.al., 2004) I. OBJECTIVES AND MOTIVATION The motivation arose from previous research done at Universidade Federal do

18、 Rio Grande do Sul –UFRGS (Federal University of Rio Grande do Sul). It began with a project for the development of a small wind power for the Brazilian market. Once the research had been done, questions arose about

19、its maintenance. At this time, research began on how to monitor these small wind turbines, in line with the proposal of this study. The main objective of this work is to study and develop a system to acquire data, mon

20、itor and supervise the temperature of a small wind turbine rotor through a simulation prototype using the PLC Networks to communicate. The stages of this project can be seen in the flowchart below, by order of priori

21、ties envisioned: Monitoring the variable temperature of a wind power motor; Data acquisition using on-board systems; Transmission of the data on the variable monitored through the electricity grid; Management and sto

22、rage of data obtained using software; Posting on the world wide web; Implementation of distant control actions. 978-1-4673-2542-4/12/$31.00 ©2012 IEEE(1) I. DEVELOPMENT The layout of the prototype that can be seen

23、 in Figure 1 shows the temperature sensor, connected to the data acquisition board, which in turn consists of several components including the web microserver, which is connected to the computer by the PLC pairs, thr

24、ough the electricity grid. Figure 1- Model for the Experimental Procedure The prototype begins to operate by inserting a set point. This activates a green LED indicating the state of system normality, and the wind po

25、wer is switched on, and also an electricity grid which represents a network “fed” by it. Also, when the process begins, the temperature sensor is close to a power resistor which, when activated, begins to heat up, in

26、dicating a rise in temperature which can be seen on the HTML Page. On reaching the first temperature instituted by the set point, the green LED is switched off, i.e., the temperature is within an attention range; the

27、 power resistor will also continue to warm until it reaches the second temperature established. Now, the yellow LED switches off and is replaced by a red LED, which indicates that the system is in danger. Ventilation

28、 is activated by a cooler, to cool the power resistor, and the temperature of this resistor is automatically reduce. The red LED is switched off and the yellow returns, again indicating a state of alert. The mini wind

29、 turbine and its electric system are also switched off. The ventilation system will work until it reaches the initial temperature of the set point which, once reached, switches off the entire system. Through this las

30、t command, it is possible to establish a new set point and a new process begins. Figure 2 – Prototype of the simulation of a wind turbine in operation II. CONCLUSIONS AND FINAL CONSIDERATIONS The use of sensors togeth

31、er with other applications was an important tool for the diagnosis of non conformities and problems in the process. The study also confirms the ease of remote interactions with equipment, using PLC technology, beside

32、s allowed a series of possible applications in different fields of activity. It is also considered that the PLC technology performed well under the conditions in which it was tested, proving its efficiency and the p

33、ossibility of use in the different segments of remote monitoring. As to remote monitoring, this means a saving (cost reduction) in measurement and sensoring, since it avoids frequent travel by the technicians to the

34、 physical site of the sensors or the plant, and also because it uses an already existing transmission medium, in this case the electricity grid, making it possible to reduce the costs for investment in a possible imp

35、lantation in remote sites. Applying a remote system for data acquisition and transmission is also a factor that increases reliability and operational convenience. Based on its application, the performance of any syste

36、m can be followed remotely. AUTHORS M. Rosa, is a master‘s student at Universidade Federal do Rio Grande do Sul (UFRGS), Porto Alegre, Brazil. (e- mail: magali.rosa@satc.edu.br). R. Marcelino, is a researcher at Univ
