CLIC Energia publishes the twenty-fifth of 30 projects selected for the 4th Edition of R&D Magazine, launched 8/17/2011, during the VI Congress on Technological Innovation in Electrical Energy (CITENEL) and the II Energy Efficiency Seminar in the Electric Sector (SEENEL), held in Fortaleza (CE).The objective is to show society the results achieved with R&D projects.The onsite publication accompanies the order used in the magazine.
The twenty-fifth article is about a portable voltage regulator for low voltage grids (RTPBT) developed by researchers from AES Eletropaulo, the Foundation for Engineering Technological Development and Sinapsis Innovation in Energy.The device will be used to adjust the power input voltage provided low voltage consumers by adding or subtracting the proper voltage so that, at the exit it remains within the limits established by the Brazilian Electricity Regulatory Agency (ANEEL).The measurement and evaluation of the voltage level are services that can be requested by consumers to the power distributor, and the companies are obliged to identify and solve the problem within a period specified by the Agency. At times, this was not possible due to the intervention needed.After the successful lab tests, AES Eletropaulo used the regulator meter during a real case involving voltage complaints, with satisfactory results. After conclusion of the project, the device is being used by the distributor for voltage complaint cases. A patent has been requested and industrial production has begun.

Portable voltage regulator keeps supply within required standards
A portable voltage regulator for low voltage grids (RTPBT) has been developed by researchers from AES Eletropaulo, the Foundation for Engineering Technological Development and Sinapsis Innovation in Energy.The equipment aims to keep the voltage provided to consumers within the limits established by the Brazilian Electricity Regulatory Agency (ANEEL).According to the regulation, consumers can ask the distributors to measure and evaluate the voltage level when they notice the energy has been provided outside the proper range.In such cases, the companies are obliged to identify and solve the problem within a period specified by the Agency, which is not always feasible due to the needed intervention.Researchers believe that in these cases, the portable regulator can be used successfully.The equipment permits adjusting power input voltage by adding or subtracting the proper voltage quantity so that, at exit, the voltage is kept within a level considered proper by current regulations.The product was developed in four stages:methodology for project development, projected hardware, lab tests and, finally, real case application.In all tests conducted, the results showed that the voltage range considered proper at the regulator output was kept within the limits.In the end, the concessionaire used the RTPBT to service a real voltage complaint case.The researchers concluded that the equipment behaved in a fully satisfactory manner, fulfilling objectives, which is why it is now in use at AES Eletropaulo.After conclusion of the project, a patent was requested and a new project initiated, corresponding to the manufacturing of a serially produced head for industrializing the device.
