The energy transition to the growth of renewable energies necessarily involves smart grids, smart grids, with automated equipment that allows efficient control of the various flows of electricity. Aligned with its strategy of contributing to decarbonization and innovation in the sector, Neoenergia is developing intelligent sensors for 69 kV, high voltage electric grids, with national technology. The initiative is part of the Research and Development (R&D) program,regulated by the National Electric Energy Agency (ANEEL), and has as partners in this project the Lactec Institute and Tecsys.
The sensors created in the project monitor the main information of the lines, such as current, power factor and surge current. In addition, they automatically identify power outages. 'Our goal is to develop a national technology that accelerates the process of modernizing our networks and contributes to innovation in the national electricity sector. This smart sensor has among its advantages to improve the quality of services for customers, since it allows the solution of problems quickly and assertively', saysthe corporate manager of Research and Development of Neoenergia, José Antonio Brito.
The device consists of three sensors, one for each phase of the electrical network, and a concentrator unit, installed on the pole or structure of the transmission line. Sensors and the hub communicate by radio frequency. The concentrator periodically sends all information measured by the set to the Operations Center, through cellular network, radio, satellite or fiber optics.
The first equipment for testing has already been installed in the municipality of Barreiras by Coelba,a distributor of Neoenergia that operates in Bahia. Another nine units will be tested, the next in Itapeva and Votuporanga, cities in São Paulo that are in the concession area of Elektro.
The equipment sends to the distributor's Operations Center an alarm of power outages or any problems. This alert points to the exact location, leading to a more responsive resolution. In addition, the national technology being developed by Neoenergia, sends information about the network periodically for monitoring, a differential, since other models available in the market, in general, indicate only the lack of energy. The sensor also informs your operating conditions, such as battery charge status and maintenance alarms.
With this data, the distributor can act faster if there is a network problem, reducing downtime. Thus, the use of the sensor can reflect on the improvement of the quality of services, represented by the indicators established by the regulatory body: DEC (Equivalent Interruption Duration) and FEC (Equivalent Frequency of Interruption), that is, time and frequency that consumers are without the service if there is a failure. In addition, with the monitoring of data about the network in an automated way, the new equipment allows the measurement of electrical losses.
Medium voltage
In another project, Neoenergia developed a pioneering model of intelligent sensor for medium voltage networks, up to 34.5 kV, which began its commercialization in 2016. Today, the company already has 2,245 sets of smart sensors installed in four distributors, 1,359 at Coelba, 574 at Celpe, 140 at Cosern and 172 at Elektro. 'Our goal is to foster the development of technologies that can be used by both our concessionaires and the market, contributing to the national electricity sector by creating efficient products with lower costs,' says José Antonio Brito.
The two initiatives are part of a Neoenergia project for the development of national technology for intelligent electrical networks, which encompassesproducts such as the qualmeter,< /a>equipment to measure the quality of energy delivered to customers, or the multilink concentrator,a device that serves as a link between equipment in the field and the operation centers and datacenters.
