Segment: Energy Companies: scadaHUB for ENGIE Brasil Energia Country: Brazil

scadaHUB is focused in SCADA systems and has a strong presence in the power sector, especially in generation and distribution.

Summary THE SCADA System PROVIDES MORE RELIABILITY AND SPEED TO ENGIE BRASIL’S MONITORING AND CONTROL SYSTEM • 32 plants monitored • 06 plants remotely operated • 7.69 GW of generating capacity • 6% of the country’s installed capacity

Demand ENGIE Brasil Energia is Brazil’s largest private power company, with 7069MW of installed capacity. The company needed to centralize the operation of its assets, seeking not only to remotely operate the plants, but also to coordinate and monitor their activities.

Solution The process began with the creation of the SOC - System Operation Center and later with the GOC – Power Generation Operation Center. Although their purposes are very similar and they are operated from the same location, the systems have different focuses and teams.

The SOC was created to address the need to centralize scheduling interventions, plant dispatch, coordination of operational aspects (unit synchronization, generator/compensator conversion, Automatic Generation Control (AGC), daily schedule execution, active/reactive voltage control and switch of generating units), management of the relationship between the plants and the Operator of the National Electricity System (ONS), as well as monitoring the plants’ performance. For the SOC, the SCADA Elipse E3 system was used, with the application developed by scadaHUB Tecnologia. The SOC has a gateway (also developed with Elipse) in a demilitarized zone, where the plants data are collected. From the gateway the information goes to the SCADA main servers, which allow operators to monitor all of ENGIE Brasil Energia’s assets at its headquarters in Florianópolis/SC. The application has approximately 180,000 points, and uses the IEC 60870-5- 104 and DNP 3.0 protocols (in addition to the protocol Remote Domains of Elipse software) in secure networks without external access or through the company’s corporate network.

For the GOC, the focus was the remote control of the plants, aiming to centralize their operation in ENGIE’s Operation Center. The work began in 2016 with the Ponte de Pedra HPP, a plant with an installed capacity of 176 MW, and the José Gelázio and Rondonópolis SHPs, small plants that were already operated remotely from the Ponte de Pedra HPP control room. Similarly, to the work that was done with the SOC, ENGIE prepared a demilitarized zone to collect data from the units. The same level of security was also applied in the field. With work coordinated by the company’s Operations Department, the project was attended by the IT team, field operators and the scadaHUB development team. This work involved not only the creation of the new monitoring system, but also the substitution of the local SCADA for the new system. Remote and local SCADAs have the same displays and logic of operation, plus a protection mechanism that prevents both levels from sending commands at the same time. As with the SOC system, the displays were designed together with scadaHUB adopting the high-performance HMI practice set, looking for pleasing and objective screens without causing confusion of readability and commands. In addition to the initial units, the system now has the operation of the Cana Brava (450 MW) and São Salvador (243 MW) plants. The GOC has about 250,000 points, distributed in a set of servers that use the protocols IEC 60970-5- 104 and DNP 3.0, in addition to the protocol Remote Domains of Elipse Software.

Partnership scadaHUB / ENGIE Brasil Energia scadaHUB is ENGIE’s partner to develop SCADA systems and worked since the beginning of this project assisting in the description and design of SCADA solutions. This system is designed to provide operational availability and robustness, as well as a standardized high-performance interface according to ENGIE’s interface guidelines. It allows the assets to be easily identified independently without each having to follow its own design standard.

Benefits The set of systems for the SOC and GOC brought a series of benefits that aimed to reach the demand of the company, highlighting: • Greater availability and reliability in resources for monitoring and control of plants; • Improvement in maintenance processes.
