Siemens provides CELPA Brazil with 12 microgrids


According to a company release, the microgrids will be built in CELPA power generation plants in the state of Pará. A central control center in Belém will monitor and control the self-contained island networks.

Siemens will deliver and install the automation, protection and control technology, which will improve the analysis of plant data and thus increase the availability and reliability of the plants. Additionally, these insights will allow CELPA to optimise and better plan the service and maintenance work of field service teams, so that fewer deployments on site are necessary.

The scope of delivery to CELPA also includes the provision of RTUs (remote terminal units) and the communication interfaces. The protection technology components are supplied by Reyrolle. A monitoring station where all data can be viewed will be installed in each of the 12 plants. Monitoring of all plants will be carried out by a control center based on Sicam SCC. Siemens is to install and set the parameters of all components of the microgrid and will also provide service and training for the plant operators.

Two of the power plants are 890 kilometers away from each other, while the balance are geographically distributed across the state of Pará.

According to Siemens’,  “The plants are located in Afuá, Alenquer, Faro, Gurupá, Juruti, Monte Alegre, Muaná, Oeiras do Pará, Porto de Moz, Prainha, São Sebastião da Boa Vista and Terra Santa. The region in which the plants are located features rough and almost impassable terrain, and is mainly accessible by river. From Belém to Terra Santa takes about seven days by boat.”

“We offer a complete, easy-to-operate system for simple and reliable energy management. In this way we can improve monitoring and control systems and thus increase generation rates, while reducing fuel consumption and improving the reliability of the plants. Another advantage of this system is that down-times are reduced and the plants can be operated with the highest efficiency parameters,” states Sérgio Jacobsen, CEO of Siemens Digital Grid in Brazil.
