ArcelorMittal Tubarão - 2021
Objective: replacement of the current SGCE EMS (Energy Management and Control System) by SCADA Action.NET.
The supply includes software engineering, migration of telemetering and remote control communication parameters, design and development of HMI (Human-Machine Interface) and application functions, factory acceptance tests, survey and validation of installed systems with respective functionalities (field) , supply of drawings and documentation – identification and information for ArcelorMittal Tubarão to carry out revisions of drawings and documents, assembly, site tests, commissioning, assisted operation and training in operation and maintenance.
SGCE operates three 138kV substations, one 34.5kV substation and eleven 13.8kV substations that supply the entire ArcelorMittal Tubarão plant. All existing substations are integrated through the SRTP GE Fanuc protocol.
As an additional scope, a DTS (Dispatcher Training System) will be provided and the entry of one more 138kV substation is planned to be integrated into the new SGCE, following the IEC 61850 standard.
Methodology, updates, import and database
Methodology and updates
The methodology used in the updates consists of analyzing the existing database through a backup sent by the client, creating the points in a parallel database and studying what already exists, but it will need to undergo changes, such as the inclusion of bays on the screens of single-lines, or rename bays in case of sectioning. This entire process is done prior to testing.
Import and database
In loco, the new points are imported into the database that is in the production environment and the necessary changes, previously raised, are carried out. This procedure guarantees that no changes made by the maintenance teams, in the time interval for setting up the new points, are lost. Or even that the customer has complete freedom to modify the local database, regardless of the project schedule.
Project phases
The project is in the initial phase of implementation, with final implementation in 2022, where the modeling of the SGCE database is developed and the import of existing data in the system is carried out.

ArcelorMittal Tubarão has with the project a modern software platform capable of supporting the updates foreseen in its substations for several years.
High performance: HMI screens (Human-Machine interfaces)
Business Rules Management
Increasing the resilience of the SGCE
Increase in communication reliability
Better negative impact management for system operation
High performance: HMI screens (Human-Machine interfaces)
The new HMI (Human-Machine Interfaces) screens will be developed following high-performance concepts, with the aim of increasing the effectiveness of process monitoring and improving the operators’ reaction time in face of abnormal situations.
Business Rules Management
The SGCE also incorporates Business Rules Management, such as monitoring of Demand Control, Power Factor Control in the integration with the energy supplier concessionaire, Busbar Control, Totalizations of energy generation and consumption and variable calculations – key in helping the operation to ensure the stability of the 138kV buses in case of eventual disconnections caused by occurrences in the SIN (National Interconnected System). The system will also provide specific information on measurements and status of the Electric System, for the purpose of preparing management data and business production bulletins.
Increasing the resilience of the SGCE
The entire application (real-time servers operating in hotstandby, Oracle historical server, operation consoles, DTS server and training console) will be installed in a virtualized environment with redundancy between Data Centers. This architecture increases the resiliency of the SGCE.
Increase in communication reliability
The dedicated ICCP server for sending data to the ONS (National System Operator) will be migrated to ICCP SPIN-Action.NET, adding redundancy and increasing communication reliability.
Better negative impact management for system operation
During the entire migration process, Action.Net works in parallel with the current SGCE system, mitigating any type of negative impact on the system’s operation, such as loss of supervision.
