Carioca VLT

Power Substation Control Solution for VLT Carioca

Altus was responsible for the development and implementation of the control system for the 14 power substations of the VLT Carioca, a modern and sustainable public transportation system implemented in the city of Rio de Janeiro.

Control System for Itaquera and Belém Yards

Each substation was equipped with a Control and Automation Cubicle (CCA), responsible for collecting essential process data and converting protocols using a Hadron Xtorm Remote Terminal Unit (RTU). The converted data is then sent to the Operations Control Center (CCO), which manages all substations as well as the traffic and signaling systems.

Local and remote supervision with Altus technology

Local and remote supervision with Altus technology

Each substation can be supervised and controlled locally through the HMI installed in the CCA or remotely via the CCO. The local HMI uses a SCADA system developed with Altus' BluePlant software. Both the local SCADA (CCA) and the remote supervisory system (CCO) communicate with Intelligent Electronic Devices (IEDs) via the IEC 61850 protocol.

A set of optimized solutions was created to control and monitor the medium-voltage system and integrate the traction system with the Operations Control Center, using cutting-edge tools for energy sector process monitoring and supervision.

Project Scope: Hardware and Services

Project Scope: Hardware and Services

The project included the supply and installation of 14 Control and Automation Cubicles (CCA), 14 Remote Terminal Units (RTU), 15 TouchScreen Human-Machine Interfaces (HMI), and 5 Logger SSU ABNT CODI 14522 – Modbus RTU Converters.

The system scope covers control and automation panels, electrical design, network architecture, SCADA system development via BluePlant, integration with field equipment like protection relays, UPS units, energy meters, and rectifiers, as well as configuration, parameterization, and testing of medium-voltage protection relays. It also includes the development of the IEC 61850 network, OPC server configuration, SCADA system integration with the CCO, system startup, and training for operations and maintenance.

Nexto HX Technology-Based Solution

Nexto HX Technology-Based Solution

The application created for the project utilizes the technology of the HX Series, Altus' remote terminal units for use in power generation, transmission, and distribution systems, and the Blueplant SCADA/HMI supervisory software. Developed based on the international standards IEC 61850 and IEC 61131-3, the HX products feature outstanding functionalities such as power supply redundancy, CPU redundancy in a rack, DNP3 and IEC 61850 protocols (MMS and GOOSE), and compliance with ONS sub-module 2.7. Being a modular architecture solution, the RTU provides a wide variety of input and output modules that, combined with its powerful 32-bit CPU and a high-speed deterministic Ethernet-based bus, meet the requirements of diverse applications.
