Nilo Pecanha HPP

DCS Modernization

Altus was selected to retrofit the Digital Supervision and Control System at the Nilo Peçanha Hydroelectric Plant.

Developing the New Digital Supervision and Control System

Inaugurated in 1953, the Nilo Peçanha Hydroelectric Plant is part of the Lajes Hydroelectric Complex, located in Piraí, Rio de Janeiro. With six generating units and a 312-meter drop, the plant has an installed capacity of 380 MW.

Em 2016, a Light Energia iniciou o processo de modernização do Sistema Digital de Supervisão e Controle da usina utilizando a tecnologia dos produtos HX. O projeto inclui lógicas de aquisição e controle e um novo sistema supervisório, além de disponibilizar o controle e supervisão ao COG Light no Rio de Janeiro/RJ.

Remote Supervision and Control

Reduction in space and wiring, resulting in increased reliability, cost savings, and enhanced supervision and control capabilities

Enhanced Productivity

Boosted operational efficiency across the entire system, lowering costs and improving response times

Reliability and Durability

A robust communication system with enhanced diagnostics. An open, easy-to-maintain supervisory system

High Availability

Minimized downtime through fast fault detection and identification

Solução de Supervisão e Controle de Processos

Process Supervision and Control Solution

A typical UAC architecture features a main rack with 18 HX9103 modules, 2 redundant HX8320 power supplies (125VDC), and 2 redundant HX3040 processors communicating via DNP3 Ethernet protocol. It also includes 12 digital input cards (125VDC) with 32 inputs each, and 2 HX9102 side covers.

The second rack, also an HX9103 model, includes 2 HX8320 power supplies, which connect to other racks via 2 NX9205 cables, 3 HX1120 cards, 4 HX2320 digital output cards (125VDC) with 16 outputs each, and 7 HX6000 analog cards configurable for current or voltage input, with 16 inputs each, plus 2 HX9102 side covers.

The third 9-slot HX9101 rack includes two HX8320 power supplies connected via 2 NX9205 cables, 6 HX6020 RTD input modules with 8 inputs each, and 1 HX9102 side cover. Each HX3040 CPU connects to its respective RS900 switch via an Ethernet port. These CPUs receive IRIG-B synchronization through an optical-to-electrical IRIG-B signal converter (RT-412) from Reason. The CPUs also receive MODBUS-RTU signals from the electrical measurement meters. The speed and voltage regulators are each connected to a switch on the panel.

Reliable Communication Networks

The topology incorporates a dual redundant ring network to maximize availability. Special switches with dual optical ports interconnect the rings, ensuring that the plant continues operating through the redundant ring in the event of a failure on one side

System Highlights

- Event logging with 1ms precision for all digital input points

- Event logging with 100ms precision for all analog input points

- A dual redundant optical ring network for enhanced security and improved communication between UAs (Autonomous Units) and the supervisory system

- Redundant servers for the supervisory system

- Redundant database system

- Satellite (GPS) synchronization of UAs

- Provision of data and event information to ONS

- Oscillography and monitoring system

- Redundant protection relays
