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.

Solução de Supervisão e Controle de Processos

Process Supervision and Control Solution

A arquitetura típica de uma UAC é composta por um bastidor principal de 18 posições o HX9003 que pode conter até 02 fontes redundantes HX8320 em 125Vcc, 02 unidades de processamento redundantes HX3040, que comunicam via protocolo ethernet DNP3 e 12 cartões de entrada digitais o HX1120 com 32 entradas digitais. Cada CPU se conecta à uma porta ethernet em seu respectivo switch RS900, dispostos em anel redundante na rede de automação. Estas CPUs recebem sincronismo IRIG-B através do conversor de sinal IRIG-B óptico para IRIG-B elétrico RT-412 da Reason. As CPUs também recebem sinal MODBUS-RTU do multimedidor de grandezas elétricas. O regulador de velocidade e o regulador de tensão são conectados cada um em um switch do painel.

O segundo bastidor, também um modelo HX9003, possui 02 fontes HX8320, que fazem a conexão da expansão com os outros bastidores via 02 cabos padrão ethernet, 03 cartões HX1120, 04 cartões de saída digital em HX2320 com 16 saídas cada, 07 cartões analógicos HX6000, configuráveis com entrada a corrente ou tensão com 16 entradas.

O terceiro bastidor de 9 posições HX9001 possui duas fontes HX8320 conectadas através de 02 cabos ethernet, 06 módulos de entrada RTD HX6020 com 8 entradas cada.

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
