SCADC system produced by TC HYDRO is used international standard, and all component are used Chinese quality brand or international brand(ABB, Siemens,Omron) etc.,This system includes: computer control system, LCU panel,public LCU panel, generator protection panel, transformer and line protection panel, DC power supply system(40Ah, 65Ah, 100Ah, 160Ah, 200Ah, 250Ah) and AC power supply panel.

 

 

GT8200 integrated automation system is a development and layered distributed computer monitoring system, the system is divided into two layers: power station grade and local control unit grade. The power station grade can be configured to single-machine, dual-machine or multi-machine system according to the scale of the power plant and its position in the grid and the functional requirements of the power station.The local control unit (LCU) grade can set up the unit LCU, switchyard LCU, public equipment LCU, gate LCU, etc.according to controlled object.The connection between the power station grade and the local control unit grade is used Ethernet connection conformed to the TCP/IP protocol.

It is mainly used for monitoring, acquisition, control and regulation during the production process of small and medium-sized unmanned operation (few people on duty) hydropower stations.

 

1.The monitoring system is designed in accordance with the principles of safety, reliability, economy, and practicality, and the overall design is based on the principle of unattended, few people on duty, reducing people and increasing efficiency.

2.The monitoring system adopts distributed opened type fast Ethernet network structure, and each computer hanging on the Ethernet adopts open system software.

3.The monitoring system is highly reliable, and it adopts a dual setting with the equipment closely related to the safe operation of the power plant . The partial failure of the monitoring system itself does not affect the normal operation of the local equipment.

4.Each unit of the monitoring system adopts standard modules, which can not only easy to update and expand  the functions and hardware,but also facilitate daily operation and maintenance. The modularization and structuring of the software  makes the system more adaptable to the increase of functions and the expansion of scale.

5.The system has good real-time performance and strong anti-interference ability.

6.The design of the monitoring system and the model selection of equipment conform to the development characteristics of the  computer, and make full use of the advanced technology in the computer field.

7.The main nodes and main hardware devices of the monitoring system are used redundant configured and are in hot-backup state, which makes the system highly reliability.

8.Each node in the monitoring system can operate independently, and the local control unit operates independently without affect by other nodes.

9.Communication between the power station and the cascade debugging center is convenient to realize the "four remotes" functions, and remotely and directly control and adjust to starting and stopping of the unit, load adjustment and switch operating.
