Some chats about the hydropower

Hometown
In my hometown have the largest hydropower station in the world. I often go to the Three Gorges and Gezhouba Dam in my childhood.
This city is Hubei Yichang,a beautiful and comfortable tourist city.

Three Gorges
At that time, many small partners lived in a large yard.Their father and mother are Three Gorges Group or Gezhouba Dam or The State Grid.They spent a wonderful childhood with me.

Gezhouba Dam
In the evening, I will have a barbecue on a walk along the river with my friends. At weekends, there are many tourist resources in Yichang.
That time really worth me to memorize.
The time less than twenty years is really worth me remembering.
Next, I will slowly fill this article, because the author develops more business, please be patient.
SCADA
Supervisory control and data acquisition (SCADA) is a control system architecture that uses computers, networked data communications and graphical user interfaces for high-level process supervisory management, but uses other peripheral devices such as programmable logic controllers and discrete PID controllers to interface to the process plant or machinery. The operator interfaces which enable monitoring and the issuing of process commands, such as controller set point changes, are handled through the SCADA computer system. However, the real-time control logic or controller calculations are performed by networked modules which connect to the field sensors and actuators.

China Scada
Fuchunjiang took the lead in success,Gezhouba was subsequently invested successfully.
IWHR and NR to learn from foreign advanced technology hydropower plant computer monitoring system,Developed its own intellectual property monitoring system and began to promote its application in China. The Institute of Water Sciences has introduced H9000V1/V2/V3/V4, NJ's SJ-400, SJ-500, SJ-600, EC2000 (based on Windows NT), and NC2000 (based on UNIX).
Hydropower station computer monitoring system
The hydropower station computer monitoring system adopts an open hierarchical distributed structure, and the overall structure is divided into two layers: the whole plant control layer and the local control layer. The control layer of the whole plant mainly includes: operator station, engineer station, dispatching communication server, data server, satellite time-to-time system, related network equipment and network security equipment. The local control layer mainly includes: the local control unit of the unit, the local control unit of the switch station, the local control unit of the public equipment, and the local control unit of the gate.
The main components of the local control unit: main controller: programmable logic controller (PLC); local man-machine interface: touch screen; communication management device: MOXA UC-7410; intelligent acquisition instrument: AC sampling table, Multi-function watt-hour meter, etc.
