EGAT SIRINDHON HYDRO POWER PLANT
- 7 Redundant PLC RX3i Stations
- iFix HMI SCADA
Hydro Power Plant
Comprising key components such as the spillway, powerhouse, high-voltage transformers, and the substation integrated with the national transmission grid. The entire facility is engineered to operate with seamless integration of mechanical, electrical, and Automatic Control Systems to ensure stable, safe, and highly efficient electricity generation.
Planning and Design Process
Prior to implementation, the project involved structured engineering planning sessions where expert teams analyzed load demand, designed single line diagrams, and established safety and protection coordination measures. Additionally, a comprehensive on-site survey was conducted to assess terrain conditions, cable routing, drainage systems, and civil structures to ensure compliance with international engineering standards (IEC, IEEE).
Integration of Automatic Control System
The plant employs advanced Automatic Control System technologies, primarily managed through SCADA (Supervisory Control and Data Acquisition) for real-time monitoring and remote operation, connected with PLC (Programmable Logic Controllers) that directly control electromechanical equipment such as gate operations, turbine regulation, and generator control.
● Hardware: Includes Remote I/O Modules, fiber-optic communication networks, electrical sensors for voltage/current monitoring, and system protection devices.
● Software: SCADA software is integrated with HMI (Human-Machine Interfaces), enabling engineers and operators to visualize data, analyze system behavior, and execute corrective actions with precision.
