PLC Controlled Francis Hydro Turbine Generator Set IP54 Protection Microcomputer Governor for Hydropower Station

Automatic PLC Controlled Francis Hydro Turbine Generator Set

Our Automatic Francis Hydro Turbine Generator Set integrates a Programmable Logic Controller (PLC) governor with a microcomputer speed regulation system to deliver fully automated, unattended hydropower operation. Housed in an IP54 rated enclosure, this complete turbine-generator package is engineered for reliable, long-term performance in remote and harsh environments.

Key Features

• PLC Intelligent Governor: Advanced PLC-based speed governor with real-time frequency and load monitoring, automatic startup/shutdown sequences, and fault diagnostic capabilities.
• IP54 Protection Level: Dust-protected and splash-proof generator enclosure ensures reliable operation in humid powerhouse environments without additional weatherproofing structures.
• Microcomputer Speed Regulation: High-precision digital speed governor maintains stable frequency output (±0.5%) under fluctuating load conditions, ensuring grid compliance.
• Complete Generator Set Supply: Package includes Francis turbine runner, main shaft, guide vanes, inlet valve, synchronous generator, excitation system, governor cabinet, and control panel for turnkey installation.
• Static Excitation System: Thyristor-based static excitation with Automatic Voltage Regulator (AVR) delivers stable voltage output and rapid response to load changes.
• Remote Monitoring Ready: SCADA-compatible control interface enables remote operation, data logging, and real-time performance tracking via industrial communication protocols.

Technical Specifications

Automation & Control System Details

The integrated PLC governor system provides fully automatic operation including synchronized grid connection, active power regulation, reactive power compensation, and emergency shutdown with counter weight guide vane closure. The microcomputer speed governor continuously adjusts wicket gate opening to maintain optimal turbine speed under varying water flow conditions. All operational parameters are displayed on a touchscreen HMI panel with data logging capability for performance analysis.
