ANT-400 Hydropower Station Solutions

Hydropower stations are categorized into low-voltage and high-voltage stations, though their automated control logic remains similar.
Hydropower Station Solutions cover core operations including measuring water levels and flow rates in inlet and outlet pools and controlling water gates. In high-voltage stations, a governor regulates turbine opening to automatically control generator power output; low-voltage stations adopt brushless or brushed excitation modes, with a controller managing generator output.

System Categories of Hydropower Station Solutions

• Low-Voltage Hydropower Stations: These utilize low-voltage generators and turbines combined with a “Four-in-One” integrated control panel (merging primary and secondary equipment). Generated power is stepped up via a transformer for high-voltage transmission. This setup involves automatic generation control, synchronization detection, step-up transformer protection panels, background monitoring systems, and mobile app integration.
• High-Voltage Hydropower Stations: These use comprehensive automation systems to control gate openings based on pool depth and flow, and utilize governors to adjust turbine blade openings for automatic power generation.
  The overall system provides effective monitoring of the power supply, relay protection, automation, dispatch communication, and auxiliary systems (oil, water, fire protection). It implements “Four Remote” functions (Control, Metering, Regulation, and Signaling) to achieve an automated microcomputer-based integrated protection and generation solution.
