Governor

Governors for Hydro Power Plants

  • Design based on IEC and IEEE Standards;
  • Suitable for use in hydro power plant with all type of Turbines (Francis, Pelton, Banki, axial and …);
  • Defferent operational Control modes (Power, Speed, opening , Island, Water level and flow control Modes);
  • Can be delivered in two type:
         Electrohydraulic Governor(for conventional hydro power plant),
        Thermal Governor(for small power plant under 100KW suitable for black starting and operating in island networks);
  • Using qualified components;
  • Tested with high accuracy power plant simulator.

 

Main Characteristics:

  • Control Panel with PLC S7-300, S7-400 (SIEMENS) with hot and warm redundancy for more reliability;
  • Separate speed card able to produce 8 speed thresholds;
  • Capability of adjustment & locking of servomotors’ speed mechanically;
  • Hydraulic system with redundancy;
  • Using mechanical and electrical overspeed;
  • Using air/oil pressure vessel;
  • Installation, commissioning and training services;
  • Spare Parts;
  • Can be delivered within 6 to 12 months according to size of power plant;
  • 1 year guarantee and 10 years after sale service.
