Hydroteck Control is a compact solution permitting the automatic and manual control of a small hydroelectric unit while ensuring the safety of the facility.

The controls, the start and stop sequences, the human-machine interface, the turbine governor and voltage regulator as well as the electrical and mechanical protection systems are included in this package.


  • global study, functional analysis, electrical schematics
  • design of the protection systems (redundant or by loss of voltage)
  • simulation of the turbine dynamics and the governor system with Matlab
  • software programming on Schneider or Siemens PLC’s
  • turbine regulating modes : opening, speed, power, frequency, level and flow control
  • voltage regulating modes : reactive power control power factor control with limiters PQ, stator current, over and under voltage and V/Hz
  • electrical protection functions : overcurrent, thermal, asymmetry, over/under voltage, over/under frequency
  • commissioning using procedures and check lists ensuring the safety of the facility and individuals
