Control and automation systems

The “Automation & Control” department at JLA Hydro is able to support you with the automation of your hydroelectric power plant, including:

Electronic speed control with remote-control turbine gates

This system makes it possible to control the speed of the turbo-generator group, by controlling the turbine vanes opening. It is used for:

  • Controlling the frequency of turbo-generator groups not connected to the national grid
  • Connecting turbo-generator groups to the national grid

Main characteristics:

  • PID regulation algorithm, whose parameters are adjusted according to the inertia of the turbo-generator group
  • Contactless speed measurement
  • Easily-adjustable settings and control parameters
  • Control of hydraulic or electric actuators
  • Optimised efficiency by intelligent turbine vane opening for PLC-controlled systems
  • Standard design, which facilitates the supply of replacement parts

Electronic speed control with load control: Electronic Load Controller

This system makes it possible to control the turbo-generator group speed, by controlling the electrical load applied to the alternator. It is used for:

  • Regulating the frequency of the turbo-generator groups not connected to the national grid
  • Connecting turbo-generator groups to the national grid

Main characteristics:

  • Controlling the frequency of the turbo-generator groups not connected to the national grid
  • Connecting turbo-generator groups to the national grid
  • PID regulation algorithm, whose parameters are adjusted according to the inertia of the turbo-generator group
  • Regulation by energy dissipation in a “ballast” load bank
  • Highly accurate frequency control, even if there are sudden changes to the user network load
  • Power stage made up of amply dimensioned thyristors
  • Standard design, which facilitates the supply of replacement parts

Electronic level control

This control system adjusts the quantity of water consumed by the turbine depending on the quantity of water actually present in the river, by measuring the water level at the water inlet. In order to achieve this, the system activates the turbine vane openings.

Main characteristics

  • PID regulation algorithm, whose parameters are adjusted according to the hydraulic inertia of the inlet channel / water reservoir
  • Easily-adjustable settings and control parameters
  • Control of hydraulic or electric actuators
  • Optimised efficiency by intelligent turbine gate opening for PLC-controlled systems
  • Standard design, which facilitates the supply of replacement parts
