Control and automation

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

Electronic speed control with turbines valves command

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

  • Frequency control 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 valve 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 regulate the speed of the turbogenerator group by controlling the electric charge applied to the alternator. It finds its application in :

  • Frequency regulation of turbine generator units not connected to the national grid
  • The coupling of turbine generator units to the national grid.

Main characteristics :

  • PID control algorithm whose parameters are adjusted according to the inertia of the turbogenerator group
  • Regulation by dissipation of energy in a bank of “ballast” electrical charges
  • Very precise control of the frequency, even in case of sudden variation of the load of the user network
  • Power stage composed of large sized thyristors
  • Standardized design, facilitating the supply of spare components

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 valve 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
