PLC programming for hydropower plants

Develop control software that clearly brings together the generating equipment, waterway, grid systems and operator interface.

What good PLC software delivers

  • Clear operating modesClearly distinguish manual, automatic, standstill and fault conditions.
  • Clean interfacesConnect sensors, drives, HMI and higher-level systems transparently.
  • DocumentationDescribe programs, inputs and outputs, and alarms in a maintainable form.

From signal to operating logic

A PLC system must fit the actual plant: turbine, hydraulics, trash-rack cleaner, gate and grid interface each have different requirements.

We organize the software into understandable functional groups and verify it during commissioning together with the real field devices.

Practical implementation

Maintainable control logic

From the I/O list and operating modes to the HMI screens, the programming remains transparent and plant-specific.

  • Planning: Specify signals, actuators and protective functions.
  • Programming: Implement sequences and interfaces in modular form.
  • Commissioning: Verify field signals, alarms and operating modes.
