The Electronic Governor

Hydroelectric power station control room with Fuzz-9800 electronic governor panels installed in the control desks

The Fuzz-9800 is a digital electronic governor built specifically for hydro turbines. It holds speed, load and water level steady in every operating condition, whether your unit runs on its own or on the grid, and takes it from standstill to synchronised and fully loaded at the press of a single button.

Built for hydro, not adapted
Unlike PLC-based governors that adapt general-purpose hardware, the Fuzz-9800 is designed from its electronics to its control algorithms for governing hydro turbines.
Every turbine type
Kaplan (single and double regulated), Francis, Pelton (single and twin jet) and Turgo, configured in software to suit your turbine, actuators and control needs.
Synchronising built in
The auto-synchroniser is part of the governor, so your unit reaches the grid in the shortest possible time. One START button runs the whole start-up, synchronising and loading sequence.
Precise control in every mode
Speed, load and water-level control for isolated and grid-connected operation, tuned to the dynamics of your plant.
Stand-alone reliability
A complete operator interface on the governor itself means it never depends on a PC or other system to take commands or show status.
Proven and standards-based
Fully developed in India and proven in more than 500 installations. Designed to comply with IEC 60308, IEC 61508 and IEEE 125.

Solutions and Services

Support for the whole life of your plant, from the first start-up to decades of reliable operation.

Governor Retrofit and Modernisation
Replace ageing mechanical, analog or obsolete digital governors of any make with the Fuzz-9800. We reuse your existing hydraulics wherever possible to keep cost and downtime low.
Synchronising and Unit Control
Automatic synchronising and start-up sequencing built into the governor. Fewer devices to buy and wire, faster connection to the grid and consistent starts every time.
Commissioning
Our engineers install, commission and tune your governor on site, and hand over a fully tested system ready for reliable operation.
Testing, Monitoring and AI-Based Tuning
Our dedicated testing and monitoring system checks governor performance, predicts faults before they cause a trip, and uses AI to tune the control settings to your turbine.
Annual Maintenance Contracts and Spares
Planned maintenance under an annual contract keeps your plant running, backed by genuine spares for AIMS governors.
Training
Practical training for your operators and maintenance staff, so your team can run and look after the plant with confidence.
