Governor system for hydropower plant

We provide single-regulation governor (Francis type, Kaplan type), dual-regulation governor (Kaplan type with movable blade, Bulb tubular type), Pelton type special governor. For different hydropower station, we can provide different pressure levels of governors: 4MPa, 6.3MPa, 16MPa, etc. The electrical and hydraulic systems of the governor can be integrated or separated.

Single-regulation governor

Microcomputer-based governor with high oil pressure is a governor that adopts imported industrial controller PLC as the control core, digital valve, or servo proportional valve as electro-hydraulic transducer link, and mechanical hydraulic system as the actuator. This kind of governors is suitable for middle and small hydroelectric generating unit.


Main characters

  • Incorporation of oil pressure device and the governor

  • Energy is stored by bladder accumulator so that the air-compressor system is eliminated.

  • High integrated hydraulic system

  • Digital valve or proportional valve are available for electro-hydraulic transducer.

  • It adopts integrated structure design, and eliminates intermediate components such as pilot distributing valve, main distributing valve.

  • Satisfactory dirt proofing and no oil consumption at static state.

  • No drift at zero position, and convenient for installation and debugging.

  • Flexible layout for the servomotor, and the speed-regulating shaft can be abolished.

  • No disturbance of load when power off.

  • Oil filter with two channels

  • Oil pressure: 16Mpa

  • Governor capacity: 1000N.m, 1800N.m, 3000N.m, 5000N.m, 7500N.m , 10000N.m, 18000N.m, 30000N.m, 50000N.m, 75000 N.m, 100000 N.m.

Dual-regulation governor

Pelton turbine governor

Microcomputer-based governor for Pelton turbine is a self-developed specialized governor based on abundant experiences concerning large and middle governors and on the characters of Pelton turbines. It is suitable for the regulation and control for Pelton turbine/generator units.

Electrical control system

  • The microcomputer-based adopt imported PLC or PCC (optional: duplicating PLC or PCC).

  • Direct digital control.

  • PT frequency measurement and toothed disc frequency measurement are adopted , which are host/standby for each other

  • The startup needles can be freely combined; when the unit operates in the grid, automatically put on/off needles according to the units’ active power. Needles will be synchronized automatically.

  • The needles and deflectors adopt digital coordination.

  • Absolute encoder, linear displacement sensor and potentiometer etc. can be used for electrical feedback.

  • Friendly human-machine interface.
