WKV Governors

Digital/analog speed governor type SRE 2000

This is a complete new development by WKV. This governor is unique in the world of controls as it combines the advantages of both digital and analog controls.

Display of the main control parameters
PID controls with the option of external disturbance correction ensure stability even in case of long penstocks or in case of instable grid
Modular 19” rack design for easy implementation and exchange of components
Protection against external faults, all I/O circuits are protected against external shorts and reverse polarity
Easy adjustment of all main parameters by means of only a screw driver, no programming, no software or terminal, no laptop required
Inductive non-contact speed sensor
Designed for operation with PLC based controls or a remote control system
Suited for speed control, output control, discharge or level control, as well as for double-regulated units (injector/ deflector or guide vanes/runner blades)
Sturdy, user-friendly design and technology
WKV offers a life-long guarantee on the supply of spare parts and services

Hydraulic power units

WKV offers a complete range of hydraulic power units for control applications. This includes simple actuators for operation on a grid (level or discharge control) as well as the most complex applications involving isolated network or parallel operation.

Designed for decades of continuous operation – only the best components will be used
Low-pressure hydraulics for extended service life up to 300 000 operating hours or even more
Energy-saving designs
For most applications there is no need for maintenance-intensive high-pressure accumulators

WKV manufactures the complete range of governors in-house - a benefit to you! Our governors and hydraulic power units are being used worldwide.

WKV level control for parallel operation

Our water level controllers are designed to ensure the best possible use of the available water. Your unit will run most economically!

PLC controlled operation to achieve optimum efficiency for multi-jet impulse turbines as well as for twin-cell Crossflow turbines
Indication of the intake water level
Surge-protected water-level sensors provide safe operation even under adverse environmental conditions
User friendly adjustment of set points

Electronic load controller

Electronic load controllers are designed for smaller units supplying isolated loads as well as for the emergency power supply of grid-connected units. They keep the frequency constant by feeding the surplus energy to a ballast load.

Suitable for a capacity up to 800 kW
Excellent frequency-accuracy even during load acceptance or rejection
Heavy duty industrial grade electronics especially designed for extreme ambient conditions

Mechanical governors and their maintenance

For some applications mechanical governors may provide significant advantages. WKV offers a full line of such governors manufactured in-house:

Series AA1 - AA3 (250 Nm - 750 Nm)
Robust and well-proven technology
Completely without electronics - best suited for applications in remote locations

Maintenance and spare parts of all "JAHNS" governors
