Digital Governors

MRT Control Panel

The standard configurable MRT Governor controller is a cost-effective solution offering high performance and versatile control for Francis, Kaplan, or Pelton units.

Applications

  • Designed for Francis, Kaplan, and up to two needle Impulse turbines.
  • Retrofits of existing mechanical, analog, and early digital
    governor systems.
  • Complete governor system replacements.

Advantages

  • Standard product means fast delivery and competitive price
  • Versatile design reduces installation time and fast commissioning
  • Off-the-shelf components ensure availability and cost-effective spare parts
  • Powerful control algorithms offer fast system response
  • Modular design allows customization to meet any need.

High-performance and versatile control

  • Meets international speed governor standards IEEE-125 & IEC-308
  • Speed, position, power, flow, and level control
  • PID parameter sets for Isolated, off-line, and on-line control
  • Optimized Kaplan turbine efficiency with 3D CAM for blade control.
  • Configurable predefined position of Kaplan blades or Pelton deflectors for start-up breakaway and over-speed shutdown conditions
  • Synchronous condense, brake, and creep control
  • Auto-Manual, Local-Remote operation
  • Automatic synchronization capability
  • User Configurable to easily integrate into existing controls, or to meet future requirements
  • Designed to replace existing mechanical, analog, or early digital system without requiring changes to existing unit control or plant control systems
