Excitation systems

Main types
  • thyristor self-excitation systems (СТС);
  • independent thyristor systems (СТН);
  • power converters;
  • excitation control systems;
  • excitation system protection.

Advantages of our excitation system design:

  • Maximum safety of operating personnel and equipment is ensured by a set of special measures, including optic cables and draw-out thyristor converters (upon customer’s request).
  • Easy maintenance of excitation boards is achieved through a combination of modular configuration, which ensures easy access to any board component, and the practical layout of controls, alarms, instruments and measurement points.
  • The diversity of designs with regard to customer’s needs allows for the easy transformation of typical sections. Water, forced-air or natural-air cooling of thyristor converters.
  • High degree of operational compatibility is ensured thanks to the location of all electrical connections between sections inside the panel.
  • Proven quality. Excitation systems are tested using equipment from the world’s best manufacturers.
  • Improved design of panels in accordance with European Ergonomic Standards is achieved through the use of state-of-the-art design materials.
Auxiliary equipment
  • various types of hydraulic turbines;
  • hydrogenerators;
  • pre-turbine gate valves;
  • the hydraulic part of governors and oil pressure units;
  • automated control systems of hydraulic turbines.
