WCKDE

It is designed for the calculation of transient processes in HPP and PSPP units with Kaplan and Deriaz turbines and pump-turbines of double-acting.

The computer model includes an automatic control system and an isolated power system.

Capabilities:

  • Kaplan and Deriaz turbines and pump-turbines of double-action;
  • Turbine and pump modes of operation;
  • Regulation according to the law of changing the opening of the wicket gate and changing the angle of the blades or the turbine governor by gate-blade relationships dependence;
  • Transient processes:
    • put in operation;
    • load changing;
    • discharge changing;
    • pull up the unit;
    • load rejection;
    • impute failure;
    • frequency control in isolated power system.
