Designed for the calculation of operational and emergency transient processes at PSPPs and HPPs with individual and branched pressure systems, surge tanks and units with Francis turbines and pump-turbines.
Capabilities:
- Francis turbines and pump-turbines;
- Turbine and pump operation;
- Pressure relief valve on each turbine;
- Main and tailwater conduits;
- Up to 10 penstocks;
- Upstream and downstream surge tanks;
- Regulation according to the law of changing the opening of the wicket gate or the turbine governor;
- Transient processes:
- put in operation;
- frequency put in operation and increase flow;
- load changing;
- discharge changing;
- pull up the unit;
- load rejection;
- impute failure;
- transfer from pump mode to synchronous compensator mode;
- transfer from the synchronous compensator mode to the pump mode;
- transfer from turbine mode to synchronous compensator mode;
- transfer from synchronous compensator mode to turbine mode;
- transfer from pump mode to turbine;
- transfer from turbine to pumping mode;
- load rejection followed by load increasing.
