Choose HydroSim XP

In the HydroExpert’s “Study Navigator” click on “HydroSim > HydroSim XP” model category.

Use the Study menu

Choose the "Study > New..." menu command. You will see a "New Study" created with the 98 MW “UHE Jurumirim" hydroplant on it.

Time Horizon

With the "Simulation horizon" controls, choose a time horizon to your study.

For example, change the number of days to 7 (one week).

Change the time interval from 30 minutes to one hour using the “Config” tab into "Simulation horizon“ panel.

Determine the OperationDetermine the Operation

Operation & Decision

Select the "Policy" tab. Fill out the "Outflow" (in m³/s) column as an decision policy for this reservoir. For example, you can fill out 300 m³/s.

Hint: fill out one cell, right click on it and choose “Replicate Cells” to fill the entire column.

You can decide Hydro Generation and unit commitment (columns “H. Gen.” and “*”).

Reservoir’s Inflow

Select the "Inflow" tab. Fill out the "Incremental inflow grid" (in m³/s) for the "Jurumirim" reservoir. For example, you can fill out 50 m³/s. This example will simulate a operational scenario with high outflows compared to the inflows.

Hint: fill out one cell, right click on it and choose “Replicate Cells” to fill the entire column.

Select the "Advanced" tab. Setup some "Initial volume" for the "Jurumirim" reservoir. For example, setup at 80% of usage.

Note: the “Limit volume” permits setup a security level as a constraint to the reservoir operation.

Simulated TrajectoriesSimulated Trajectories

Results Tab

First, let’s see the flow trajectories.

We can note that the 300 m³/s trajectory is equal to the Turbine Discharge. In other words, no spill will be present in this operation.

The discharge/outflow trajectory also satisfy the minimum outflow and maximum discharge limits.

The Storage Impact

With the outflow equals to 300 m³/s and with inflow equals to 50 m³/s, it is expected that the reservoir gets empty.

You can change the volume (vertical) axis to:

• Water level (m);• Absolute volume

(hm³, cubic hectometer);

• Volume usage (%).

Advanced Simulation ResultsAdvanced Simulation Results

Turbine Efficiency

The HydroSim XP can calculate Turbine Efficiency using the associated Hill Curve.

The Efficiency Hill Curve is stored in HydroData database and is automatically imported at the study creation step.

At HydroData frame you can find the “Paranapanema > Jurumirim” plant. See “Powerhouse > Units > Hill Curve” tabs.

Hydro Generation

We can see the hydroelectric generation associated with the turbine release of 300 m³/s.

The generation trajectory is continuously decreasing due to the decreasing levels from the reservoir storage.

Also, we can see that the simulation model dispatches an 2-unit commitment to maximize the outflow.
