New energy calculator in HPP-Design

A new HPP-Design feature is online: the Energy Calculator.

What can you do now?

It will be possible to calculate directly on line the production of an HPP.

We have reversed the concept of calculation: usually the flow of information, starting from a very thorough hydrogeological study, provides the calculation of a duration curve. Knowing the geodetic head and after some technical and economic considerations, we can define the turbine’s project data.

With HPP-Design, on the other hand, you can do the opposite: from the project data of the turbine, such as discharge and head, the tool will automatically set a hypothetical duration curve (you can choose between two pre-set curves) and then will calculate energy production if the hydroelectric plant has the chosen duration curve.

Simplifications introduced are:
  • Number of input points. We decided to use only 12 points identified as monthly averages;
  • Turbine efficiency is included (even with the flow variation), but not the generator’s and the transformer’s. At this stage efficiency of the generator and the transformer are equal to 1;
  • The head is constant.

You can also change the default values to define the flow duration curve fitting your HPP.

HPP-Design continues to implement new functions. Our goal is the study and development of new deployment to help designers and developers.
