MICROHYDRO eGroup


This page gives an overview of topics discussed in the microhydro eGroup and serves as a location of putting documents or graphics interested to the group, but too large to send as attachment to groupmembers directly 
Anyone interested in having his/her documents placed here, please contact me at klunne@itc.nl.
More information on this discussiongroup can be found here.

Penstock losses
In reaction to a question posted by Ola Tambour on how to calculate penstock losses, Joseph Hartvigsen posted two MathCad worksheet with examples calculating losses in pipe flow.

Steve Opelc reacted to Ola's question by sending a micro-hydro software program that might be useful for this. It is a DOS program, fairly old but works under windows 95. More information can be found in the file pc-hydro.doc. The program works with cells as in a spreadsheet, in order to move between the cells you have to use the arrow keys on your keypad (it will not work with enter, or your normal arrow keys).

Turbine images
Joseph Hartvigsen provided me with some pictures of turbines which he though to be of interest to the group. You can find them here.

Joseph Hartvigsen made two turgo runners for members of the microhydro-egroup. They are about 9 cm pitch diameter and can use jets up to about 13 mm in diameter. See the picture below (click on it for an enlargement).

For those who want to build a system themselves, Joseph put together a small "catalogue" of components he can supply. As he does not have a web-site himself, I provide this catalogue here (in pdf format).
JLA software
Group member Jean-Luc Willot from Belgium developed a computer programme which might be of great help to a lot of us. 
His JLA program can be used to:
  • evaluate the flow discharge at a measurement weir using the overflow method
  • slope calculations for a trapezoidal channel
  • diameter calculations for a penstock
  • sizing of transmission cables
  • together with the selection of the optimal turbine from the JLA turbine series.

    It is a DOS programme and you can find it in zipped format here.
    (Interested persons might also have a look at the JLA company profile.)
    Electronic Load Controller
    Jan Portegijs designed the Humming Bird Electronic Load controller. More information, including the full manual can be found here.

    Jan Portegijs also developed the 'Swingcat Tidal Turbine’ concept. Although not micro in its scale, the manual of the Swingcat is available at this site: swingcat.zip.
    Microhydro manual in Spanish
    Some time ago I found a very interesting pdf-file on the internet of a full manaul in Spanish on how to develop a microhydro scheme. Unfortunately I cannot trace were I found the file, so I do not have a reference. However, I downloaded the pdf-file and made it available on the Internet. As it is a very large file (13 MB in total) that would not fit within my available diskspace, I split the document in two part. Part one (approx. 8 MB, pages 1 to 148) can be downloaded here, the second part (approx 5 MB)  by following this link. If any of you know more about the source of this document, please inform me.
