SMALL HYDRO POWER DESIGNER v1.0

Release Jan - 2009

HPD v 1.0 is an excel workbook equipped with useful design tools for feasibility level analyses / design

mall high head hydropower projects (upto 10 MW). However, the user can modify the workbook to inclu

dditional modules suited for larger projects.

HPD can assist in quickly producing layout alternatives, making reasonable cost estimates / cost

omparisons for these alternatives and preparing concrete outline drawings of major structures using

AutoCAD. SHPD is a freeware intended for engineering students as well as practising hydropower

ngineers.

A user interface is also provided for assisstance of new users. The workbook and interface both have be

reated using Excel 2007 Professional Plus (vista) and are ensured to work correctly only for the same

ersion. Please enable macros before entering or editing the inputs and read the "License.txt" file befor

sing SHPD.

ypical layout of small hydro components adopted in SHPD is like this;

Tyrolean weir as intake

Connecting channel from intake to sandtrap

Concrete sandtrap with spilling and flushing controls

Headrace (Channel or Pipe)

Forebay with spilling and flushing controls

Penstock with manifold

Powerhouse (Building Size + Hints on Turbine Selection)

Tailrace Channel

USER INTERFACE

he workbook requires macros to be enabled for full functionality. The user interface has been tested on Excel 2007 only. The

orkbook can be saved as 'office xp' type for earlier version of Excel or you can download 'office compatibility pack' from microsebsite.

you get error messages on startup ofSHPD then enable macros and close the user interface. The major inputs can be direc

ntered into the SUMMARY worksheet. The design worksheets have been hidden for safety against unintentional damage

owever, the password to unhide these sheets is given in this help file.

he first screen introduces the conceptual layout of a small hydropower project;

he very first input required by SHPD is the hydrological data of the river/stream under study.

ext tab opens the main DESIGN dialogue box. All the design and drawing modules are controlled through this dialogue box

xcept for the costing and capacity optimization modules. The user is required to click on the DESIGN button after any

gnificant change in the major inputs.

efinition sketches of major hydraulic structures have been included for quick reference. The concrete outlines of major hydrau

tructures can be drawn automatically using SHPD in combinition with AutoCAD by clicking on the AutoCAD button.

The DETAILED HYDRAULIC DESIGN dialogue box can be accessed through the HYDRAULIC STRUCTURES button

he DESIGN tab. The quantities of various civil works are calculated based on the design and dimensioning performed through

etail design module.

he user should confirm the status ofDESIGN CHECKS after each run ofSHPD. Detailed error reporting has not yet been

corporated in SHPD however, the above mentioned design checks may prove to be very usefull for experienced as well as n

sers.

he costing of civil works can be done in any currency through COSTING tab. The quantities of major civil works like earth wo

oncrete works, stone works and steel quantity for penstock pipe are automatically calculated in SHPD. Only the dollar exchanate is required for the local currency. After each change in this dialogue box the user is required to click on the UPDATE but

he optimization of installed capacity is a necessary task for any feasibility study in the field of hydropower engineering. SHPD

apable of performing this task very very quickly provided the user is familiar with the general design logic ofSHPD. It is requi

o run SHPD various times by varying the design discharge and the outputs from these runs is entered into the OPTIMIZATI

ab where a single click on the UPDATE button will perform the optimization.

he AUTO OPTM. button will start the automatic optimization module which can change the design discharge automatically a

pdate the inputs required in the OPTIMIZATION tab with minimal design checks. The AUTO OPTM. module is under

rogress and the results may not be reliable at all.

he user interface is under development and your relevant feed back will be highly appreciated.
