INTRODUCTIONPanauti Hydropower Project is the third hydropower

project of Nepal.Located in Roshi river, Khopasi(Kavre), 35 km east of

Kathmandu.Commissioned during 1960-1965 by the joint effort of

USSR and Nepal government.An installed capacity of 2.4 MW.

OBJECTIVEStudy and prepare the 3-D model for the powerhouse and

switchyard of Panauti Hydropower Project.

Sub-objectives: To study the placement of general equipments inside.To know the surveying techniques, fieldwork, etc.

METHODOLOGY

Primary Data collection (measurements,

observations , etc.)

Start

Desk study Field study

Secondary Data collection (surfing

internet, library visit)

Model Preparation

Final report

PRIMARY DATAPowerhouse

Length=2475cm.

Breadth=1840cm.

Height=709cm.

SwitchyardLength=2740cm.

Breadth=1140cm.

Height of fence=244cm.

Height difference between powerhouse and switchyard=975cm.

Scale:The scale is reduced in the ratio 1:55 to include

powerhouse and switchyard in the plywood of 1*1 m

which further includes automatically staff house.

RESOURCES USED• Instruments: Measuring Tape• Software: AutoCAD

Materials:

- Plywood - Net

- Thermo coal - Hammer

- Fevicol - Chisel

- Paint - Rip saw

- Buttons - Aluminium plate

- Wires - Aluminium and wire cutter

- Knife

STEPS USED TO PREPARE 3-D MODEL -wood works by rip saw and chisels

- cutting the thermo coal by knife -representing the wire by house wire -representing insulators by buttons -potential transformer and oil circuit breaker

by aluminium plate -fence of switchyard by net -towers by net and wood - transformers, turbines and generators by

thermo coal

DIFFICULTIES ON FIELDWORKCrossing the fence of switchyard was prohibited.Restriction of close observation of equipments and

machinery of the powerhouse.Cost overrun compared to forecasted.

RESULTSSurvey and Measurement of power house and switchyard2-D model of powerhouse and switchyard in AutoCAD3-D model (scale 1:55) with topography and details like

transformer, oil circuit breaker, isolator etc of switchyard and powerhouse.

BENEFITSWe learned the measuring techniques.Able to develop teamwork spirit and communication

skills.Learn the technique to make a 3-D modelKnowledge of proper execution and presentationKnowledge about some of the equipments inside

powerhouse and switchyard.

CONCLUSION:

We came to know about the team work. We prepared 2-dimensional model(Top view) of our project site. We got the theoretical and practical knowledge from this project.

Thank You!
