Andhi Khola Power Plant

• Very low efficiency of the power plant
• Little maintenance
• Wrong maintenance

13
Jhimruk Power Plant

• Heavy sand erosion every year
• 6900 tons of sediment load through one turbine
  during the monsoon 2003
• Not operated efficiently

Kali Gandaki Power Plant

• Large problems due to sand erosion of the
  turbines
• NEA not fully understand the problem

Cooperation between Kathmandu University and NTNU
in mechanical engineering

• NTNU-staff teach at KU
• NTNU-staff helps to develop master courses
• Education of KU-staff
• PhD-students
• Bhola Thapa 2001-2004
• Hari Neophane 2007-2010
• Master-students
• Hari Neophane 2002
• Raju Shrestha 2004
• Biraj Singh Thapa 2005

19
Future plans for cooperation

• NTNU and KU apply to NORAD for the development of
  a turbine laboratory at KU.
• In order to do research in Nepal on hydro
  turbines, a turbine laboratory should be
  established

20
The purpose of the Turbine Laboratory

• Build competence and knowledge within the
  waterpower sector in Nepal
• Teaching/learning facility for KU
• Industrial courses
• Staff training for the industry
• Build a test laboratory for mini- and
  micro-turbines
• Certification of mini- and micro-turbines sold on
  the Nepali market
• Product development (pumps and turbines)
• Private testing from local manufacturer
• Motivation for research
• Sand erosion research in turbines
• Turbine and pump technology
• Maintenance of turbines
• Meeting place for the industry and university
• Student projects for the industry
• Research projects will be initiated

21
Research

• Sand erosion on turbine materials
• Sand erosion in turbines
• Turbine development
• Maintenance of turbines
• Efficiency measurements on turbines

22
Student laboratory

• The following laboratory work can be included in
  the theoretical courses
• Pressure measurements
• Velocity measurements
• Flow rate measurements
• Measurement of the friction loss in pipes
• Pump and turbine efficiency measurements
• Various student test rigs

23
Sustainability

• Bhola Thapa is the dean of School of Engineering.
  He has learned much from Norway about how a
  turbine laboratory can work in the future
• Three staff-members from mechanical engineering
  have been to NTNU and learned how to operate a
  turbine laboratory. SINTEF Energy Research has
  given these students scholarship.
• Student work will go on every semester
• Research cooperation can be established with
  companies such as
• Nepal Hydro Electric Pvt. Ltd. (NHE)
• Butwal Power Company Ltd. (BPC)
• Himal Power Limited (HPL)
• Nepal Electricity Authority (NEA)
• Hydro Lab Pvt. Ltd.
• NTNU and SINTEF
