HYDROLOGY of HYDRO-POWER PLANTS

HYDROLOGY of HYDRO-POWER PLANTS

The discharge data of the river is required minimum for 25 years. For estimation of hydro power potential, The discharge data corresponding to these years have been tabulated in table the water available for power

generation has been calculated. 

Dependable Discharge

In figure, the year wise total annual runoff, and determination of 50% dependable year (1975) have been raphically presented. the ninety (90) percent, fifty(50) percent and seventy five(75) percent dependable discharge available for power generation have been determined and are stated below based on discharge data.

WATER AND POWER STUDIES  

P (MW ) =  (9.81  x  Q  x  H x ht  x  g )
Where,
 
  Q = Discharge in cubec
  H = Head in metre
  ht x g =Overall efficiency

DESIGN ENERGY

The design energy is the energy likely to be produced in the 90% dependable year with 95% availability.
