3.4 Methods of fixing installed capacity of a hydropower plant
A hydropower project is planned to develop in a Nepalese River having net head of 150 m, turbine efficiency of 90% and generator efficiency of 95% with the monthly hydrograph as shown below:
| Months | Oct | Nov | Dec | Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Q (m³/sec) | 100 | 80 | 60 | 50 | 40 | 30 | 40 | 50 | 70 | 110 | 150 | 120 |
As an environmental flow, a minimum flow of 10% of each month is mandatory. If the storage project is designed with full regulation of annual hydrograph, find out: the capacity of the reservoir; installed capacity of the power plant, and annual energy generation. [3+2+3]
