3.4 Methods of fixing installed capacity of a hydropower plant
Hydropower project is planned to develop in a river having net head of 100 m and overall efficiency of 85% with the monthly hydrograph as shown below:
| Month | Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Discharge | 100 | 120 | 140 | 300 | 320 | 1800 | 2000 | 2500 | 2100 | 900 | 500 | 300 |
i) Calculate installed capacity, annual spill energy and firm energy if RoR project is designed based on the 40% probability of exceedance flow. ii) If the storage project is developed with full regulation of annual hydrograph (design discharge is equal to average monthly flow), Calculate the storage requirements. iii) Calculate the installed capacity and annual energy generation from the storage project as mentioned in above case.
