A generating station has a maximum demand of 20 mW, load factor of 60%, a plant capacity factor of 50% and a plant use factor of 72%. What is the reserve capacity of the plant, if the plant, while running as per schedule, were fully loaded?
-
- 10 MW
- 15 MW
- 2 MW
- 5 MW
Correct Option: D
| Load factor = | ||
| Maximum demand |
| or 0.60 = | ||
| 25 |
∴ Average demand = 25 × 0.60 = 15 MW
| Plant capacity factor = | ||
| Installed capacity |
| or 0.50 = | ||
| Installed capacity |
| ∴ Installed capacity = | = 30 MW | |
| 0.50 |
Reserve capacity of the plant = Installed capacity – Maximum demand = (30 – 25) = 5 MW
