Correct Answer - Option 2 : Central stations with capacity of 10-50 MW
Diesel power plant:
- A generating station in which diesel engine is used as the prime mover for the generation of electrical energy is known as diesel power station.
- The diesel engine drives alternator which converts mechanical energy into electrical energy.
- Diesel power plants produce power in the range of 2 to 50 MW.
- They are used as standby sets for continuity of supply such as hospitals, telephone exchanges, radio station, cinema theatres and industries (peak load).
- They are suitable for mobile power generation and widely used in railways and ships.
Conclusion:
Diesel power plant can work as peak load plant, mobile plants and as standby units.
Diesel power plant not work as central stations with capacity of 10-50 MW, so this statement is wrong. Therefore Option 2 is the correct answer.
