Combined Operation of Power Plants Interview Questions:

Following are the below Combined Operation of Power Plants Interview Questions and Important Questions which is very useful for interviews and exams

1. State the advantages from operating the hydro and thermal power plants in co-ordination.

2. What advantages accrue from operating a hydro and a thermal plant in co-ordination ?

3. What do you understand by ‘peak load plant’ and ‘base load plant’ ?

4. Which of the following plants are suitable for use as base load plants ?  (i) Run-off river plant (ii) Storage hydro plant (iii) Pumped storage plant (iv) Steam power plant (v) Nuclear power plant.

5. Discuss the conditions with reasonings under which electric power generation by (i) hydro power stations (ii) thermal power stations (iii) diesel power stations and (iv) nuclear power stations become economical. Which of them would you recommend for base load and peak load operations ?

6. What are the advantages of interconnection of power stations ? Two power stations, one thermal station and the other hydro, how they will be connected in parallel ? Which will be used as base load station and which will be used as peak load station ? Justify your answer.

7. Explain base load and peak load stations. In an interconnected hydroelectric and steam stations, which is used as peak load stations and why ? Run-off river plant, nuclear plant, hydro plant with storage, steam plant and hydro plant with limited storage are connected in the system. Show with the help of a diagram how load allocation may be done.

8. What are the general considerations for interconnection and combination of different types of power generating stations.
