Electrical Engineering XYZ MCQs
In an interconnected power system, the most suitable power plant to meet the peak load condition is:
- Nuclear plant
- Thermal plant
- Hydro power plant
- Pumped storage plant
Correct answer: 4. Pumped storage plant
Explanation: The most suitable power plant to meet peak load conditions in an interconnected power system is a Pumped storage plant. Pumped storage plants are specifically designed to handle peak load conditions in interconnected power systems. During periods of low demand or excess generation capacity, they pump water from a lower reservoir to an upper reservoir. When demand increases and there is a need for additional power, water is released from the upper reservoir to the lower reservoir, passing through turbines to generate electricity. This process allows pumped storage plants to respond rapidly to changes in demand and provide additional power during peak load conditions, making them the most suitable option for this purpose in interconnected power systems.
