Which of following is an objective of power system:
- Supply energy at rated V/f
- Minimum cost of energy per KWh
- Both of these
- None of the above
Correct answer: 3. Both of these
Explanation:
- Supply energy at rated V/f: This is an important objective of a power system. Voltage (V) and frequency (f) are crucial parameters that need to be maintained within certain limits to ensure the proper functioning of electrical devices and equipment connected to the power system. Deviations from the rated voltage and frequency can lead to malfunctions and damage to equipment.
- Minimum cost of energy per KWh: Another significant objective of a power system is to provide electricity at the lowest possible cost. This involves optimizing the generation, transmission, and distribution of electrical power to minimize expenses and, consequently, reduce the cost per kilowatt-hour (KWh) for the end consumers.
Therefore, both of these objectives are important considerations in the design, operation, and management of a power system.
