Power Systems | Lecture-2 | Review of Fundamental Concepts of Power System

Описание: A Power System refers to the interconnected network of electrical components used to generate, transmit, and distribute electricity. The key components of a power system include:

1. Generation: This is where electricity is produced, typically through power plants. Sources of generation include coal, natural gas, hydro, nuclear, solar, and wind.

2. Transmission: High-voltage transmission lines carry electricity over long distances from power plants to distribution systems. This reduces the loss of electricity during transportation.

3. Distribution: This system delivers electricity from the transmission network to homes, businesses, and industries. It operates at lower voltages than the transmission system.

4. Protection Systems: Devices like circuit breakers, relays, and fuses are used to protect the power system from faults and to ensure the safety of electrical equipment and operators.

5. Load: Refers to the electrical demand or consumption of power by consumers. Load forecasting is crucial to ensure a stable power supply.

6. Voltage Regulation: This ensures that the voltage at the consumer’s end remains within acceptable limits despite fluctuations in load.

7. Power Quality: Refers to the consistency and stability of power supply in terms of voltage, frequency, and waveform, without significant disturbances or interruptions.

8. Control Systems: These manage the operation of the power system, such as the load balance, voltage regulation, and frequency control to ensure a reliable power supply.
