What we have learnt
- The power system consists of interconnected stages including generation, transmission, and distribution.
- Smart Grid technologies significantly enhance the efficiency and reliability of electricity delivery.
- Power generation practices vary between thermal, hydroelectric, nuclear, and renewable sources, each with distinct operational principles and environmental impacts.
Key Concepts
- -- Smart Grid
- A modernized electrical grid that uses digital communication technology to detect and react to local changes in usage.
- -- Transmission Losses
- Power losses that occur in transmission lines primarily due to resistance, characterized by the formula P_loss = I^2R, where I is the current and R is the resistance.
- -- Power Flow
- The movement of real power (active power) and reactive power through the power system, essential for system stability.
- -- Voltage Control
- The process of maintaining the voltage within specified limits throughout the power system, crucial for reliable operation.
- -- Relay
- A device that detects faults in the system and initiates the necessary protective actions, crucial for maintaining power system integrity.
