Definition and purpose of transmission system

Transmission system is a network of electrical equipment used to transmit power from power plants to consumers.

The main purpose of a transmission system is to efficiently transmit electrical power over long distances.

Components of a transmission system

Power plants: where the electricity is generated.

Substations: where the voltage is stepped up or down.

High voltage transmission lines: used to transmit the power over long distances.

Transformers: used to change the voltage levels.

Classification of transmission system

Based on voltage levels: High Voltage (H.T) and Low Voltage (L.T) transmission systems.

Based on operation: AC (Alternating Current) and DC (Direct Current) transmission systems.

Selection of voltage for H.T and L.T lines

Factors influencing the selection of voltage

Load requirements: determines the voltage level needed for efficient power transmission.

Transmission distance: longer distances require higher voltages to minimize power losses.

Cost considerations: the chosen voltage must be economical and feasible for implementation.

Advantages and disadvantages of high voltage transmission

Advantages

Reduced power losses: higher voltage results in lower current, minimizing resistive losses in the transmission lines.

Economic efficiency: lower losses improve overall efficiency and reduce the cost of power transmission.

Increased transmission capacity: higher voltage allows for the transmission of more power over the same infrastructure.

Voltage regulation: high voltage allows for better voltage regulation across the transmission network.

Disadvantages

Increased insulation requirements: high voltage transmission lines require specialized insulation to prevent leakage and electrical breakdown.

Safety concerns: high voltages pose a greater risk to human safety, requiring strict safety measures during installation and maintenance.

Higher initial investment: building and maintaining high voltage transmission infrastructure can be more expensive initially.

Advantage of high voltage for transmission (both AC and DC)

AC transmission advantages

Flexibility: AC systems allow for easy voltage transformation and are suitable for long-distance transmission.

Efficiency: AC systems can achieve high transmission efficiency with the use of transformers.

Compatibility: AC systems are compatible with most generators and loads, making them widely applicable.

DC transmission advantages

Low losses: DC systems have lower transmission losses compared to AC due to absence of reactive power.

Increased control: DC systems allow for better control of power flow and provide stability to interconnected grids.

Long-distance transmission: DC transmission is more suitable for transmitting power over longer distances and underwater cables.

Integration of renewable energy sources: DC systems can efficiently integrate renewable energy sources like solar and wind power.
