Описание: විදුලි සම්ප්‍රේෂණ පද්ධති
1. Generation
Electricity is generated at power plants using various sources such as coal, natural gas, hydroelectricity, wind, solar, and other renewable resources. In Sri Lanka, the generation mix includes thermal, hydro, and renewable energy sources.
2. Transmission Substations:

The generated electricity is sent to transmission substations. These substations transform the voltage levels to prepare the electricity for efficient long-distance transmission.
3. Transmission Lines:

High-voltage transmission lines carry electricity over long distances from power plants and substations to regional or distribution substations. The transmission lines help minimize energy losses during the transportation of electricity.
4. Voltage Levels:

The transmission system operates at various voltage levels, including high voltage (HV) and extra-high voltage (EHV). High voltage is typically used for regional transmission, while extra-high voltage is employed for long-distance transmission.
5. Grid Interconnection:

The transmission system is part of an interconnected grid that enables the transfer of electricity between different regions and facilitates the balancing of supply and demand. In Sri Lanka, the national grid interconnects various parts of the country.
6. Substations:

Substations play a critical role in the transmission system by transforming voltage levels, providing switching capabilities, and enabling the flow of electricity between different segments of the grid. They also serve as points for monitoring and control.
7. Control and Monitoring:

The transmission system is monitored and controlled in real-time to ensure grid stability and reliability. Advanced technologies and control systems are used to manage the flow of electricity, respond to changes in demand, and maintain the overall health of the grid.
8. Ceylon Electricity Board (CEB):

In Sri Lanka, the Ceylon Electricity Board (CEB) is the state-owned utility responsible for electricity generation, transmission, and distribution. The CEB oversees the operation and maintenance of the electricity transmission system.
9. Interconnection with Distribution:

The transmission system is interconnected with the distribution system, which delivers electricity to end-users, including residential, commercial, and industrial consumers.
10. Future Trends:
Some electricity transmission systems are evolving to accommodate smart grid technologies, which incorporate digital communication and control systems to enhance efficiency, reliability, and sustainability.

For the most accurate and up-to-date information on the electricity transmission system in Sri Lanka, please contact the Ceylon Electricity Board or relevant authorities directly. They can provide details specific to the current infrastructure, projects, and developments in the country's transmission system.

The specifics may vary based on the electricity transmission infrastructure and projects in place at any given time. For the most accurate and up-to-date information, it's recommended to contact the Ceylon Electricity Board (CEB) or the relevant authorities in Sri Lanka. Here is a general overview:

High Voltage (HV):

High voltage transmission lines in Sri Lanka often operate at voltages typically considered as high voltage. High voltage levels can vary, but they are generally in the range of 66 kV (kilovolts) to 220 kV.
Extra-High Voltage (EHV):

For long-distance transmission and interconnecting major regions, extra-high voltage (EHV) levels are used. EHV transmission lines in Sri Lanka may operate at voltages beyond 220 kV. Common EHV levels include 400 kV and above.
It's important to note that the specific voltage levels can depend on the design of the transmission infrastructure and the requirements of the grid. Voltage levels are chosen based on factors such as the distance of transmission, the capacity of the lines, and considerations for minimizing energy losses.

For precise information on transmission voltages in Sri Lanka, including any recent changes or developments, you should reach out to the Ceylon Electricity Board or the relevant authorities. They can provide details about the current voltage levels used in the country's electricity transmission system.
