HVDC transmission system is basically environment-friendly because improved energy transmission possibilities contribute to a more efficient utilization of existing power plants. The ever increasing demand of electricity has laid enormous pressures on the present infrastructure of the power generation capacity. HVDC systems can transmit more electrical power over longer distances than a similar alternating current (AC) transmission system, which means fewer transmission lines are needed, saving both money and land. Beside power generation, transmission loss is also of the main worries as huge transmission losses are being incurred by the present AC transmission. Hence, HVDC transmission becomes an interesting preposition across the globe due to its lower transmission losses, asynchronous interconnection and the capability to deliver bulk power for long distance transmission.
The HVDC market is growing rapidly and has become an important part of many transmission grids. HVDC transmission systems form an integral part of the electrical power system to improve the overall stability and reliability. Further advancement in converter technologies such as power semiconductors has added new dimension in HVDC transmission, which encapsulates underground, offshore and voltage-stabilization applications. These applications have pushed further demand for the HVDC transmission.
HVDC transmission systems offer the best technical and economical long distance transmission solutions, integrating renewable generation, and stabilizing power networks. With its inherent technical properties and superior ability of control, HVDC transmission is a key component in the future energy system based on renewable energy sources. HVDC transmission is used for connecting offshore wind farms which are often placed far out at sea, because the wind conditions are more advantageous at such locations. If the distance to the grid on land exceeds a certain stretch, the only possible solution is use of HVDC - due to the technology’s low losses. HVDC has the ability to carry high voltage power over long distances with low transmission loss. It is believed that wind application will be dominant factor that will impact the HVDC transmission market the most.
