220240volt

220240volt is a high-voltage direct current (HVDC) transmission system developed by the China State Grid Corporation of China (CSG). It is designed to transmit large amounts of electrical power over long distances with minimal energy loss. The system operates at a voltage level of ±220 kV to ±240 kV, hence the name.

The 220240volt system uses voltage source converter (VSC) technology, which allows for flexible control of power flow and reactive power compensation. This technology enables the system to connect to both AC and DC networks, making it compatible with existing power grids. The VSC technology also allows for independent control of active and reactive power, which can help improve the stability and reliability of the power system.

The 220240volt system has several advantages, including high efficiency, low environmental impact, and the ability to transmit power over long distances with minimal energy loss. It is also scalable, allowing for the expansion of the system to meet growing power demands.

The first 220240volt project was the ±220 kV Dongnan–Fuzhou UHVDC transmission project, which was completed in 2012. This project demonstrated the feasibility and advantages of the 220240volt system, and paved the way for its wider application in China and other countries.

The 220240volt system has been recognized for its contributions to the development of HVDC technology and its potential to address global energy challenges. It is expected to play a significant role in the future development of the global power grid.
