摘要
Today, high-voltage transmission systems in China are well developed and they have come up to the advanced world level in both management and technology. However, there still exists quite a wide gap in the management and technology of distribution system, in particular, medium-voltage distribution system as compared with developed countries. It is imperative to heighten the technical level of distribution system in an all-round way so as to ensure the sustainable development of power network.
Currently, the distribution systems of China, especially those of medium-voltage, are uncoordinated with transmission systems in configuration, and are in urgent need of upgrade.
