According to the grid’s 11th Five-Year Plan, the ultra-high voltage transmission will take its place in the power grid soon.展开更多

Facing the target of reducing SO2 emissions by 10% in the 11th Five-Year Plan period, it is important for both the desulphurization industry and electric power industry to sum up the experience and think of the future.展开更多
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.
To improve the operation reliability of power supply system in China, it is of great significance to know the status of condition-based maintenance (CBM) in the system and accumulate related experience in recent years...To improve the operation reliability of power supply system in China, it is of great significance to know the status of condition-based maintenance (CBM) in the system and accumulate related experience in recent years. This paper analyzes the current modes of detection and repair, maintenance periods, the operation status of on-line monitoring devices equipped and the existing problems of them. The results show that there exists an urgent need in intensifying the quality control and inspection of on-line monitoring products at present.展开更多
