随着我国综合国力的不断加强,我国电网系统运行电压的等级也越来越高,规模也在不断扩大。南方电网作为我国6个跨省的大型区域电网之一,也在不断地改善其内部结构,加快超高压电网的建设力度,制定智能化电网发展策略。文章从南方电网500kV超高压电网实施智能化的必要性、智能电网运用的技术、国外对智能电网体系的建设、中国特色的智能电力体系建设等方面进行了探讨。 With the continuous strengthening of China’s overall national strength, China’s power grid system operating voltage levels are also getting higher and higher, the scale is also expanding. As one of the six large-scale regional power grids in China, China Southern Power Grid is also constantly improving its internal structure, accelerating the construction of EHV power grids and formulating a smart grid development strategy. The article discusses the necessity of implementing intelligent technology for 500kV EHV power grid in China Southern Power Grid, the technology used in smart grid, the construction of smart grid system in foreign countries and the construction of smart power system with Chinese characteristics.
