摘要
世界范围内,电网正处于由第二代电网向第三代电网发展的起步阶段,未来电网的各种概念设计和技术路线研究方兴未艾.总结三代电网的发展历史,归纳其特点;综合考虑能源发展、环境保护、市场需求等外部因素的变化,结合当前电网技术的研究热点和发展潮流,推测电网发展的总体趋势,提炼出可能导致未来电网形态发生革命性变化的3项关键技术:分布式发电技术、大规模储能技术和超导电力技术,论述未来电网设备的功能框架并分析在关键技术突破情况下的未来电网设备形态.
Electric power system is in the early stage, which is developed from the second genera- tion to the third generation, and the conception design and technical research of future power sys- tem are developing. This paper summarizes the history of power system and concludes the three generation features. The changes of external （actors are considered, such as, energy develop- ment, environmental protection, and market requirements. It is necessary to estimate power sys- tem development trend, which is based on the hot spot of current power system technology. Three key technologies （distributed power generation technology, large scale energy storage technology and superconducting power technology） are extracted, they may cause the revolution- ary change of power system. The future grid equipment function framework is discussed and the new grid equipment form is analyzed with the key technologies obtaining a breakthrough.
