介绍了柔性交流输电技术（flexible AC transmission system，FACTS）的发展及应用现状，并针对江苏电网在规划发展中存在的问题，以过江中通道、南京西环网、苏州南部电网为例，通过系统仿真分析研究了在江苏电网中应用FACTS技术提高电网输电能力及稳定性的可行性。经研究发现：通过应用FACTS技术，能够有效控制电网潮流，提高现有电网的输电能力，从而避免了投资巨大、实施难度极大的过江通道及城市电缆输电通道的建设，并能够解决特高压直流双极闭锁等严重故障时电网可能出现的电压稳定问题。可见，在江苏电网应用FACTS技术可以显著提高电网的效率及安全性，能够取得良好的经济效益和社会效益。

The current status of the development and application of flexible AC transmission system (FACTS)were introduced.According to the problems in the planning and development of Jiangsu power grid,taking middle across-Yangtze-river transmission channel,western-Nanjing inter-city circle grid and southern-Suzhou system as examples,the feasibility that the application of FACTS could improve the reliability and transfer capacity of Jiangsu power grid was studied and analyzed through system simulation.The results show that:with the application of FACTS,the power flows in the system can be effectively controlled,the transfer capacity can be obviously improved,so as to avoid the huge investment and difficult construction for the new across-river transmission channels and across-city cables,and solve the voltage unstable problem caused by severe faults such as bipolar latched in UHVDC system,etc.In summary,the application of FACTS can prominently improve the efficiency and reliability of Jiangsu power grid,which can achieve good economic and social benefits.
