doi:10.3969/j.issn.1000-7229.2015.08.012

摘要/Abstract

摘要：

首先介绍了统一潮流控制器（unified power flow controller，UPFC）在国内外理论研究和工程应用的发展和现状。接着具体阐述了南京西环网在发展中存在的输电通道能力不足、潮流分布不均等问题。通过与常规解决措施的对比，阐明了在南京西环网中应用UPFC提高电网输电能力及稳定性的可行性、必要性和必然性。经分析计算发现,通过应用UPFC，不仅能够有效控制电网潮流，提高现有电网的输电能力，从而避免投资巨大、实施难度极大的城市电缆输电通道建设，而且还能够很好地适应未来电网网架的变化。因此，在南京西环网甚至将来的江苏电网中，应用UPFC可以显著提高电网的输电能力、利用效率及运行安全性，能够取得良好的经济效益和社会效益。

Abstract:

Firstly, the development and present situation of theoretical study and engineering application of the unified power flow controller （UPFC） at home and abroad were introduced. Then, the constraints in developing Nanjing Western grid were described in detail, such as limited transfer capacities of power imported channels, unbalanced power flow distributions and so on. Through the comparison with other convention solutions, the feasibility, necessity and inevitability of UPFC applied in Nanjing Western grid to improve the systems reliability and transfer capacity were investigated. Through the analysis and calculation, it is found that the application of UPFC not only can effectively control power flow, enhance the transfer capacity of the existing power grid, which can avoid constructing city-crossed cable channel with huge investment and difficult construction； but also can be well adapted to the changes of power grid frame in the future. Therefore, the application of UPFC in Nanjing Western grid or even Jiangsu grid in the future can prominently improve the transfer capacity, utilization efficiency and running security of power grid, which can achieve good economic and social benefits.

Key words: unified power flow controller （UPFC）, Nanjing Western power system, transfer capacity, operation reliability
