摘　　要：为满足大容量、长距离输电和电力负荷快速增长的需求,采取一些技术措施提高电网的输送能力十分必要。介绍了提高电网输送能力的方法,提出了限制短路电流的方法—串联电抗法。该方法可提高系统的稳定性和电网输送能力,并通过理论和实例证明了方法的有效性。It is important to enhance transmission capability of power grid by technical measures to meet the needs of large capacity, long dislance and fast increase of power load. This paper introduces the method to enhance transmission capability of power grid, and put forward a method to limit short-circuit current---series reactance method. This method could enhance system stability and transmission capability of power grid. Further it proves the effectiveness of that method by theory and practice.
