提高电网输送能力的技术措施

为了满足大容量、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.文章概要介绍了通过现场试验等方法对电力系统动态特性和负荷模型进行研究,采取在关键发电机上安装稳定控制器（PSS）,应用同杆并架和紧凑型输电技术,采用大截面导线和耐热导线技术,采用静止无功补偿装置（SVC）、固定串补（FSC）、可控串补（TCSC）、静止无功发生器（STATCOM）和静态同步串联补偿器（SSSC）柔性交流输电（FACTS）技术等技术措施来提高我国电网输送能力的应用和研究情况,并对第一项由我国自主开发的甘肃TCSC工程进行了重点介绍.

Technical Measures for Improving Transmission Ability of Power Network

To satisfy the demand of high capacity and long distance power transmission and power load increasing rapidly, it is necessary to adopt some technical measures for improving transmission ability of power network. Through the methods of field testing and research for power system dynamic property and load model, the paper summarized and introduced the research condition and application of the technical measures for improving transmission ability of power network in China, such as power system stability controller (PSS), double line on the same tower and compact power transmission technology, large section wire and heat-resisting wire technology, and FACTS technologies of SVC, FSC, TCSC, SVG, SSSC. The Gansu TCSC project, the first autonomous development by China, is also introduced emphatically.
