【摘要】：变电站是整个电网体系中的重要部分,随着变电站电压等级的不断提高,变电站数量的不断增加,新技术、新管理方法势必不断的应用到电力系统中。当代的电网体系已进入超高压(远程输送电压达到500KV-1000KV)、长距离(大电能的传输一般跨省或跨几个省)、大容量和高度自动化的时期,传统变电站也逐步向智能化变电站发展。数字化变电站是智能变电站的早期形式,数字化变电站中,电子式互感器是重要的组成部分,其在现场的管理和运行检修分析已经变得越来越重要,也是本文重点关注的内容。本文主要包括以下几个方面:(1)、通过对传统互感器以及电子式互感器理论方面的研究,分析比较了传统互感器和电子式互感器的工作原理、结构构成、实际运行中的优缺点及在实际应用中应该注意的问题。(2)、从电力系统的发展进程分析了电子式互感器投运的必然性及意义。(3)、通过对已投运的上海220千伏泸定变电站中的电子式互感器的运行情况分析,对电子式互感器运行效果进行评估。
[Abstract]:The substation is an important part of the whole grid system. With the continuous improvement of the voltage level of the substation, the number of substations is increasing continuously. The new technology and new management methods are bound to be applied to the power system continuously. The modern grid system has entered the ultra high voltage (500KV-1000KV) and the long distance (large electric energy transmission). The traditional substation is gradually developing to the intelligent substation in the period of high capacity and high automation. The digital substation is an early form of intelligent substation. The electronic transformer is an important part of the digital substation. The analysis of the management and operation and maintenance of the current field has become more and more heavy. This article mainly includes the following aspects: (1) through the research on the theoretical aspects of the traditional transformer and the electronic transformer, this paper compares the working principle of the traditional transformer and the electronic transformer, the structure structure, the advantages and disadvantages of the actual transportation and the problems that should be paid attention to in the practical application. (2) from the development process of the power system, the inevitability and significance of the electronic transformer are analyzed. (3) through the analysis of the operation of the electronic transformer in the Shanghai 220 thousand volt Luding substation, the operation effect of the electronic transformer is evaluated.
