静止同步串联补偿器及其对继电保护影响的研究
|
摘要
静止同步串联补偿器SSSC是FACTS家族的一种新型的串联补偿设备。本文在分析SSSC暂稳态特性的基础上,系统地将其与可控串联补偿器TCSC作对比以突显其优越性。随后对SSSC应用于电网后对超高压线路上经常配置的几种主保护带来的一系列影响进行了分析,并提出一些改造措施及解决方案。SSSC等FACTS元件的应用对传统保护带来了挑战,本文根据近年来热门的暂态量保护原理,将小波理论、奇异值理论及信息熵理论结合提出一种适合于串补线路的保护新方案-即基于小波奇异熵的单端暂态量保护,仿真研究表明其能有效区分区内外故障,且适用于带串补的超高压线路,效果良好。
The Static Synchronous Series Compensator-SSSC is a new series compensator component of FACTS family. In order to highlight its superiority this paper compares the SSSC to the TCSC based on the study on their steady and transient performance. Then effect of SSSC on the main Protection of Extra High Voltage Transmission line is studied, and some solution methods are proposed. The FACTS components such as SSSC etc have challenged the traditional protection theory. This paper proposes a new scheme for series compensated UHV transmission line which combines the Wavelet theory, Singular value theory and information entropy theory according to the Transient-based Protection theory. That is Single-end Transient-based Protection based on the Wavelet Singular Entropy theory. And the simulation shows that it can efficiently distinguish the fault in or out area,and it adapts to the series compensated UHV transmission line.
