Dynamic Physical Model of 1 000 kV UHV AC Transmission System

在论证中国有重点地建设特高压输电系统动态模拟试验系统的必要性后,介绍了特高压输电线路、变压器系统、并联电抗器等模型的建设情况,针对特高压的特殊性对其输电线路及特殊的变压器组开展了动模试验,研究了特高压带来的新问题和物理现象。实验证明该模型的试验结果与对原型的基本理论分析相似,可用于研究特高压系统的暂态特性和相应的二次设备性能。

This paper discusses the necessity of establishing the dynamic physical model system of UHV AC transmission system, and introduces the construction of UHV transmission lines, transformers, shunt reactors, and so on. A lot of dynamic simulation experiments are done on transmission lines and transformers with special features on UHV. The unique problems and phenomena arisen in the UHV system are studied. The experiments show that the result of the physical model is identical with the theoretical analysis on the prototype, and the physical model can be used to study the transient characteristics on UHV system and the characteristics of secondary devices.
