【摘要】 本文介绍了以EMTP为计算工具,对天生桥—广州500kV输电系统的内部过电压进行研究的结果。针对建网初期单机容量小、输电距离长的特点,提出了一些限制过电压的措施。本文还将部分计算结果与TNA模拟的结果进行了比较。EMTP程序经扩充以后,已可用于工程计算.更多还原

【Abstract】 This paper presents the results of study on the internal over voltages of Tianshengqiao-Guangzhou 500kV power system by means of EMTP, According to the nature of the primary stage of system foundation that, the power of generation unit is small and the transmission distance is large, the measures limiting over voltages are represented.The part of the results obtained with EMTP is compared with that simulated with TNA.The EMTP intensified by us has been used to compute engineering.更多还原
