电力系统过电压行波传播特性分析

The Analysis of Over-Voltage Travelling Wave Propagation Characteristics in Power systems

电力系统过电压经常会引起输电设备损坏、导致供电中断等事故,过电压在输电线路中以行波的方式传播。详细分析了过电压产生的原因以及过电压行波在输电线路中的传播特性,研究了行波传播的影响因素等,对过电压的测量和判断以及进一步采取应对措施具有重要的现实意义,减少输电设备的损坏,提高供电可靠性。

Over-voltage for power system often leads to trans mission equipment damage,causing power supply outage and other accidents. The over-voltage runs in travelling wave in transmission lines. The paper analyzes the causes of over-voltage in detail and the propagation characteristics of the over-voltage travelling wave in the transmission lines and studies the influencing factors of the travelling wave propagation,which is of important immediate significance to measure and judge voltage and to take relevant measures. It can reduce the transmission equipment damge and increase power supply reliability.
