| 摘 要： | 针对末端接负载的高压交流线路,提出了一种有限长线路的无线电干扰计算方法,将激发函数法与贝瑞隆法相结合,得出电晕电流经过折反射后的电流元分布,再对电流元产生的场强进行叠加得到无线电干扰,以变电站附近线路为例,比较了有限长与无限长导线的电晕电流分布特性,得出末端阻抗、起晕点位置均是影响有限长线路无线电干扰水平的重要因素。

| Abstract: | For HVAC transmission line with load connected to its terminal,a method to calculate radio interference caused by finite-length of transmission line is proposed.Integrating Bergeron method with excitation function method,the distribution of current element after the reflection and refraction of corona current is obtained,and then the field strengths producing by current elements are superposed to solve radio interference.Taking the transmission line near substation for example,the distribution characteristi... |
