摘要
电网规模的不断扩大使得同塔双回甚至多回架设输电线路成为输电网的发展趋势,感应电压和感应电流是由2条或多条同塔或邻近平行布置的架空输电线路间的静电感应和电磁感应作用所产生,文中给出了同塔双回输电线路感应电压和电流的计算公式,对影响感应电压电流的主要因素进行了分析,介绍了仿真软件ATP-EMTP,EMTPE\EMTS,MATLAB\Simulink在输线路参数计算中的应用,并对220 kV同塔双回线路感应电压和电流进行了计算,指出了各仿真软件的优缺点及其应用范围。
The continuous expansion of power system makes the same tower double-circuit or more-circiut transmission lines becoming the development trend of transmission network. The induced voltage and current is generated by the two or more transmission lines on the same tower or the electrostatic and electromagnetic induction effect of adjacent parallel arrangement of overhead transmission lines. In this paper, the calculation formula for induced voltage and current of double-circuit transmission line is provided. Also, main factors affecting induction voltage and current are analyzed. The applications of parameters calculation of some typical simulation software, such as ATP-EMTP, EMTPE／EMTS, MATLAB／Simulink are introduced. An example of calculating the induction voltage and current of a 220 kV double-circuit lines on the same tower is provided, and the limits of previous mentioned simulation software are summarized.
