【摘要】：正分析地铁配电系统中0.4 kV侧谐波电流的产生及危害,总结谐波治理的必要性并提出几种谐波治理方案,推荐采用有源滤波装置。地铁配电系统中大量使用非线性负载,如计算机、显示器、UPS、变频器和荧光灯等,它们在工作时会产生大量的谐波电流,谐波电流注入地铁配电系统后对系统造成的危害不容忽视。主要有以下几个方面:1)谐波使地铁电网中的设备产生附加谐波损耗,降低电网、输电及用电设备的使用效率,增加电网线损。
[Abstract]:This paper analyzes the generation and harm of the harmonic current of 0.4 kV side in the subway distribution system, summarizes the necessity of harmonic treatment and puts forward several harmonic treatment schemes. The active filter device is recommended. A large number of nonlinear loads are used in subway distribution systems, such as computers, displays, UPSs, frequency converters and fluorescent lamps, which produce a large amount of harmonic currents when working. The harm caused by harmonic current injected into subway distribution system can not be ignored. There are several aspects as follows: 1) Harmonic causes additional harmonic loss of the equipment in the subway network, reduces the use efficiency of the power network, transmission and power equipment, and increases the line loss of the power network.
