有轨电车供电系统负荷等级与外电源方案

Discussion about Load Level of the Power Supply and Municipal Power Supply Scheme of Tram

从有轨电车供电系统外电源实施的角度出发,通过实际工程中有轨电车供电系统负荷等级的确定、外电源方案的要点以及报装过程中需要注意的问题,提出有轨电车的负荷等级可以为一级或二级负荷,应结合多方面的因素统一考虑。外电源方案应综合考虑城网电源形式、容量以及接线方式等,并在报装阶段注意表计、谐波等要点,从而使得有轨电车的供电网络能够良好地融入到城市电网中,提供可靠的电源。

The load level of the power supply could be classified into I or II by analyzing the application of the tram power supply system, the power supply load, power supply scheme and the focal points in the municipal power used in the actual project. The type capacity and the system line diagram of the municipal power should be paid attention to. In the installation phase of the municipal power, the meters and the harmonic wave should also be taken care of. Finally the power supply system can be integrated with the municipal power harmoniously, and supply reliable power to the tram.
