摘要
针对电气化铁路运行情况复杂的问题,对其供电方式、负荷特点以及电能计量方式进行了介绍。指出影响电能计量的因素有:双向潮流切换、变压器空载运行、供电系统谐波等,并利用实验室相关设备模拟现场电能计量装置接线情况,分析各种错误接线情况下,对电能计量产生的影响。
Aiming at the complex operation of electrified railway,the power supply mode,load characteristics and energy metering mode are introduced.It is pointed out that the factors affecting energy metering include bidirectional power flow switching,no-load operation of transformers,harmonics of power supply system,etc.The wiring of field energy metering devices is simulated by laboratory equipment,and the influence of various wrong wiring conditions on energy metering is analyzed.
