摘　　要：我国电气化铁路得到了大力发展。与此同时,电气化铁路牵引变电站负荷作为一种冲击性负荷,给电网电能的准确计量带来了重要影响。通过对电气化铁路牵引变电站现场电能参数的测量分析,分析了冲击性负荷电能表和普通三相电能表的计量结果差异产生原因,为推进非常规负荷电能准确计量技术的推广应用打下了基础。Electrified railway in China has been actively developed. Meanwhile, as a kind of impact load, the load of electrified railway traction substations has brought a significant impact to the accurate measurement on the electric power energy metrology. This paper measures and analyzes the field electric power parameters of several electrified railway traction substations, and analyzes the causes of the metrology result difference between the impact load electric energy meter and the ordinary electric energy meter. The research lays a foundation for the popularization and applica- tion of non-conventional energy load accurate metrology technology.
