摘要
本文从谐波对电能计量准确性影响、谐波对电能计量合理性影响两方面出发,采用理论分析、实验室测试和电气化铁路牵引变电所电能表现场测试相验证的方法,研究了电铁供电谐波对计量的影响。对不同谐波功率方向、不同谐波含量情况对计量的影响分别进行了理论分析,并进行了试验验证。依据电铁供电谐波统计资料,在实验室模拟电铁实际负荷情况,研究电铁供电谐波对多种电子式电能表和机电式电能表计量的影响。在电气化铁路牵引变电所现场安装基波电能表,通过一段时间的电量累计,研究了电铁供电谐波对计量影响的实际情况。
This essay discusses both the electric metering accuracy and the electric metering rationality of harmonics. By theory analyzing, testing and verifying in lab and electrified railway station, this essay gave gives the research results for the harmonics influence on electric energy measurement. By the harmonics statistic data of the electrified railway, in the lab, we simulated the supply of the electrified railway, and researched the harmonics to the energy meters. We fixed fundamental wave energy meter in electrified rail way station, by accumulative total energy of a period time and researched the fact influence of the harmonics on the energy meters.
