电铁计量方式研究及运用
摘要
主要研究电能计量科学在电气化铁路上的应用。针对电铁牵引站谐波干扰大的问题
通过大量的试验和研究
提出应使用在牵引变压器高压侧安装三相四线制、基于“时分割乘法器”原理制成的全电子式电能表
才能减少谐波干扰
提高电能计量的正确性。对于其它非线性负荷的电能计量方式
也进行了研究和探讨。
Abstract
The application of electric energy metrology to electrified railways is mainly studied.Aiming at the problem of strong harmonic interference at traction substation of electrified railways
the full-electronic watt-hour meter of three-phase four-wire system based on the principle of "time division multiplier" is put forward to be installed in high-tension side of traction transformer by large numbers of tests and researches to reduce harmonic interference and to increase the correctness of electric energy measurement.The researches and discussions on the electric energy measurement methods of other nonlinear loads are carried out too.
