高铁站房供配电系统三相不平衡与谐波分析

Analysis of Three Phase Unbalance and Harmonic of Power Supply and Distribution System of High-speed Railway Station Building

高铁客运站供配电系统是其整个电气系统的核心,而谐波问题一直是铁路与电力部门关注的焦点。本文针对某高铁站房出现的变压器零线电流相对较大的情况,对变电所供配电系统的电能质量进行测试分析,探讨谐波电流对电能质量的影响,为制定有效的治理方案提供参考。

The power supply and distribution system of high-speed railway passenger station is the core of the whole electrical system,and the harmonic problem has always been the focus of railway and power departments.With regard to the relatively large zero line current of transformer in a high-speed railway station,the paper analyzes the power quality test of the power supply and distribution system of the substation,and discusses the influence of harmonic current on power quality,so as to provide reference for establishing of the effective treatment schemes.
