对高速公路供配电系统电能质量的探析

Analysis on Power Quality of Expressway Power Supply and Distribution System

为契合高速公路、特别是智慧高速公路的快速发展,对高速公路供配电系统的电能质量进行探析是很有必要的。针对谐波、电压偏差、电压三相不平衡、频率偏差等高速公路的典型电能质量问题,从来源、影响及危害对谐波问题进行着重分析,并对其他电能质量问题也进行了阐述和分析,之后分析了电能质量问题的监测措施和方案,最后分析了高速公路电能质量问题的治理措施。分析结果对于保证高速公路供配电系统的安全稳定可靠运行具有一定的参考价值。

In order to meet the rapid development of highways,especially smart highways,it is necessary to analyze the power quality of highway power supply and distribution systems.This article focuses on the typical electrical energy quality problems of highways such as harmonic,voltage deviation,voltage three-phase imbalance,and frequency deviation.Based on the source,influence,and harm,the harmonic issues are analyzed,and other electrical energy quality issues are also expounded and explained.Next,the monitoring measures and schemes of the quality of electricity quality are analyzed,and finally analyzed the governance measures of highway electrical energy quality problems.The analysis results have a certain reference value for ensuring the safe,stable and reliable operation of the highway power supply and distribution system.
