摘要

为了掌握东莞电网运行的谐波状况及其危害

采用便携式电能质量分析仪FLUKE435对东莞电网电容器运行状况进行谐波普查

得到了大量典型负荷下的实测数据。根据相关文献和标准

对电容器谐波放大情况和谐波造成电网电容器过载、损耗增加、寿命减少等问题进行了定量的分析计算。计算结果表明

东莞部分变电站并联无功补偿电容器谐波危害严重

相关企业及部门应给予高度重视。

Abstract

To understand harmonics on Dongguan grid and their harm

the electric power quality analyzer FLUKE435 is adopted to carry out a survey of harmonics on capacitors in Dongguan grid.According to corresponding literatures and standards

quantitative analysis and calculation are performed for the harmonic amplification of capacitors

as well as the capacitors’ overload

incremental loss and shorter life caused by different harmonic pollution.The results show that the shunt reactive power compensation capacitors in some substations of Dongguan grid are seriously harmed by the harmonics

resulting in great waste of energy and equipment resources.
