电力系统谐波检测与治理

随着国民经济和电力工业的飞速发展，用电负荷日趋复杂化和多样化。谐波污染已经成为危害电网、影响其他用电设备安全经济运行的重大问题。本文着重介绍了几种新兴的谐波测试方法，并对谐波的抑制措施进行了比较和分析，其中对无源滤波和有源滤波技术进行了进一步的阐述，为电力系统谐波的监测和抑制提供了参考依据，为实际工作的顺利开展奠定了基础。

Power system harmonic tests and harnesses

With rapid development of the national economy and power industry,the electricity loads are becoming complicated and diversified. The harmonic pollution has been become a great problem to endanger electric network and affect economical safety operation of other utilization equipments. This paper emphasized on some kinds of the latest detection methods for power systems harmonics. Hannonic restraint methods were compared and analyzed, and especially active power filtering and reactive power faltering were discussed. It is good reference to the detection and restraint of power systems harmonics, and helps in practical work.
