摘要
电力系统中的谐波会造成电气环境的污染 ,必须进行有效的监测和抑制。本文提出一种电力系统最大谐波功率分量的快速估算方法 ,给出了估算公式 ,并对估算方法引起的误差进行了分析 ,仿真结果表明 ,该方法能够满足一般工程设计的要求 ,在各种电测仪表测量和治理谐波污染时 ,对于考察高次谐波功率分量的影响具有参考价值。
Harmonics in electric power system must be inspected and restrained efficaciously because it bring into being electric circumstance pollution.This paper gives a sort of speediness estimate method of higher harmonics power part in power system, and the method error is analysed, it suffice for common engineering, and have practicality reference value for seeing about influence of higher harmonics power part when a electron instrument is designed and harmonics pollution is treated.
