| 摘 要： | 针对华东500kV电网电压谐波率较大的现状,分析了谐波源主要来自500kV变压器和高压电抗器。这些谐波源的谐波电流数值并不大,但由于500kV电网自身阻抗可能使谐波分量起了放大作用,本文对此作了分析探讨。本文还就谐波电压的测量方法、减小测量附加误差、谐波电压限值和控制对策作了叙述。

| Abstract: | Analysis of the high ratio of the harmonic voltage to that of the ECPN powernetwork showed that the sources of harmonics comes from the 500kV transformers and HVreactors. As the value of harmonic current is small, the impedance of 500kV network itselfmay lead an amplifying effect on the harmonic component. An investigation and analysis ofthe above phenominon is caaried out by the author. Also described are the measuringprocedure of harmonic voltage, how to minimize the measuring error and the limiting valueof harmonic voltage and its control. |
