摘要
鉴于传统的谐波测量方法已难以满足高压直流输电(HVDC)谐波测量的需要,介绍了一种基于Rogowski 线圈的HVDC谐波电流测量系统,整个系统的准确度优于3%,谐波检测部分的准确度优于1%,该系统完全不受 直流分量影响,高低压端完全光纤隔离,易于绝缘,适于HVDC谐波测量,也可用于一般直流谐波的测量。
Because conventional method of harmonic measurement hardly meet the need of harmonic measurement of HVDC, a new kind of harmonic measurement system based on Rogowski coil is introduced. The measurement accuracy of whole system can reach 3% or better, measurement accuracy of harmonics part reach 1% or better. The direct current component has no influence to the system at all because high and low voltage sides are totally separated by optical fiber. Therefore it is easy to arrange insulation and suitable for harmonics measurement in HVDC as well as for usual harmonics of direct current.
