摘要

针对换流站高压直流(high voltage direct current

HVDC)对交流系统谐波的影响问题

考虑由非线性负荷造成的背景谐波的影响

提出一种谐波实测方法

并在银川东换流站330 kV主变压器进行了实测验证。应用结果表明:该方法可从谐波类型、运行及检修工况等方面分析受HVDC影响的交流系统谐波情况

弥补理论分析方法的不足

提高了设备工况分析、电能质量分析及谐波研究的实用化水平。

Abstract

Aiming at the problem of the influence of high voltage direct current (HVDC) on ACsystem harmonic

considers the influence of background harmonics caused by non-linear load

putsforward a practical test method for harmonic

and verify the validity of this method at 330 kV maintransformer in Yinchuan East converter substation. The application result shows that the method cancomprehensively analyze harmonic of AC system affected by HVDC in converter substation from theaspects of harmonic type and the operation and maintenance condition of HVDC

supplement the lackof theoretical analysis method

improve the practicability levels of the equipment condition analysis

power quality improvement and harmonic research.
