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 k V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。
Aiming at the problem of the influence of system harmonic, considers the influence of background high voltage direct current （HVDC） on AC harmonics caused by non-linear load, puts forward a practical test method for harmonic, and verify the validity of this method at 330 kV main transformer in Yinchuan East converter substation. The application result shows that the method can comprehensively analyze harmonic of AC system affected by HVDC in converter substation from the aspects of harmonic type and the operation and maintenance condition of HVDC, supplement the lack of theoretical analysis method, improve the practicability levels of the equipment condition analysis, power quality improvement and harmonic research.
