| 摘 要： | 直流输电引起的谐波不稳定是指在换流站附近有扰动时谐波振荡不易衰减甚至放大的现象，主要表现为换流站交流母线电压严重畸变。为减小谐波不稳定发生的概率，保证直流系统运行的安全、稳定性，对谐波不稳定现象进行深入研究是十分必要的。文中分析了谐波不稳定现象产生的机理，在此基础上列举了该问题的几种主要研究方法，最后提出了谐波不稳定的抑制对策，对未来谐波不稳定的研究重点和抑制措施提出了一些建议。

| Abstract: | Harmonic instability caused by HVDC means that harmonic oscillation doesn't attenuate or even amplifies seriously when a disturbance happens in the converter station. For decreasing the probability of harmonic instability and guaranteeing the safety and stability of HVDC's operation, it is necessary to research the harmonic instability deeply. This paper investigates the mechanism of harmonic instability, and enumerates research methods basing on this mechanism. Finally it indicates the methods of trapping harmonic instability, and tables some proposals to the key of researching harmonic instability and control measures in the future. |
