| 摘 要： | 随着高压直流输电的发展及多馈入直流输电系统的逐步形成,多馈入直流系统的谐波不稳定问题日显突出。从谐波不稳定产生的机理出发,分析了导致谐波不稳定的交/直流系统频率互补谐振条件,以国际大电网会议(CIGRE)提出的高压直流输电标准测试系统为原型,在Matlab/Simulink仿真平台建立了多馈入直流系统的模型,并基于该模型对多馈入直流系统中各交直流网络间的谐波相互影响进行了仿真与分析。结果表明,该模型能对多馈入直流系统的谐波特性进行准确、有效的分析。

Simulation Study on Harmonic Instability of Multi-feed DC System |
| |
| Abstract: | With the development of HVDC and the formation of multi-feed DC transmission systems, the harmonic instability of multi-feed DC system becomes more obvious. Based on introducing the generation mechanism of harmonic instability, this paper analyzes the complementary frequency resonance conditions for causing the harmonic instability of AC / DC systems. A model of multi-feed DC system is given in Matlab/Simulink by taking the HVDC standard test system proposed by CIGRE as a prototype. Based on the model, the impact of the mutual harmonic HVDC system in each of AC and DC networks is simulated and analyzed. The simulation results shows that the model is capable to analyze the multi-feed HVDC system harmonic characteristics accurately and effectively. |
