【摘要】：大规模电力电子装备接入使电力系统故障特征不仅受拓扑结构影响,而且受控制策略的影响,导致基于同步机故障特征的常规保护方法对含电力电子装备电力系统存在适应性问题。文中综述了国内外含新能源电源、高压直流、柔性直流的电力系统故障建模、故障特征分析及继电保护的研究进展,在此基础上对含大规模电力电子装备的电力系统故障特征分析方法提出思考,对保护原理的发展趋势进行分析总结。最后,提出考虑协调控制与保护的建议与设想,并探讨了进一步的研究方向。
[Abstract]:The fault features of the power system are not only influenced by the topology structure, but also influenced by the control strategy. The conventional protection method based on the fault characteristics of the synchronous machine has the adaptability problem to the electric power system with electric power equipment. The new energy source, high voltage DC and flexible DC are summarized in the paper. The research progress of power system fault modeling, fault feature analysis and relay protection is made. On this basis, the analysis method of power system fault features containing large scale power electronic equipment is put forward, and the development trend of protection principle is analyzed and summarized. Finally, the suggestions and ideas to consider the coordinated control and protection are put forward, and the discussion is made. Further research direction.
