摘要:
      电力电子装备实现技术的快速发展使得其控制灵活、损耗低、结构简单、功率密度高等优势得以凸显,而对技术与经济指标的追求促进了电力电子装备在电力系统中的广泛应用,并在新能源并网、高压直流、柔性交、直流输电系统中发挥重要作用。大规模电力电子装备的应用使得系统故障特征不仅受拓扑结构影响,更受控制策略的影响,从而导致反应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。本文综述了国内外含新能源电源、高压直流、柔性直流、柔性交流、交直流混联电力系统的建模、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总结。最后,针对系统中换流器控制策略的重要性,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:
      With the innovation and improvement of power electronic equipments, the advantages of them are more and more prominent. Power electronic equipments play an important role in the new energy grid, HVDC transmission, flexible DC transmission, and has broad application prospects. The existence of large-scale power electronic equipments will lead that the fault characteristics of the system are not only affected by the topology, but also affected by the control strategy. This paper starts from the modeling method. Based on the fault characteristics and new protection principles of the classify study, the methods of analyzing the fault characteristic of power system with large power electronic equipments are put forward thinking, the development trend of new protection principles is summarized. Finally, in view of the importance of converter control strategy in the system, the ideas of coordinating control and protection are suggested.
