摘要
文章针对上置变频器受保护单元设计容量限制,无法满足高电压穿越、次同步谐振震荡抑制等新的电网标准,因机舱空间限制,上置设计无法实现对硬件进行必要升级,以及变频器下置技改主要的技术难点及解决措施展开分析,并提出了一系列解决方案,进行了详细设计和实施与效果评估。通过文章研究,可以为变频器上下置技改提供一定的参考和借鉴,具有一定的研究意义和实际应用价值。
This paper analyzes the main technical difficulties and solutions for the technical transformation of the inverter,and proposes a series of solutions,aiming at the design capacity limitation of the protected unit of the upper inverter,which cannot meet the new power grid standards such as high voltage crossing and sub-synchronous resonance oscillation suppression,and the inability of the upper design to realize the necessary hardware upgrade due to the space limitation of the engine room.The detailed design,implementation and effect evaluation are carried out.Through the research of this paper,it can provide a certain reference and reference for the technical reform of up-down converter,which has certain research significance and practical application value.
