【摘要】：借鑒和應(yīng)涌流分析方法,分析特高壓一組換流變壓器空投時(shí)對(duì)稱性涌流的產(chǎn)生機(jī)理和變化特點(diǎn)�；诠こ虒�(shí)際參數(shù)建立詳盡的特高壓直流輸電的仿真模型,對(duì)特高壓換流站內(nèi)一組換流變壓器空投產(chǎn)生對(duì)稱性涌流現(xiàn)象進(jìn)行了仿真分析。闡明二次諧波制動(dòng)判據(jù)失去閉鎖能力造成特高壓換流變壓器大差保護(hù)誤動(dòng)的機(jī)理,為提升特高壓換流站大差保護(hù)的動(dòng)作可靠性提供分析手段。
[Abstract]:Using the method of inrush analysis for reference, this paper analyzes the generation mechanism and variation characteristics of symmetric inrush current during airdrop of UHV converter transformers. Based on the actual engineering parameters, a detailed simulation model of UHV HVDC transmission is established. The phenomenon of symmetrical inrush produced by air drop of a group of converter transformers in an UHV converter station is simulated and analyzed. The mechanism of the misoperation of large differential protection of UHV converter transformer caused by the loss of locking capacity of the second harmonic braking criterion is expounded. To improve the operation reliability of UHV converter station differential protection.
