【摘要】:針對現(xiàn)階段低壓配電系統(tǒng)選擇性保護(hù)的局限性,概述了低壓多層級全范圍的新型選擇性保護(hù)的工作原理及關(guān)鍵技術(shù)。在此基礎(chǔ)上進(jìn)行了初步探索,設(shè)計(jì)了基于SPI通信技術(shù)的選擇性保護(hù)方案,并結(jié)合短路故障早期檢測技術(shù)對其進(jìn)行了選擇性保護(hù)的模擬試驗(yàn)測試。試驗(yàn)結(jié)果表明,所提出的方案能夠準(zhǔn)確、快速地判斷故障支路并發(fā)出分?jǐn)嘈盘?為實(shí)現(xiàn)低壓多層級、全范圍的新型選擇性保護(hù)技術(shù)奠定了基礎(chǔ)。
[Abstract]:In view of the limitation of selective protection in low voltage distribution system at present, the working principle and key technology of a new type of selective protection for low voltage multilevel and full range protection are summarized. On the basis of this, the selective protection scheme based on SPI communication technology is designed, and the simulation test of selective protection based on the early detection technology of short-circuit fault is carried out. The experimental results show that the proposed scheme can accurately and quickly judge the fault branch and send out the breaking signal, which lays a foundation for the realization of a new type of selective protection technology with low voltage, multi-level and full range.
