B dep - 535 backup protection for transformers 2dep 535變壓器后備保護(hù)
Circuit local backup protection 自端入力后備保護(hù)
Dep - 535 is used as backup protection for transformers of 110kv or below voltage levels Dep 535微機(jī)主變后備保護(hù)裝置適用于110kv及以下電壓等級變壓器的后備保護(hù)。
But the backup protection is still made up of simple protections based on the traditional principle 而對于后備保護(hù),基本上仍然是由一些基于傳統(tǒng)原理的較為簡單的保護(hù)所構(gòu)成。
Agent protection can prevent the maloperation and accelerate the backup protection . the maloperation of this protection is not a common phenomenon 大型電站agent保護(hù)對于保護(hù)整體性能的提高主要體現(xiàn)在防止保護(hù)的不正確動作和加快后備保護(hù)的動作速度。
Backup protection backup protection consists of protective devices , which are intended to operate only after other protective devices have failed to operate or detect a fault 后備保護(hù)裝置后備保護(hù)裝置是在其他保護(hù)裝置動作失敗或發(fā)生故障時動作的保護(hù)裝置。
This paper brings forward the cooperation scheme of the line backup protection and differential protection of main transformer ; this scheme can improve the performance of the protection 本文提出了對線路后備保護(hù)以及對主變差動保護(hù)的協(xié)調(diào)方案,該方案能夠在特定情形下改善保護(hù)的性能。
Now , the real time , precision of calculation and the velocity of runningdatum are required to improve on backup protection device for transformer . single - chip system can ’ t satisfy user ’ s requirements in many situations 目前,對變壓器保護(hù)裝置的實(shí)時性、計算精度和大量數(shù)據(jù)運(yùn)算速度的要求不斷提高,單片機(jī)系統(tǒng)在很多場合下已經(jīng)不能很好的滿足用戶要求。
Firstly , the reliability ofmicro computer protection is analyzed and calculated according to theory . at thesame time , the reliability of backup protection device for transformer with self - examis estimated by constructing state - module 文章在微機(jī)保護(hù)可靠性方面進(jìn)行了較為深入的理論分析與計算,構(gòu)造了狀態(tài)空間模型,為帶自檢的變壓器后備保護(hù)裝置的可靠性作出了估算。
Results testifiedthat the device has high measuring precision , high correct action , high reliability etc . now , the application of backup protection device for transformer based on dsp isvery wide from its researching 通過對變壓器后備保護(hù)裝置進(jìn)行較全面的動模實(shí)驗(yàn),驗(yàn)證了保護(hù)裝置的各項(xiàng)性能指標(biāo),同時實(shí)驗(yàn)結(jié)果表明該裝置具有測量精度高、動作準(zhǔn)確率高、可靠性高等特點(diǎn)。
