B dep - 535 backup protection for transformers 2dep 535变压器后备保护
Circuit local backup protection 自端入力后备保护
Dep - 535 is used as backup protection for transformers of 110kv or below voltage levels Dep 535微机主变后备保护装置适用于110kv及以下电压等级变压器的后备保护。
But the backup protection is still made up of simple protections based on the traditional principle 而对于后备保护,基本上仍然是由一些基于传统原理的较为简单的保护所构成。
Agent protection can prevent the maloperation and accelerate the backup protection . the maloperation of this protection is not a common phenomenon 大型电站agent保护对于保护整体性能的提高主要体现在防止保护的不正确动作和加快后备保护的动作速度。
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 后备保护装置后备保护装置是在其他保护装置动作失败或发生故障时动作的保护装置。
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 本文提出了对线路后备保护以及对主变差动保护的协调方案,该方案能够在特定情形下改善保护的性能。
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,对变压器保护装置的实时性、计算精度和大量数据运算速度的要求不断提高,单片机系统在很多场合下已经不能很好的满足用户要求。
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 文章在微机保护可靠性方面进行了较为深入的理论分析与计算,构造了状态空间模型,为带自检的变压器后备保护装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 通过对变压器后备保护装置进行较全面的动模实验,验证了保护装置的各项性能指标,同时实验结果表明该装置具有测量精度高、动作准确率高、可靠性高等特点。
