Design of intelligent anti-overstep trip device based on optical fiber communication

针对当前防越级跳闸装置无法有效保证电力系统正常工作的问题,设计了基于光纤通信的智能防越级跳闸装置。首先对当前电力系统的防越级跳闸装置设计研究现状进行分析,找到引起防越级跳闸装置问题的因素,然后通过微控制芯片判断数模转换模块得到整定电流值,如果出现跳闸态势,就通过光纤通信智能启动防越级跳闸装置,对故障设备进行作断电处理,同时保证其他无故障供电设备的正常运行,最后模拟仿真实验结果表明,本文设计光纤通信的智能防越级跳闸装置能够在0.5s内将电力系统故障切除,完全满足实际应用的要求。

In view of the problem that the current anti-overstep trip device cannot effectively guarantee the normal work of the power system,an intelligent anti-overstep trip device based on optical fiber communication is designed.First,we analyze the current situation of the anti-overstep trip device of the current power system,find the factors causing the problem of the overstep trip device,and then judge the setting current value by the micro control chip. If tripping trend occurs,the anti-overstep trip device can be intelligently started by the optical fiber communication and the fault equipment is broken down,and the normal operation of other fault free power supply equipment is ensured at the same time. Finally,the simulation experiment results show that the intelligent anti-overstep trip device designed in this paper can remove the power system fault in 0.5 s and fully meet the actual requirements.
