基于无线通信的继电保护定值校核研究

摘要

In order to solve the problems of heavy relay protection setting value checking workload and missing and leaking currently data in transformer substation,this paper proposes a relay protection setting checking system based on wireless communication.The system collects the protection device setting and uploads to the host computer through the wireless transceiver module,and compares with the scheduling of the fixed value to verify the correctness of the real value.This system mainly holds the functions of getting device setting form,comparing setting value,modifying and rewriting,electronic signature,archiving and printing process,achieving check delivery paperless in substation.Hardware and software of the wireless checking design are discoursed mainly.Practical application in the system transformer substation shows that it meets the requirements of practical engineering and effectively improve the efficiency of the substation checking.%为了解决目前变电站继电保护定值校核工作量大、误核漏核等突出问题,提出一种基于无线通信的继电保护定值校核系统.系统通过无线收发模块将采集到的保护装置定值上传至上位机,并同调度下发的定值进行自动比对,验证定值的正确性.该系统主要包括定值单读取、定值单对比、定值单修改与写入、电子签名、报告存档与打印等流程,重点论述了定值无线校核的硬件构成和软件设计.变电站实际运用表明,该校核系统满足了实际工程的需要,切实有效地提高了变电站核验的效率.
