针对巡检信息调取过程中无法兼顾巡检信息数据准确性和安全性的问题,设计了一种电力系统故障录波装置定值巡检信息主动调取方法。电力系统故障录波装置,根据GPS信号与接收机之间的时间差以及卫星星历,采集与计算定值巡检目标坐标信息,重新设计帧头数据格式以及代表意义,实现巡检GPS定位信息归一化;对调取传输过程中的加密算法进行优化,详细设计加解密过程,根据巡检信息记录模式确定多路径调取通信网络模型,保证调取过程中,电力系统故障录波装置能够无损呈现出真实的电力系统故障巡检信息数据。仿真实验结果表明,设计方法在信息调取过程中具有良好的传输安全性,且数据成功传输数量较多。

Aiming at the problem that the accuracy and security of patrol information are not considered in the process of retrieving patrol information,an active retrieval method of fixed value patrol information of power system fault recorder is designed.The power system fault wave-recording device collects and calculates the fixed value patrol target coordinate information according to the time difference between GPS signal and receiver and satellite ephemeris,redesigns the frame header data format and representative significance,and realizes the normalization of patrol GPS positioning information.It optimizes the encryption algorithm in the retrieval and transmission process,designs the encryption and decryption process in detail,and determines the multi-path retrieval communication network model according to the inspection information recording mode,so as to ensure that the power system fault wave-recording device can present the real power system fault inspection information data without damage in the retrieval process.The simulation results show that the design method has good transmission security in the process of information retrieval,and the number of successful data transmission is large.
