Active Retrieval Method of Fixed Value Inspection Information of Power System Fault Wave-recording Device
Aiming at the problem that the accuracy and security of patrol information are not considered in the process of retrie-ving 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 accord-ing 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 al-gorithm 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 dam-age 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.
