| In recent years,with the continuous development of the national economy and the improvement of people's living standards,the power system has been rapid development,operation mode and system structure of power grid is becoming more and more complex,it has put forward higher requirements on the reliability of grid based data.The detection and identification of power system data is real-time network analysis of the important function of the electric power system,its purpose is through the detection and identification of grid based data flow testing,modern smart grid data remote transmission channel security,smart grid control technology required for basic data to support the system's real-time and accuracy.If sent to the smart grid based data grid control technology support system containing the error message,will not only affect the control system performance,more seriously,the normal operation of the control system will threaten personnel made decisions based on false information,and could threaten the security of the entire grid.Therefore,in order to ensure the safety of power grid operation,through data transmission to the remote channel abnormal data based data control technology support system for the detection and identification is of great significance to correction.In this paper,the development of intelligent power grid based data detection and identification system is based on the Quanzhou regional power grid control technology support system.Through the design of standardized data interface from the regulation of technical support system to obtain the grid based data,detection and identification system steady operation of basic data of balance node based on the outward diffusion of the island,for detecting and identifying and correcting on power system steady-state operation real-time data,and the identification results were analyzed using statistical analysis method,helps control personnel to troubleshoot the grid data transmission channel the problems of development;detection and identification of fault feature data and information theory based on the expert system,the use of protection configuration information in DTS can realize the automatic configuration of knowledge base of expert system,the expert system of forward and backward reasoning based on information theory for detection and identification of fault feature data in dealing with uncertain information advantages,the auxiliary monitoring personnel analysis on power grid fault,help site personnel identification of relay protection devices have no Abnormal,improve the efficiency of fault diagnosis and treatment,and ensure the safe and stable operation of power grid.In order to meet the practical requirements of intelligent detection and recognition system of intelligent data base developed rich function and convenient operation of the man-machine interface and provides a series of perfect system of auxiliary tool,the user can according to the actual demand of different modules achieve the desired function.The current system has been implemented and seamless access control technology support system in Quanzhou area,according to the real-time operation results,the system can carry out intelligent detection and identification of power system steady operation of basic data and fault data anomalies,solve the grid based data inspection methods are insufficient,maintenance workload,improve the efficiency and the level of intelligent control technology on the basis of the whole support system identification accuracy of the data and the control center of the massive data online control,auxiliary control personnel to improve the power grid construction,improve the safety and reliability of power grid operation. |
