Research On Application Technology Of On-line Five-proof System In Substation

There are many electrical equipment in the substation.The current situation of substation accidents is frequent,and the security situation is facing severe challenges.In order to avoid many serious faults,at present,domestic power system substations have basically adopted microcomputer five-protection and other forms of protection systems.However,during the operation of the substation,there will still be certain problems,such as the monitoring system cannot effectively obtain the execution status of the operation ticket in real time and the relevant power equipment facilities and other location data cannot be monitored in real time during the operation.In order to avoid the occurrence of missing items during the execution of the switching action,the operating efficiency and stability reliability of the power system are greatly reduced,and the operator will also be subjected to greater operating pressure due to the complex power system.Therefore,it is necessary to research and design a high-performance five-proof system that monitors the power system in real time.With the rapid progress of society and the continuous development of science and technology,the power construction process has also been rapidly promoted.Substations with high intelligence are gradually put into practical applications,and the technology is continuously upgraded and optimized.This article analyzes and introduces the anti-misoperation blocking system of the power system substation at the current stage,and at the same time studies the operation mechanism and main features of the real-time five-proof system,and designs an online five-proof system for the power system substation.The designed system is based on wireless communication technology,which can: 1)Connect the temporary ground wire to the location information,dismantling action information,store information in the inventory,and leave the library information,accurately collect real-time,reliable supply and maintenance personnel and control personnel,Accurately grasp the use of the ground wire on the spot,and also can send the real-time status of the ground wire to the intelligent anti-error host,as the anti-misjudgment condition for the operation of the main equipment,to avoid the security caused by the error of the ground wire data and the loss ofdata Defects,which can effectively guarantee the stable,reliable and safe operation of the power system;2)The monitoring system can receive real-time information on whether the steps in the operation ticket are executed,avoiding the operator from frequently returning to the main control room during operation.The operation information of the computer key improves the operating efficiency of the operator’s trip.
