Reasons and Countermeasures for Electrical Misoperation Accidents in Operating Substations
The current identification structure of anti-misoperation locking devices is generally set to independent mode,which leads to an increase in misidentification rate.According to the measurement requirements at present,this paper an-alyzes the causes of electrical misoperation accidents in operating substations,sets up operation monitoring nodes and con-trol mechanisms based on the analysis results of electrical misoperation accidents,and adopts a multi-level approach to im-prove the efficiency of preventing misoperation.On this basis,a multi-level anti-misoperation locking device identification structure is constructed,and a secondary verification method is adopted to complete the handling of misoperation acci-dents,thereby facilitate coping with electrical misoperation accidents.For the as experimental subjects,The proposed countermeasures achieves in test performed on randomly selected 6 auxiliary electrical equipment misoperation misidentifi-cation rates lower than 15%,indicating that the designed measures are more complete and effective,and can effectively reduce the probability of electrical misoperation accidents.
