In order to solve the problems of one-key sequence control in substation,such as difficult acceptance and difficult transformation of power outage,a simulation verification method of one-key sequence control function based on digital twin technology is proposed,and a simulation verification platform for one-key sequence control function in substation is constructed in simulation environment.Based on the simulation verification platform,the state changes of primary and secondary equipment in substation are simulated,and the one-key sequence control function verification test is carried out without power outage of the equipment,and the configuration file of one-key sequence control system in substation is comprehensively verified.Through practical engineering applications,the proposed method is compared with the traditional manual acceptance method.Firstly,the verification logic is more detailed and comprehensive.Based on the simulation verification method,it can simulate various verification conditions of sequence control and improve the comprehensiveness of logic verification of sequence control configuration files.Secondly,the acceptance efficiency is higher.The verification testing work can be carried out before the start of new construction and renovation projects.Problems in the sequence control configuration files can be discovered in advance to ensure the smooth implementation of site work,thereby shortening the construction cycle of the project and improving the acceptance quality and efficiency of one-key sequence control in substation.
