Automatic Implementation Method for Sequential Control Operation of Secondary Equipment in Substations Based on Improved HMM Model
In the process of sequential control operation,there is information exchange between multiple devices and systems,but there is a delay in information exchange,which can easily lead to misoperation.Therefore,a method for automatically implementing sequential control operations of secondary equipment in substations based on an improved HMM model is studied.Firstly,the improved HMM model is used to obtain the status information of secondary equipment in the substation,and the obtained equipment status information is managed accordingly.Secondly,based on the equipment status,divide the locking signal for sequential control rehearsal to determine which equipment can or cannot be operated.Finally,by setting the control sequence,the sequential control operation of the secondary equipment can be achieved.The results show that compared with the automatic sequence control methods based on monitoring systems and PLC,the error rate of the automatic implementation method for sequence control of secondary equipment in substations based on the improved HMM model is lower,ranging from 0.01%to 0.05%,and has a wide range of application prospects.
