Application Of Sequential Control In Substation

Along with the vigorous development of China's power network,the domestic substation automation system has reached a high level of technology after many years of development.Full use of substation automation technology,the substation automation technology has achieved the monitoring,protection,control and production automation of the Intelligent substation.The substation operation ticket system are mainly based on the typical operation ticket and graphics verification.It does not have automatic reasoning drill coupon and intelligence.The extension of the sequential control mode makes it possible to implement the application in the substation.Combined with the actual work,the application of control in 220 kV substation in order Shunda road is analyzed in this paper.In this paper,the sequence control,substation automation technology,the operation rules and the expert system is analyzed first.Secondly,operation ticket system based on expert system and the application and implementation of the expert system in the order control of intelligent substation have been introduced.Then according to the sequential control design method,the realization of the application of sequence control operation ticket expert system in Shunda 220 k V substation is completed.Afte the application effect of the substation is analyzed,finally I put forward a blue print for the improvement of sequential control in the substation.
