Development of Integrated Intelligent Unit with the Functions of Switch Control and State Monitoring
An integrated intelligent unit of high voltage switchgear was developed to adapt to the rapid development of equipment intelligentization for intelligent substation and meet the technical characteristics of the‘integrated intelligent equipment + integrated service system’ for future substation equipment. Switch controller IED
phase-selected closing IED and state monitoring IED were integrated into an integrated intelligent component with the functions of switch control and state monitoring according to the classification of function integration and fusion. The designs of device case
software and hardware
as well as the implementation of key technology
were analyzed considering the on-site operation of the integrated intelligent unit of high voltage switch
and the multiple CPU interaction technology was adopted to realize the functions of intelligent switch control
phase-selected closing and state monitoring. Test and measurement demonstrated that this integrated intelligent unit meets the expected requirements in terms of function
