The mode of load shedding control has changed from the traditional mode of centralized load shedding to fast and precise control of interruptible branch load lines for users through the millisecond precision load control system.Firstly

the article focuses on the overall architecture of the precision load control system and the functions of the various levels of load shedding devices. Then

the control strategy of the precise load control system is analyzed.Finally

combined with the overall joint test

the engineering application of the system is described.Field debugging tests show that the system not only meets the requirements of speed and safety of traditional stability control system

but also achieves the accurate control of interruption load for enterprise users

and improves the fine level of emergency load shedding control.
